Jin Kisaragi

Jin Kisaragi was a Major and 4th Thaumaturgist Squadron Commander of the Novus Orbis Librarium, and Ragna and Saya's brother. He is a playable character in the BlazBlue series.

Information
When Jin was a little boy, he was very dependent on his older brother, Ragna, for affection and constantly pestered him to play with him. He saw his sister Saya as an obstacle of getting his brother's attention and constantly bullied her in retaliation. Eventually, Ragna decided to look after the sickly Saya and distanced himself from Jin, thus increasing his jealousy.

It was then Yūki Terumi entered Jin's life and told him about the Black Beast, that it would be born from Ragna, and that he is destined to destroy it. Deciding that his brother must pay for his ignorance, and to get rid of the obstacle between them, Saya, Jin left Terumi to do as he pleased, including burning the church where they stayed and murdering their caretaker. When Ragna arrived, he only watched in shock as Terumi cut off his arm, and kidnapped Saya. Jin later vanished from Ragna's life, and apparently his memory of that incident was blocked off.

Jin was later adopted to the high-esteemed Kisaragi family. With his talents, he rose up in the ranks of the Novus Orbis Librarium and was given by Imperator Librarius the Nox Nyctores named Mucro Algesco: Yukianesa, but his other siblings never trusted him, thinking that he only got his ranks due to his adoption. Indeed, Jin himself felt completely empty even after being showered with awards and ranks (which included the stopping of the Ikaruga Civil War).

Calamity Trigger
When the rumors of the "Grim Reaper" arose, Jin felt a sudden urge to meet him, which caused him to abandon his post and head to Kagutsuchi to find out more about the Reaper. When it turns out to be Ragna, Jin became ecstatic to meet his beloved brother and his psychosis caused him to be eager to kill him and fulfill his destiny.

During one of the time-loops, Ragna and Jin's battle is interrupted by Nu's appearance and she ends up throwing herself along with Ragna into the Cauldron. Never wanting to lose his brother again, Jin jumps into the Cauldron despite his wounds and is sent back in time to the year AD 2099/12/31, where he meets Rachel Alucard and is offered a chance to be a true hero. From this point on, Jin becomes one of the Six Heroes, Hakumen.

Continuum Shift
During the True Ending of Calamity Trigger, Jin is incapacitated badly by Ragna and is sent to the hospital. When he awakes, he finds that he is being targeted by NOL for assassination, thus runs away from the hospital and goes into hiding while cutting off all ties with the Kisaragi family. However, he also hears about Ragna and his subordinate Noel Vermillion staying together, and as Noel reminds him very much of Saya, Jin decides to attempt to kill them out of jealousy. Over time, his willpower becomes strong enough to resist Yukianesa's influence, thanks to the help of Jubei. Jin assisted Hakumen in attempting to defeat Mu, but neither had any success. He, Ragna and Noel found that Hazama is working for their sister Saya and Tsubaki sided with them, which is a shock to him. After they left, he, Ragna and Noel decide to become stronger and finding what the true motive is. Jin is currently training under Jubei, possibly to better control Yukianesa.

In the Wheel of Fortune Drama CD, which shows the timeline where Noel did not exist, it is revealed that when they were young, Jin and Saya were very affectionate towards each other. They were happily playing together, and Jin's attitude towards Saya is completely different from the current timeline, with Saya giving Jin a crown of flowers she had made, and saying that she loves Jin very much. This is seen through a vision by Tsubaki, and she immediately displayed jealousy towards Saya, screaming at her to get away from Jin.

Jin's hatred for Saya in all other timelines is likely caused by the Power of Order, which acts as an antithesis to beings such as Observers and Murakumo Units. The Power of Order requires absolute will, which just so happens to be present within Jin (and Hakumen by extension). Whereas Observers have the ability to alter or create phenomena, those with the Power of Order can reject and destroy phenomena. Noel Vermillion is one of the few people who can nullify the Power of Order.

Chronophantasma
Jin will be reunited with Tsubaki, in her new form.

Appearance
Jin is a good-looking and slender young man with short, stylish blond hair and green eyes. He wears the NOL major uniform with a black turtleneck and leggings under a white Japanese-style garment, white gloves, military boots, and a "jolting sapphire" colored jacket with a red lining and very long, detached sleeves.

When he was at the Military Academy, he wore glasses and the standard male school uniform.

As a child, he wore a light blue shirt and black shorts while he lived at the church. When he was adopted by Kisaragi's clan, he wore a Japanese tradition training shihakushō uniform.

Personality
Where his brother Ragna is hot-tempered and quick to draw first blood, Jin is cold, aloof, and borderline sociopathic. He cares little for the feelings of others, and denounces, in his own words, trivialities like camaraderie, believing that such things are lies that people use to their advantage. He has no compunction with killing anyone who gets in the way of his goal.

This, however, is all a façade. The moment he reunites with Ragna, Jin loses his calm, detached demeanor and reverts to his childhood self. His voice becomes noticeably more ecstatic, and he is now prone to fits of maniacal laughter, mostly due to Yukianesa's influence (which compels him to kill his brother due to his nature as the Black Beast, as well as the Power of Order, which perceives him as a threat to the stability of the world). In the past, Jin would often cling to Ragna for assistance with everything, which greatly annoyed him. It is also shown during the first time loop, that Jin loved his sister Saya as much as he did Ragna.

It is also shown that he was friends with his classmates, Carl Clover, Tsubaki Yayoi, and Makoto Nanaya during their time at the Academy (though he showed a noted uneasiness towards Noel, but treated her respectfully compared to his attitude towards her in the aftermath of the Ikaruga Civil War). In particular, he holds a genuine soft spot for Tsubaki, who was his only childhood friend after he was whisked away from his old life and adopted by the Kisaragi house of the Duodecim. The two share a long history together that is linked across the timelines.

Powers and Abilities
Jin proves his elite status in the Librarium with his exceptional skills on the battlefield. Wielding the Nox Nyctores named Mucro Algesco: Yukianesa, Jin controls the element of ice, wielding it with such efficiency that he is able to shape the ice he creates into different forms such as a series of blades and is able to propel himself on one. His swordsmanship as well as his powers rival and contrasts that of his brother Ragna. While Ragna fights with savage, powerful blows, Jin's style is elegant (although it should be noted that the damage output on Jin's attacks are considerably powerful like Ragna), which strangely polarizes his own personality affected by the Yukianesa. Since Jin and Hakumen are the same person, in Continuum Shift, Jin instinctively learns the 'Kokūjin: Yukikaze' technique at one point.

According to Jubei in Continuum Shift, Jin's true power is currently suppressed because of Yukianesa's influence on him. There are hints of this true power showing up periodically in the series, but not in its full potential. However, according to Ragna, should Jin's true power managed to overcome Yukianesa, then he said that Jin will become his "greatest enemy". This is also confirmed by Jubei.

Jin's Drive is Frost Bite. By harnessing the power of Yukianesa, Jin can encase his opponents in structures of ice, temporarily incapacitating them for a free hit. Unlike the other characters in the series (until "Chronophantasma", when Crush Trigger was introduced), Jin's Heat Gauge is broken up into four bars instead of the usual two the other have with the exception of Hakumen. His Drive attacks use one bar each, although they are incredibly potent as they deal multiple hits in one strike.

Trivia

 * A few of Jin's color palettes in Calamity Trigger references to the following characters:
 * Kanade Tachibana from Angel Beats!
 * Suigintō from Rozen Maiden
 * Louise Françoise from Zero no Tsukaima
 * Archer from Fate/Stay Night
 * Illyasviel von Einzbern from Fate/Stay Night
 * Hong Meiling from Touhou Project
 * Robo-Ky from Guilty Gear
 * A few of Jin's color palettes in Continuum Shift references to the following characters:
 * Lelouch vi Britannia (in his "Emperor" attire in R2) from Code Geass
 * C.C (in her appearance in R2) from Code Geass
 * Fatima the "Shadow Frost Witch" from Luminous Arc 2
 * Kaito from the Vocaloid programs.
 * Asuka Langley Soryu from Neon Genesis Evangelion
 * Jin is a very elegant and intelligent character, but he is very cold and hostile towards others. However, he can be very affectionate when it comes to Ragna. This caused the fanon to label him as a tsundere (a person who is initially cold and hostile towards another person (as well as sadistic), but beginning to show their warm side over time).
 * Arc System Works has recently released a Fan CD called "BlazBlue: Fan Disc Tsundere CD", with Jin as one of the two hosts.
 * Jin's seiyū, Tetsuya Kakihara, jokingly said in an interview, that Jin is actually not a tsundere, but a yandere. However, it could be stated that he can be a bit of both, with an added probability that he may also be a kūdere.
 * Intriguingly, when Ragna ends his Astral Finish he unfolds a black/red demonic wing from his left side. When Jin ends his Astral Finish, he unfolds a blue/yellow angelic wing from his right side.
 * Over the course of the events in Continuum Shift, Jin is revealed to slowly embrace a similar sense of justice and destiny with his alternate-self, going so far that he claims to be "The cold steel, which will restore balance to the world"; he also begins using an "Empty Air Array" stance as one of his Distortion Drives, and (much to Kokonoe's annoyance) starts to speak way too often.
 * Jin is one of two of the characters that are playable in the English version of the MMO Action Game, Lost Saga. The other character that is playable in the English version is Hazama.
 * Somewhat ironically, Jin's female version in the same game resembles Noel.
 * In a DLC for Calamity Trigger, Jin gains Ky Kiske's blue and white color palette. This returns as DLC for Continuum Shift, in addition to a Robo-Ky palette (with a metallic blue tone for the skin).
 * One of Jin's attacks, Musō Senshōzan, has been dubbed Ice Car by fans, and is commonly used in fan-comics, possibly due to the radio drama, where Jin makes the sounds of a car driving off at one point. Said attack creates a large icicle which Jin can use to ride across the screen, as well as hit opponents with it.
 * Jin's constant use of the word nii-san (brother in Japanese) and his fan-dubbed move Ice Car have caused fans come up with a joke going "What is Jin's favorite type of car? - A Nissan!", Nissan actually being a motor company.
 * The fact that Jin's birthday falls on Valentine's Day is ironic, since he outwardly expresses hate and indifference towards sentiments like love. However, it is subtly expressed that he does harbor such feelings for Tsubaki in Continuum Shift.
 * In contrast to his birthday, Tsubaki's is White Day (14 March).
 * In Ragna's story, Jin attempts to save him from Nu-13, but in his story it was revealed that he wants to save him so he can kill Ragna with his own hands.
 * Jin's unlimited form allows his ice attacks to be used at their full potential, with his D attacks being buffed incredibly and having new properties. Many of his special attacks also hit multiple times, increasing his damage. His Distortion Drive, Tōga Hyōjin, launches two ice waves instead of one, the animation of the second ice wave's launching is the same Jin have while using Rehhyō, Using Hiyoku Getsumei will deal more damage, adding a mini-version of Yukikaze, while Kokūjin: Yukikaze will happen even if it does not block.
 * Jin, along with Litchi, Noel and Tsubaki are the only characters in the series to use their clothing to strike their opponent.
 * Jin is also the only character so far in BlazBlue to sport EX moves (moves that require half of the meter needed to perform a Distortion Drive). These come in the form of Hishōgeki, Musō Tosshōgeki, and Hirensō, with Hizangeki being his most recent addition in Chronophantasma.
 * According to Ragna's story mode in Calamity Trigger, when Jin was younger he had a fear of the moon "falling".
 * Jin tries to run away from the moon in the bad ending of his story "Decision", if the player loses against Rachel.
 * When Tsubaki asked Jin whether he likes the moon, he answered that he hates the moon.
 * It is actually quite ironic that one of Jin's Distortion Drives, Hiyoku Getsumei, means "Ice Winged Moon Howl". Though to possibly inverse that, the move is aimed upward (as if Jin has the moon in his sight), possibly relating to the concept of "Fighting Fire with Fire."
 * While it is clearly stated that Jin hated Saya, in Nu-13's Story Mode, when Nu first encounters Jin, he treats her kindly and states that he was worried about both her and Ragna. When he hears that her name is Nu, however, he reverts to being cold, indicating that he may have been confusing her with Saya. Also, in the Wheel of Fortune Drama CD, they can be seen happily playing with one another. This may indicate that he does not hate Saya, his sister, of which all Murakumo Units are based on.
 * He also hates Noel because, as a replica of Saya, she bears a strong resemblance to her.
 * In most of Jin's omake appearances, he often tries to freeze people due to harsh comments, and in the Japanese scripts, he makes a reference to the Japanese name of his Astral Heat.
 * Jin is the only one who, between him, Ragna, and Saya, still has his blonde hair. However, as Hakumen, his hair has turned white/gray.
 * Due to the fact Kisaragi is his adoptive last name, Jin's full birth name remains unknown. The same applies to Ragna and Saya.
 * Much like the Murakumo Units, Hakumen and Jin have the same input for their Astral Heats.
 * Jin's power seems to vary differently in different media. In the Drama CD The Wheel of Fortune, he is much weaker than Ragna, but in the game, the two seems to be equal (Ragna is a little stronger, though it is also implied that he holds back whenever he fights against Jin) and in the Chimelical Complex manga, Ragna has to activate the Azure Grimoire to defeat Jin.
 * Jin is one of the two characters who do not "witness" Mu-12's birth in Continuum Shift's arcade mode, as his story ends when Hazama shows him a blue-eyed Noel. He does not have a still shot of him looking at Mu-12 descending like most characters have. Relius (having arrived after Mu-12's creation) is also another character who does not witness Mu-12's birth.
