Yuki is continually haunted by visions of blood. Nevertheless, she is determined to find out about her past from Kaname, but he repeatedly evades her question. Zero sees Yuki looking troubled and goes to the Moon Dormitory by himself.

In order to protect the academy, the Headmaster confronts the head of the Hunter Society while Rido is still on the rampage. In the meantime, Ichiru pays a visit to Zero and shoots him with the Bloody Rose gun.
