Biography

Central Fiction

Cast into the Embryo, Nu’s memories were changed so that she believed it was 12/31/2199. She also became one of the chosen. She woke up in Kagutsuchi near the cauldron, being awoken by Noel. Despite being knocked to the floor, she continued her assault, only being stopped by Ragna. She lost to him, something she didn’t think possible, but instead of killing her, the Grim Reaper offered to save her, only being unable to as he was teleported away by Nine the Phantom. She was transported to Ikaruga and told by Nine to kill Izanami so she could claim her piece of the Azure and have her wishes come true. Relius had also ordered her to start hunting for the Nox Nyctores’ and began with the Arma Reboare: Muchourin, finding Platinum the Trinity but being able to keep track of her due to the latter’s fluctuating existence.

She later found Bang Shishigami, the wielder of the Phoenix: Rettenjou and began fighting him until she was interrupted by Nine. She fought back against both, insanely muttering that the Nox was hers and hers alone; despite this, Bang still managed to flee. While searching for the ninja, she was attacked by Arakune who wanted her Murakumo. She was saved by Relius, who conducted repairs on her, and she allowed it. Nu later followed Izanami into Nine’s workshop and nearly assaulted the witch had she not been stopped by Jubei. The two fought until the Corpus Sepulcro: Requiem froze the area in space-time.

When Nu awoke, she was still fighting Jubei, although this time above ground and near the Amaterasu Unit. Intent on destroying it, she fought Jubei and then eventually both Hakumen and Izayoi. She beat the both of them, only being stopped by Ragna, who she revealed to that she had absorbed the core of Gigant: Take-Mikazuchi. When defeated, Nu was knocked unconscious but was forced to awaken by Terumi who sent her insane and broke her soul. Nu lashed out, nearly killing Tsubaki, a blow that was defended by Hakumen – she fought the leader of the Six Heroes, being not only defeated, but knocked unconscious. She was watched over by Tsubaki and Jubei until all three of them dissolved into seithr.

In the new world created by Ragna, Nu was left in a catatonic state. She now lives bedridden inside a church with Noel and Lambda as her carers.
