Character

Nu-13

She was programmed to terminate anyone she deems as hostile subjects that came near the Gate. Nu-13 is also shown to have a split personality, split between an emotionless girl when around others, and a yandere when around Ragna the Bloodedge, though this may be how she was programmed to act. Nu-13 wants to absorb Ragna and have him join her in destroying the world, because she, too, possesses a piece of the Azure Grimoire (although neither she nor Ragna realized the pieces they possess were actually imitations). When Ragna refuses to join her, she decides to take him by force. She also knows Hakumen, recognizing him as a "Sankishin Unit". Birthday: December 31
