Tsubaki Yayoi

Tsubaki Yayoi is Jin Kisaragi's childhood friend, Noel Vermillion's former roommate from the Military Academy, and a member of the non-official Novus Orbis Librarium's Zero Squadron. She originally appeared as a non-playable character in the story mode of BlazBlue: Calamity Trigger, but starting with BlazBlue: Continuum Shift, she became a playable character.

Information
During her time in the Military Academy, she was close friends with Noel and Makoto Nanaya. She is described as a straight A student, and has a rather no-nonsense personality. She is very serious and reserved, and is a member of the dignified Yayoi family. By the end of BlazBlue: Calamity Trigger's True Ending, she is assigned by Hazama to kill Noel and Jin. In BlazBlue: Continuum Shift, Tsubaki heads to the 13th Hierarchical City of Kagutsuchi to search for Jin and Noel. Unbeknownst to Tsubaki, Hazama is just using her to gauge Jin's Power of Order, and to push Noel further into becoming Mu-12.

Continuum Shift
She uses an Ars Armagus called Sealed Weapon Izayoi. When Tsubaki found Jin, he told her to get rid of Izayoi because it "steals the light from the user's eyes", implying it would, after a certain period of time, cause her to go blind.

Tsubaki is revealed to be a fan of Hakumen, going so far as to own all the books and movies based on the exploits of the Six Heroes. In Hakumen's Story Mode, he indirectly reveals that in the past she had been his secretary instead of Noel. While they had more time together, he ultimately neglected her for his own exploits. She pleaded for him to stay when he had left, but continued on, and she was killed as a result. To remember the mistake he had made, he named one of his attacks in her honor. After her fight with Noel, Hazama tells Tsubaki that because of Noel's continued presence, she took Tsubaki's place as Jin's secretary, relegating Tsubaki herself into assassination tasks. Tsubaki, already slowly losing her sight due to overuse of Izayoi becomes depressed and angry at Noel, believing she stole everything from her (though Hazama left out that Tsubaki would have died anyway in the timeline where she is with Jin). Hazama uses the surfacing of these emotions to his advantage by having Phantom use its sorcery on Tsubaki to manipulate her jealousy for his own purposes. The critical point of her jealousy is reached when she pleads Jin to back down, telling him that she only wanted to be with him, and wishes Noel were dead. Ultimately rejected by Jin, Tsubaki sides with Hazama and the Imperator as her eyes turn red and her white clothes become black.

In her true ending, she has the opportunity to kill Noel, but finds she cannot bring herself to do it, and is confused as to which side she is on. Adding further to her distress, she has completely lost her sight due to the Izayoi.

Chronophantasma
Roughly one month after the events in Kagutsuchi, Tsubaki has been promoted to Major for fending off Ragna the Bloodedge's terrorist assault. She patrols Ikaruga searching for enemies, while still being confused in her decision to serve the Imperator. In her Arcade ending, during the battle with Jin, Mind Eater, the spell the Imperator placed on her goes berserk, causing her to half wanting to kill Jin, half asking him for help. Jin tries to save her but the Imperator somehow interferes. Tsubaki then awakens as Izayoi, with new powers and fresh determination to destroy all the "evil" that oppose the Imperator.

Personality
Tsubaki is a serious, mature, and intelligent person. She has always followed her orders from the NOL and has complete faith in them (likely to honor her family name). She has always had a childhood crush on Jin, and deeply loves and cares about him. She was also good friends with Noel, Makoto and Carl Clover when they were at Military Academy. However, when Hazama told Tsubaki about the alternative timeline where she was always with Jin as his secretary and how Noel usurped that position away from her, she becomes extremely jealous. She begins to harbor a hatred toward her best friend that, once manipulated by Phantom's sorcery, evolves into a desire to kill her in order to be with Jin. Even after changing sides, she still respects Hakumen despite sharing different views.

In BlazBlue: Chronophantasma, Tsubaki's personality has almost been completely overwritten by the effects of Ruby: Mind Eater, the spell that Phantom cast on her in order to allow the Imperator to control her directly. Her devotion to the NOL has been taken to its greatest extreme, and she is now little more than a mindless drone who lives to carry out any and all of the Imperators orders, including killing her own friends. When Jin confronts her, however, she shows signs of resistance due to her feelings for him.

Appearance
Tsubaki is a young woman with long red hair and blue eyes. She wears an white cloak with an eagle eye mask to cover her face. When she is in battle, she wears the Izayoi hat, a Japanese-style military uniform, and black military boots.

When she is under the influence of Phantom's magic, her eyes turn red and her entire uniform becomes black. This change carries over in Chronophantasma.

When not on a mission as a member of the Zero Squadron, she wears a white cloak and black tights with her white military boots. Her hair is hidden under her white beret as well as under her cloak.

When she was in the Military Academy, she wore a blue headband with her standard uniform, except that she wears a longer skirt, black pantyhose, and brown leather boots.

When she was a child, she had short hair kept in a bob cut, and wore a bright, pink kimono with flower patterns.

Powers and Abilities
Tsubaki's fighting style is an interesting interpretation of the standard "sword and shield" style of traditional Western swordplay, where her oddly shaped, floating book acts as a small buckler shield. Tsubaki's short sword is capable of adopting a variety of shapes, sometimes as appearing as a fencing foil, a whip sword, a floating claymore or even a staff. Her book, similarly, can change its form. Lights and angelic imagery feature prominently in Tsubaki's fighting style, such as wings and feathers appearing around her for various attacks. Because of how her Drive works, her style is punctuated by moments of gathering light energy before rushing down opponents with long protracted combination attacks.

Trivia

 * Tsubaki's birthday, March 14, falls on the same day as White Day in Japan, South Korea, Taiwan and China which is an mirror equivalent to Valentine's Day where girls respond to boys who gave them gifts on the said holiday. This reflects her relationship with Jin, as his birthday is Valentine's Day.
 * Interestingly, in the drama track The Wheel of Fortune, it is revealed that Tsubaki actually loves chocolate so much, that Jin advised her that it was harmful for her health.
 * "Tsubaki" means "Camellia" in English, a camellia is a huge beautiful flower that has no scent and wilts easily.
 * Incidentally, the Lyrical Version of Condemnation Wings is called "Cry Camellia".
 * In Japanese flower symbology, red, yellow and white Camellia represents "in love", "longing" and "waiting". This is reflected in her default color scheme and her personality.
 * Her seiyū, Asami Imai, is regularly a part of BlazBlue Radio, along with Kanako Kondō and Tomozaku Sugita.
 * Tsubaki's Astral Heat uses what appears to be the statue located in the Cathedral. However, in Chronophantasma, the statue is black, reflecting Tsubaki's corruption.
 * In Taokaka's gag reel, Tsubaki admits to having a secret "fetish" for period adventures, even going so far as introducing herself as Robin Hood to Carl.
 * During her gag ending in Continuum Shift, Tsubaki admits that she hates pandas upon seeing the panda (Lao Jiu) in Litchi Faye-Ling's hair. The reason for this is unknown. Strangely, she is extremely gullible in the gag ending, as she even believes that Litchi (who at the time was drunk) had been taken over by Lao Jiu and gets 'coerced' into cosplaying and getting a new Peking duck.
 * The name of Tsubaki's Armagus, Izayoi, means "sixteen-day-old moon" in Japanese. A sixteen-day-old moon has just passed its fullest phase, so it is at this point that its brightness begins to decline. This is another clear reference to Izayoi's blindness-inducing nature.
 * Tsubaki Yayoi (Name, alternate).pngn the game's files, mainly the images for character name graphics from places like the selection screens, a file for a name Tubaki Yayoi is found. This is a common mistake Japanese people make when romanizing the tsu sound due to using an outdated transliteration method.
 * Gameplay of Tubaki exists, namely in this video. Her art appears to be story mode art of a possibly unused Noel donning Nu's armor. She is most likely the beta version of Mu-12, considering her crest is the same, and her in-game sprite (and only sprite) is a static Nu-13 recolor with "MU" scribbled on it.
 * Some of her special moves bear names from movements/chants for a Requiem Mass.
 * All of her special moves have Latin phrases for names.
 * According to Mu-12's winquote against Tsubaki in Continuum Shift II, the Izayoi's side effect has already affected 65% of Tsubaki.
 * Her surname Yayoi means march (the month of her birthday), life (maybe a reference of her death by her weapon) and extensive (a reference of her overuse of Izayoi).
 * All of Tsubaki's Special Moves can be done with all the Command Buttons (A, B, C, D) except for Confutatis Maledictis which can be done only with C and D, Macto Maledictis only with D, and Requiem Aeternam only with C. This is no longer the case in Chronophantasma.
 * When she became corrupted by Phantom's magic, her black clothes have silver/white highlights and a green ribbon tying her corset in Continuum Shift. However, her artwork for Chronophantasma shows her with her original gold/yellow highlights and red ribbon.
 * There is a piano remixed version of her theme, Condemnation Wings, used exclusively in the drama track The Wheel of Fortune. This version is yet to be released.
 * There is a bug in Carl's scenario in which when Tsubaki appears, she will have no mask and when Carl starts talking, the mask pops out on Tsubaki's face, to be removed right after.
 * Tsubaki and Noel are the only characters in the BlazBlue series with playable alternate forms. In Tsubaki's case, Izayoi serves this role.
 * When Amane Nishiki uses his Astral Heat on Tsubaki, she has red eyes, despite hers being originally blue.
