Long Summary Edit
In a restricted site, Yūji (one of Yamanaka's companions) attempts to open a room locked with seals, but Yamanaka stopped him before he could continue to do so. The trio begin walking away. However, the door opens slightly when Yūji looks back.
At Second Shibuyu High, Yu receives a love letter from the girl he saved from a vampire in the previous episode. She runs off before he can respond, but he pockets the letter. Shinoa teases him that he should build a relationship, but she is serious to explain that humanity must increase in numbers in order to survive in the world.
Moving on, Shinoa shows Yu her Cursed Gear, Shikama Dōji, which manifests as a large scythe. Yu is amazed by its power and asks Shinoa to give it to him. When she refuses, Yu decided to attack her in order to test the weapon's strength. She spars with him for a few seconds before completely overwhelming him.
Later, Yamanaka and his remaining friend chases down Yoichi, begging to become his disciples. Yu tells them to leave. He asks if they have to pride to beg from help from a person they used to bully until recently. Yamanaka begs because he thought that Yoichi (now part of the Vampire Extermination Unit) could save his friend Yūji, who went into the Forbidden Chamber and never came back. Shinoa replies that action will lead to severe punishment (even death) and tells them to give up.
Regardless, Yu, Shinoa and Yoichi go to the chamber. Shinoa warns Yu not to try anything dangerous, but Yu rushes in anyway and tries to seize the cursed axe from Yūji (now controlled by a demon). When Yu grasps it, he suddenly finds himself back in Sanguinem with Mika, Akane and the other orphans. The orphans asked Yu to continue with their dinner, but Yu feels uneasy and confused. He says he thought they died. Mika and the others reply that they are dead, and ask Yu to avenge their deaths. However, Yu says Mika would not want that and demands that the demon show its true colors and stop pretending to be his family.
Yu wakes up, realizing that the demon had attempted to possess him. To Shinoa's surprise, Yu managed to expel the demon just by his sheer will. Since Yu has what it takes to handle Cursed Gear, Shinoa says she will tell Guren and he may soon let him into the training class, even though the course already began.
In Sanguinem, Ferid, who is still alive, struts down the hall to where he slaughtered the Hyakuya orphans. He cheerfully sings out alterations of Mika's name and approaches a figure dressed in the vampire soldier uniform. He says that Yu is being kept by the Japanese Imperial Demon Army. When Ferid approaches, the figure turns and draws his sword, remaining silent while he points it at Ferid's neck. The figure is revealed to be an older Mikaela Hyakuya. He glares at Ferid and his mouth opens slightly to reveal fangs.
