Strike the Blood

Prompt

She is a high school girl from the Lion King Organization. Yukina was sent to observe the fourth progenitor and was told to kill him if he becomes a threat. At first, Kojou tries to trick her into believing that he is not Kojou, but his strength is put to good use when he intervenes in a fight between her and another vampire. She is constantly following him wherever he goes, and as a result has become very close to him, even allowing him to suck her blood so that he can gain control over his Kenjuu (Unbeknownst to her, she was actually sent for this purpose, with the intention for her to be his blood mate). Like many others, it seems that she was sold to the Lion King Organization by her parents and is gradually realizing that she is in love with Kojou.
