Yūki Terumi

Yūki Terumi (ユウキ＝テルミ), whose real name is Susanoo (スサノオ), was one of the Six Heroes, as well as the creator of the Blue Grimoire, one of the founders of both the World Void Information Control Organization and the 7th Agency. He is a playable character since BlazBlue: Chronophantasma (indirectly playable initially in Hazama's Unlimited Form). He was the main antagonist of the C-series of BlazBlue.

Appearance
Terumi wears a hooded yellow cape with black markings and large rolled-up cuffs along with long black ribbons and bandages across his arms. He also retains a few articles of clothing from Hazama’s form, including an open shirt beneath his vest that shows his chest, a loose black tie, two belts, black pants and the same steel-toed-shoes with knives hidden inside their heels. When he activates Overdrive mode, his hood comes off for a brief moment, revealing his green upwards-spiking hair that both Hazama and Kazuma have involved whenever Terumi fully took over their bodies. And like his two vessels, Terumi has the same golden snake-slit-styled eyes.

In his ghost form Terumi is a black mass with green energy on him with his face having a wide red smile and only one glowing green eye. During the Great Dark War, before fusing with Kazuma, Terumi wore a Magick Association uniform shirt, a tattered orange cape with a hood, and long black ribbons across his arms.

During Phase Shift 1, his hair is not shown, as he is always cloaked. However, concept art in later art-books has revealed that Terumi’s hair remains the same as it is today: spiked-up and green-colored. Whilst as the Black Susanoo he resembles a shadow version of Hakumen with green lines all over him with his mask having a glowing smile and evil, glowing eyes.

Personality
Cruel, insane, sadistic, selfish, yet sharp-witted and cunning, Terumi delights in the suffering of others, both physically and mentally, and relishes pure chaos. He happily provokes and manipulates others for his own amusement, and ruthlessly tortures anyone who irritates him or gets in his way. Unsurprisingly, this has earned him the contempt of almost every character in the BlazBlue universe, most notably Ragna, Kokonoe, and Nine. However, he is prone to enraged tantrums and sometimes panics when things don’t go his way, and absolutely hates being touched by other people. In the English scripts, his common way of swearing involves religious and excretory curses, while he resorts to sexual lingo whenever he is personally angered or disgusted.

At first when he was possessing both Kazuma and Hazama, Terumi's personality influenced their independent traits to merge with his own, which made the two of them rather affable at best alongside Terumi's blatant cruelty. However, as time goes on due to the fact that the Mind Eater curse inflicted upon Terumi caused his fusion with both vessels to be incomplete, Terumi’s personality was instead replicated by Hazama himself mixed in with his affable traits; Terumi's own consciousness slept deep within Hazama for some time to make up for this before being forcibly materialized/split apart from both of his vessels, with Terumi's own will regardless being the stronger one that influenced both vessels to follow his way of life.

Furthermore when the two end up separated as of Centralfiction, Terumi served as a more clear foil to both Hazama and his original self, Susanoo; Hazama as a result of gaining his true own will became less outwardly-barbaric, spoke formally more often and was less willing to interfere with other people's businesses most of the time, while Terumi was shown to be more blunt and prone to inflicting violence compared to Hazama's more passively-manipulative side which earned him the status as a wild card of sorts due to manifesting his own will apart from Terumi's. It is to the point where even Terumi himself cannot fully trust Hazama's ambiguity in regards to specific duties, and when Terumi was greatly weakened at one point, Hazama was able to house him in his own body as usual but without any of Terumi's influence interfering with Hazama's newfound will.

Meanwhile, his personality as Susanoo is more composed and focused on rage and hatred rather than the sadistic tendencies displayed as Terumi. As Susanoo, "Terumi" is more collected, but beneath the seemingly stoic demeanor is a boiling and explosive rage which he uses to fuel his destructive tendencies. He views all others as beneath him and treats them with utter disgust, referring to them as either trash or waste (his primary Japanese pronoun for everyone is "temē"). He constantly reminds those who dare to defy him the fact that he is a true god.

Although overconfident and prideful, Susanoo ever since he gained his own will, despises his meaning of existence as the brother of Amaterasu and they are essentially linked to one another, with his actions ultimately adhere to what she desires from him, and he hates her for that. Thus, Susanoo seeks to destroy all of her creations out of spite for this fact and expresses that her suffering is his salvation while seeking true freedom. Also as Terumi, he states another reason for his desire for freedom is to punish the humans who have tried to abuse god's power by causing many catastrophic events throughout many timelines/possibilities, including those who have abused the emptied Susanoo Unit for their own desires.

History
In the beginning, Susanoo was one of the original Sankishin units and was a guardian of the Master Unit Amateratsu alongside Tsukuyomi, being nothing more than a mindless robot as an extension of her will. However, Susanoo gained a will of its own and grew to hate Amateratsu. He then rebelled and separates from his body, becoming Yūki Terumi and goes on to spite Amateratsu in various ways while also plotting to kill it. Meanwhile, the emptied Susanoo Unit's power went on to be used for mankind's own desires until Terumi reclaimed it for himself at some point in time.

BlazBlue: Phase 0
When Relius Clover and Shūichirō Ayatsuki worked on an experiment to examine the Gate, Terumi offered his knowledge, as well as the Susanoo Unit (his original body), for their studies. During Relius’ trial experiment, the Black Beast emerged from the Kiln. Relius was swallowed by the Kiln, Terumi’s physical form was destroyed, and his spirit form took heavy damage. It took five years for his spirit body to heal, after which Terumi contacted Relius in order to ask the whereabouts of his next body that Clover promised to prepare. The body, Kazuma Kval, was placed in Magic City of Ishana, which was protected by a ridiculous barrier that Terumi couldn’t overcome in his current state. Instead, he opted to calling directly into Kazuma’s mind from the Boundary.

BlazBlue: Phase Shift 1
Six years after the first arrival of the Black Beast, Terumi’s calls are continuously ignored by Kazuma. That changes, when Kval’s life is threatened for the first time in his life, by the assault of Tomonori. This allows Yūki to finally reach Kazuma, who in such a situation was ready to grab any chance of survival. The next day, after Kval woke from his dream, Terumi, as a delusion, appeared clearly for the first time before him. As Kazuma didn’t recognize him, Terumi introduced himself and began tempting him with the Blue.

The Blue was a tempting proposition, as it not only gave Kval a purpose, but also offered him a chance to reclaim what he lost, including his memories. Thus, Kazuma begins his search for the Blue. After Kval fails to find anything about the Blue at the library, Terumi again appears in order to aid him in his quest. He surprises Kazuma with not only vast knowledge about the Magic Association, but also about Kval’s own thoughts. That is because the only place that Terumi existed in Ishana, was in Kazuma’s own mind. After Yūki’s reveal that the Association’s secret information, hidden in the Sanctuary, is a way to reach the Blue, they are again imprisoned in a barrier ars, this time performed by 3 half-beastman assassins. In exchange for Kazuma’s promise to obtain the Blue no matter what, Terumi takes care of the 3 assailants. Later that night, a worried Trinity comes to Kval’s room, asking if something happened as Nine again had felt a strange power (ars), like the last time that Kazuma was attacked. After she leaves the room, Terumi manipulates Kazuma into believing that Trinity’s real purpose was to monitor him all along.

After Kazuma doubts are confirmed during the meeting at the café with Trinity, Celica and Nine, Terumi appears again, leading Kval to a part of Ishana’s Barrier that had a hole created in it by the beastman. There, he forces Kazuma to realize that he can use this to his advantage in obtaining the Association’s secret information.

Finally, Kazuma manages to reach to the bottom of the Sanctuary, where the man-made Kiln is hidden. Kval calls out to Terumi, who appears to congratulate him for reaching this far. Afterwards Kazuma gains information regarding himself and Terumi from the Boundary, by touching the Kiln. After realizing what he is and noting that he has indeed regained what he has lost, as Yūki promised, they perform the ceremony in preparation for the complete fusion. Right after that, Tomonori appears again, this time wielding the Hihiirokane and battles against Kazuma. With the released Hihiirokane, Tomonori gains advantage over Kazuma. Kval, wounded, while standing at the top of the central part of the Kiln, feels like the power of the Boundary is entering him, as if madness is starting to engulf and possess him, it is Terumi entering Kazuma’s body through the Kiln. The fusion instantly takes place, the rightful soul enters the rightful body, fitting each other perfectly. It is no longer Kazuma or Terumi, it is Kazuma-Terumi as one, the fusion is complete, Kval’s hair spikes up, eyes open wide and he gains the ability to wield the Ouroboros, as well as the snake manifestations. With those now in his arsenal, Kazuma manages to defeat Tomonori. Still wounded from the fight, Terumi tries to leave the Sanctuary, but instead encounters Valkenhayn R. Hellsing and is easily defeated by him. He is then taken to the Alucard castle, where he is sealed by Clavis.

Soon after, Konoe Ayatsuki Mercury, who realized that Terumi’s power was needed to defeat the Black Beast, releases him from his prison and casts Mind Eater on him to use him as a puppet during the Great Dark War. Before the spell hit, he split his and Kazuma’s mind from each other so that his controlled mind was trapped inside his body while Kazuma took over.

BlazBlue: Phase Shift 2
During the action of the novel, he is forced to follow Nine’s order, but when no one is watching him, Kazuma takes over to act behind her back.

As Seven and Eight plan to go against Nine’s order to dispose of the first Arch-Enemy Event Weapon before it’s complete, Kazuma appears to aid them in their schemes. He personally introduces them to the Void Information Management Agency and their collaboration with the organization begins. He is also shown seeping poisonous words into Trinity’s ears.

During the Black Beast’s reappearance, he was part of Ishana’s mage unit.

BlazBlue: Phase Shift 4
After the war, Kazuma eventually manipulated Trinity Glassfille, who had feelings for him, into releasing Terumi from the spell. After his release, he quickly killed Konoe and Trinity, threw their bodies into the Boundary, and proceeded to find Hakumen and Jūbei so he could kill them. Terumi had the upper hand, but Jūbei used Tomonori’s Sekigan to force him to materialize. As he was taken by surprise, Hakumen grabbed him and jumped into the Kiln while Jūbei closed the gate.

Terumi was sealed inside the Boundary for some time before being finally released by Takamagahara. He met Relius, who had just finished his time leap after being swallowed by the Kiln, again and the two resumed their partnership. Relius apparently made Terumi a new body called Hazama afterwards. However, because of the after effects of the Mind Eater curse, Terumi and Hazama are forced to remain separate entities sharing the same body.

At some point, Terumi in his new body went to burn down and attack the church housing Celica, Ragna, Jin and Saya upon the barrier being released around the locale; this resulted in Celica being killed by Terumi's own hands, severing Ragna's arm (both with Jin's assistance), and the kidnapping of Saya to create clones of her. Terumi would then earn Ragna's eternal contempt from this point onward, and Jin's memories would be subsequently muddied/erased by the powers of the very former.

During the creation of Mu-12 (who was one of the aforementioned Saya's clones), the 7th Agency desired to merge both Hazama and Noel to make a Black Beast, but Takamagahara stoped their plans by using Takemikazuchi, destroying the facility, leaving Mu incomplete, and adopting the new identity, Noel Vermillion.

At some point in time, TR-0009 Tager had encountered Terumi in his ghost form, as he recalled seeing a “green shadow” in Ikaruga. Yūki was also present at the time that Jin had slain Tenjō Amanohokosaka, in order to erase Jin’s memories of what he had seen and concluded afterwards for the second time in Jin's life.

BlazBlue: The Wheel of Fortune
Terumi briefly appears in the original timeline when he switched faces with Hazama in order to fight Hakumen. After fighting for a brief while, he shouted out for Relius to help him and, after Hakumen attacked the Puppeteer, the two engaged the leader of the Six Heroes. After the Event Interference occurred, Terumi began to throw up as he had reached the limit of his self-observation. He cockily told Relius to shut up and that he would handle the rest.

BlazBlue: Calamity Trigger
During the events of Calamity Trigger Terumi appeared as a NPC both in his ghost form and taking over Hazama’s body a couple times. During Rachel Alucard’s story mode, Terumi appeared twice, the first time mocking Valkenhayn R. Hellsing, and the second time mocking Rachel herself.

After the final fight of the True Ending in Calamity Trigger, he appears before Noel and Ragna, and after Rachel arrives, he loses his calm demeanor. His hair spikes up and his voice becomes much louder. Rachel and Ragna, having recognized Terumi from the attack on the church years before, attack him immediately, but he simply shrugs it off, and begins to taunt Ragna over the church attack before departing.

BlazBlue: Continuum Shift
Terumi appears as the main antagonist of Continuum Shift where he appears only in Hazama’s astral or when he takes over in story mode.

It is revealed that Terumi, like Hakumen and Rachel, will fade away without an Observer. Takamagahara, and later Mu (with the power of the Eye), with whom he shared a Life Link, observed him in BlazBlue. However, Mu lost her power after she turned back to Noel and Takamagahara was attacked by a magical virus from Phantom, losing its power. Terumi did not fade away, however, because he had awakened Hades: Izanami, her vessel Saya is observing Terumi. As an added measure, he is using Ragna’s hatred as a force to bind him to this world, as well and the reason he was able to destroy Takamagahara.

BlazBlue: Chronophantasma
He was tasked with erecting a barrier over the Ikaruga region, preparing the 13th Prime Field and managing Tsubaki Yayoi. Among his other goals was taking care of Ragna the Bloodedge and the remaining Six Heroes.

As part of their plan, Trinity and Rachel utilize Thundering Roar: Muchōrin on a more powerful level to materialize Terumi in the real world. To do so, they assault Terumi’s mind and agitate him by having various illusions of characters he finds particularly annoying to taunt him, such as Bang, Ragna, and his fellow Heroes. Prior to Amaterasu’s forced intervention, he even has to fight himself, who claims that even Trinity might have not predicted this far. Eventually, Terumi’s consciousness is forced to become the front side while Hazama’s becomes the backside. The Heroes catch him downtown Yabiko, and almost kill him if not for Phantom’s intervention. Terumi somehow manages to become the backside later, and meets Trinity again as the Heroes split up to look for him. He easily defeats Trinity, but Hakumen appears to save her. Terumi traps both of them in Phantom’s Infinite Corridor to lock them away forever, but Trinity and Hakumen use the power of Muchōrin to confront the source of the barrier.

In the finale, he goes to the monolith as told by Hazama and meets Hakumen. As Hakumen tries to ascertain his existence, Terumi blames what happened on Trinity and Rachel, saying his recognition is all over the place despite being finally set free. He then encounters Hakumen in battle. Terumi gains the upper hand by not allowing Hakumen any opening to charge his technique. However, as Trinity ambushes Hazama, the connection between him and Terumi puts the latter into a temporary halt. Using the chance, Hakumen uses Time Killer on Terumi and kills all of his “time”, effectively destroying him.

BlazBlue: Centralfiction
“Phantom of Labyrinth”=

Despite Hakumen’s death blow, Terumi manages to survive by self-Observation, leaving himself in the same state he was in during the attack on Celica’s church years before and prior to Noel observing him while also leaving him immune to most direct forms of death. Living on what little time it gives him, Terumi finds himself needing to merge again with Hazama within the week, or his self-observation will give out and he will perish. Despite locating Hazama, Terumi finds that not only has Hazama gained free will and his own desires, but he no longer wishes to be Terumi’s vessel. Even if he did, Terumi is unable to merge with Hazama again due to an unexplained side-effect of what Trinity did to them at the monolith during the events prior. “Nightmare Memory”=

With Hazama no longer a viable option as a vessel and his time rapidly running out, Terumi is forced to change tactics and find himself a new vessel entirely. “The Replacement Blue”=

To this end he discards his fragment of Blue, and breaks into Alucard castle. There, he makes his way to an unobserved place within and finds his first target, the coffin of Clavis Alucard. After fighting a duplicate of himself created from the security surrounding the coffin, Terumi then steals a cube, from the coffin, which is actually the sealed form of Hihiirokane, and states that with it he would obtain an unrivaled vessel and destroy everything. "Centralfiction"=

Terumi’s plan comes to fruition when he ambushes Hakumen with Hihiirokane in its chain form, destroying his soul. With the Susanoo Unit empty it is revealed that it is in fact Terumi’s original body. Ragna, Jin, Noel, Tsubaki, and Trinity can only look on in horror as Terumi merges with the Susanoo Unit once more. Body and will reunite and Takehaya Susanoo, brother of Amaterasu, is reborn. In his original form once more, Terumi kidnaps and assimilates Noel into himself and in doing so renders himself completely immune to Event Interference, rendering him almost completely invincible.

He goes on to defeat Es at the gate, telling her the reason she lost is that Ragna is the true Guardian of the Blue, not her. With Es defeated Jin attacks Susanoo only to be easily defeated. The last man standing, Ragna activates the Blue Grimoire as the only one who can stop Susanoo. After a vicious battle, Ragna attacks Susanoo head on and once in reach of him utilizes Soul Eater and rips an enraged Terumi out of the Susanoo Unit once more, allowing Jin to take control of it before sending them inside the gate into the Blue Horizon, which resides in the Boundary. In the Boundary after Terumi’s speech about the true nature of the Blue, Ragna then reveals his trap to Terumi: as the Susanoo Unit is Terumi’s true form, by having Trinity place Jin within it the world perceives Susanoo as a mighty hero and Terumi as one of the legendary Six Heroes that defeated the Black Beast. As a result, no one is afraid of him and Terumi is unable to use that fear and hatred towards him to anchor himself to the world any longer.

Now truly vulnerable and out of options, Terumi engages Ragna in one final battle to the death, attempting to take the True Blue for himself to finish what he started. The battle reaches its climax as Ragna successfully defends himself from Terumi’s Unholy Wrath of the Basilisk with Black Onslaught. With Terumi left wide open, Black Onslaught’s final strike impales him upon Ragna’s sword. Fatally wounded, he wishes eternal suffering upon Ragna. With one final thrust from Ragna, Yūki Terumi finally dies, his passing punctuated by his maniacal laughter.

Powers and abilities
Stated by Jūbei to be a powerful magic-user, Terumi has proven to be one of the most powerful characters in the BlazBlue series. Terumi’s primary ability is to feed on the hatred of others to make himself stronger, and it also allows him to anchor himself into the physical world. In ghost form, Terumi is intangible and immune to most attacks save those that are specially designed to harm ghosts, such as Tomonori’s Hihiirokane. Despite his incorporeal state, Terumi is still able to physically interact with the world. Terumi was shown to be able to erase memories by “eating” them, commenting that they are delicious. He used this ability twice, both of which were on Jin Kisaragi.

His magic is even strong enough to be used on the level of observation, where as of his demise in Chronophantasma, Terumi was able to observe himself in order to stay alive from Hakumen’s technique and seemingly immune to death as a ghost in Centralfiction; however, such levels of self-observation put much strain on his power to only being able to maintain his existence to merely a week before he perished for good.

In battle, Terumi is a powerful, vicious, and savage opponent, able to fight on par with both Hakumen and Jūbei. In line with his sadism, Terumi’s fighting style revolves around inflicting as much pain on his enemy as possible before finally killing them. In contrast to Hazama, who relies on his Ouroboros chains and whose fighting style was graceful and dance-like, Terumi’s style is far more barbaric and cruel, relying more on his serpentine spirits, butterfly knives, and knives within the heels of his shoes. He is also adept in the use of his Ouroboros for direct attacks, using it for his Snake Bite, Retaliating Fang, Venomous Bite, and Screeches of the Condemned attacks, being these the only times he uses it as such. Terumi is also able to access the power of the Susanoo Unit despite no longer owning it, using it to transform into the Dark Susanoo, a black and green shadow version of Hakumen, and deal the final blow in his Astral Heat, Unholy Wrath of the Basilisk. However, he often lacks high one-shot damage, which ties into his preference of inflicting gradual damage in order to make his opponent(s) suffer.

Gameplay-wise, Terumi is a character with more Distortion Drives than special moves. His Drive, Force Eater (フォースイーター), is a foil to Ragna the Bloodedge’s Soul Eater Drive. Instead of absorbing life force, it instead allows Terumi to absorb extra magic element, reflected in gameplay to have his Heat Gauge gain become increased while negating the damage-based-gain for his victims, allowing him to utilize his Heat-related abilities far more than any other character and having several combo opportunities to use them, making his potential damage output outright devastating; the power of Force Eater is also likely explains his ability to consume memories.

His Overdrive is Nightmare Reaper (ナイトメアリーパー), which strengthens Terumi’s Drive attacks and allows him to absorb the opponent’s Heat Gauge, and making it work more similar to the aforementioned Soul Eater in the said state.

Tying into his high level of magic prowess, his will alone was enough to make it so that Hazama, a later vessel of his after Kazuma Kval, followed Terumi's own goals and way of life as though they were fully his own despite the Mind Eater curse forcing them to be separate entities for quite some time. It was only when Terumi was severely weakened at some point during the events of Centralfiction that Hazama with his own will was able to house the former ghost inside of his body once more without Terumi's influence fully coming over him, with Hazama adding to the fact that Terumi's level of powers were too high of a level for him to match up to. The two unlike before, often communicated with each other separately during such events.

Trivia

 * Naming
 * “Yūki” (幽鬼) in Japanese means “ghost” or “revenant”. His last name translates from Japanese as “beautiful shrine” and is a feminine name, although admittedly rare.
 * His technique naming-motif is snakes, which also parallels his nature that nods to how snakes are negatively portrayed in most forms of mythology and media. Hazama follows this motif as well.
 * In nod to this as a contrast Hazama’s crest being akin to the Ouroboros, Terumi’s crest instead resembles a caduceus, or “herald’s staff”, which consists of two snakes coiling around a winged staff. In Greek mythology, it was carried by Hermes, a cunning trickster god who could freely move between the boundaries of worlds as an emissary of the gods and conductor of souls into the afterlife, which overall nods to Terumi’s nature in both his personality and the fact that he was originally a god-like being.
 * Oddly enough however, the image of the caduceus in the form of dual-coiling-green-energy-snakes appears only around the darkness pillars emitted from Hazama's Overdrive-enhanced Jayoku Hōtenjin and his Active Flow-version Exceed Accel (Meija Gekkōga).
 * Terumi also has his Distortion Drive Orochi Burensen (including his Astral Heat, Orochi Zantō Reppūga), which like Hazama’s Orochi Burensō, is a nod to the Shintō mythology beast, the Yamata-no-Orochi.
 * Other
 * Terumi is the first character to physically interact with the losing character after a match, stomping on them and occasionally kicking them off the screen.
 * Due to a glitch, Terumi’s actions mentioned above count as a combo in Score Attack, with his repeated stomping on Ragna giving him the most points.
 * Just like Hazama, when Terumi is electrocuted, an imprint of his ghost form is revealed instead of a skeleton.
 * It is implied that Terumi’s ghost form can materialize at will, but still needs a vessel to anchor his existence in the living world.
 * Terumi has more Distortion Drives than any other character, with a total of 6.
 * Along with Jin, Noel, and Tsubaki, Terumi also has a playable alternate form, Hazama, his former vessel. He also has another playable alternate form, which is Susanoo, his original body.
 * Also, Terumi has the most playable forms of any character in-game, with a total of 3 (Hazama, Terumi, and Susanoo).
 * When he was the user of the Susanoo Unit, he was acting upon the name of Takehaya Susanoo no Mikoto, as by recognizing himself as such in his Astral Heat, he gains the form of the Black Susanoo, which would be the most accurate description of Yūki Terumi, as he is recognized as such by the Eye of the Blue. It is also under the name of Susanoo that he opposes Amaterasu.  In Centralfiction, it is then revealed that Terumi's true name is Susanoo as he was the original will of the Susanoo unit and that his original body was always the Susanoo unit.
 * In his BlazBlue: Chronophantasma Arcade Mode, Terumi is the only character who has a Mirror Match as a mid-boss; this also repeats in Act 3 of BlazBlue: Centralfiction’s arcade mode where his Mirror Match is a final boss instead.
 * Among Terumi’s battle clips, there are some that directly refer to Kazuma, such as:
 * “Kazuma Kval”.
 * “It’s been a while, Kazu”.
 * Terumi’s backwards throw animation changes when used on Litchi. Instead of throwing her with his flip kick, he has an added animation: he feints his initial kick and finishes with his other leg, which is a completely unique animation taking a few more frames than normal.
 * Terumi’s gag scenario in Chronophantasma: Extend, akin to Hazama’s in the original Continuum Shift, directly references and expands on a trait of his from his profile, which is his passion for live musical performances.
