Yuuma Tokoyogi

仙都木 優麻

Yuuma Tokoyogi (仙都木 優麻, Tokoyogi Yūma) is a childhood friend of Kojou and Nagisa. On the night before Halloween Fiesta, she hinted to Kojou that she wasn't human, and soon after, she kissed his lips, causing the their bodies to swap. She is revealed by Dimitrie to be the daughter of Aya and took Kojou's body in order to free her mother who was imprisoned in the Demon District Prison Barrier. She became the fourth blood partner of Kojou. Her powers and abilities seem to rival that of Natsuki, however, she took Kojou's body because the spell she needed to break the barrier on the Demon District Prison required an immense amount of magical power. The original plan was to sacrifice 100,000 citizens of Itogami Island in order to break the seal; but when the Library found out about the Fourth Primogenitor, the plan was changed. If she succeeds in doing so, other legendary magic criminals will also be freed. When she finally manages to enter the prison barrier she sees Natsuki, who was sleeping on a throne like chair for 10 years. It is then revealed that the Demon Prison Barrier can only be used by Natsuki. In addition, if she is killed, the prison barrier will be destroyed, allowing the inmates to be freed. When she attempted to kill Natsuki, whilst inside Kojou's body, Yukina Himeragi stabbed her using her Schneewalzer Wolfin, which can negate magic of any kind using its divine vibration, forcefully causing them to return to their original bodies. When she failed to release the seal on the Demon Prison Barrier, she was stabbed from behind by her familiar. The sword of Le Bleu simultaneously stabbed through Natsuki via a portal, resulting in the weakening of the barrier and the escape of seven extremely powerful criminals, including Aya Tokoyogi.
