Izayoi

Izayoi is the true form of the Sealed Weapon Izayoi that has taken over Tsubaki Yayoi, and a playable character starting in BlazBlue: Chronophantasma.

Information
Izayoi is the form Tsubaki undertakes after the spell the Imperator placed on her forces her to unleash the full power of the Sealed Weapon Izayoi. The spell ends up being broken by Jin Kisaragi, but how she is freed is not revealed. Turning away from the darkness of the past, she now takes up her sword to punish all crimes and seek out the true light. After a battle with Makoto Nanaya, Tsubaki somehow regains herself once more, but feels lost as now she knows the Imperator's justice is a lie. However, with the support of Hakumen and Noel Vermillion in her true form, taking up her sword once more, she decides to fight for the justice she believes in and for the friends she cherishes.

Personality
Izayoi is shown to retain Tsubaki's desire for justice, but her awakening is under a much more sinister light. She believes that the Imperator and the NOL are not to be defied, and that she is the Sword of the Imperator herself, and gives Noel, Makoto and Jin death sentences. She also refers to herself as the true light.

Once freed from the Imperator's spell, and after battling Makoto, Tsubaki becomes lost and confused because the "justice" that she has lived by her whole life was all a lie. On her journey to discover the true meaning of justice, she discards all personal biases when judging others, even her own friends.

Appearance
Using Tsubaki's form, Izayoi's physical appearance remains the same, with the exception of her red hair being tied into a ponytail. Her appearance is a mix of Tsubaki's former Astral Heat and her NOL uniform, her armor being a sleeveless, black, skin-tight bodysuit with a short, slender, white outfit, and white, knee-length boots. The armor bears a slight resemblance to the armor worn by the Murakumo Units, but with two shields floating around her instead of swords, and an overall less revealing outfit.

Powers and Abilities
Being the true form of the Sealed Weapon Izayoi; Izayoi is an incredibly powerful being who is the sole person able to kill Observers. Her power is so great, that it took the combined efforts of a Beastkin, the Eye of the Azure and someone with the Power of Order, just to bring her down. As well as this, her ability 'Immortal Breaker' is capable of killing any immortal being due to the fact that the Sealed Weapon was designed to target Observers. As a prototype Murakumo Unit, she is relatively on par with the Units themselves in combat(based on her battle with Noel Vermillion).

However, one drawback to her 'Immortal Breaker' is that it is incapable of killing beings who possess the Power of Order, like Hakumen and Jin Kisaragi.

Etymology
The word Izayoi means "sixteen-day-old moon" in Japanese. In astronomy, 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 an extremely clear reference to the Sealed Weapon Izayoi's power to induce blindess upon its wielder, namely Tsubaki.

Trivia

 * Nearly all of Izayoi's moves are references to the Gundam series, in particular Gundam 00 (Gundam Astraea, Seraphim Gundam, Trans-Am System) and Gundam Seed/Gundam Seed Destiny (Freedom Gundam, Destiny Gundam, Justice Gundam, Strike Gundam, Aegis Gundam, Strike Noir Gundam, Gundam Astray Mirage Frame).
