Μ-No.12-

""I've arrived. Reborn as Kusanagi. The destroyer of all living creatures. I am death...""

μ-No.12-, commonly abbreviated as Mu-12 and known as both Kusanagi and the Sword of the Godslayer is a Boundary Interface Prime Field Device, Murakumo Unit, and the alter form of Noel Vermillion. Originally birthed in the 5th Hierarchical City of Ibukido, Mu was a depressed and murderous Prime Field that remained as a repressed part of Noel's soul. This part of her has disappeared with time, and her powers are used by Noel in times of need.

Mu first appeared as the final boss of BlazBlue: Continuum Shift, being unlocked once the true ending of story mode is completed.

Appearance
Mu-12 is physically identical to her original form, Noel Vermillion. In BlazBlue: Continuum Shift, her eyes have dilated pupils and are sometimes depicted as glowing a bright blue, but this trait disappears in the next two games.

When out of combat, Mu wears a cloak very similar to Nu's, but with a large blue jewel and harness attached to a small metal collar in place of Nu's much larger collar. Her jumpsuit is white, has slightly larger gloves, exposes her lower torso, and lacks pants, which she replaces with long white leggings. Her jumpsuit also has glowing blue jewels set in golden frames on her hips, which are also present on top of her leggings. The metal piece over her crotch is similarly golden. In place of Nu's seithr regulator, Mu wears a metal headpiece with her variant of the Prime Field Device symbol engraved into it and stiff, horn-like antennae, an article of clothing which she continues wearing in combat.

Mu's battle gear is similar to a mecha, just like her “sisters”, but with several key differences. She lacks a bodysuit, instead wearing a small blue, gold, and black garment which only covers the sides of her torso, her hips, and her crotch, exposing her back and front. Her gear has enormous blue and white shoulderpads with seithr regulators built into them, as well as a third, smaller regulator built into a gray metal object on the back of her neck. Under the shoulderpads, she wears a collar similar to that of a dress shirt, with a short red necktie. She has long blue gloves with golden metal guards on the hands, and metal mounts on her forearms for her blades, identical to Nu's and Lambda's. Her bladed leg armor is also identical to theirs.

Personality
"Although she appears calm and collected, she is actually quite lonely. Moreover, she is shy, and is bad at forming close personal relationships. She is good at fighting, but outside of that she is unskilled. Her cooking boasts the ability to kill people."
