Dark Elves are mythical creatures who can suck up magic just like breathing air. Resurrecting these Dark Elves... was Isuka's mission. Ikaruga rushes back to Isuka to stop her. She only has two wishes: stop the Dark Elf restoration, and to save her former friend and "family," Isuka! Meanwhile, Takeru finally awakens from the sedative Ikaruga fed him and meets up with Ouka and the girls, now freed. They head towards Ikaruga with over a hundred Dragoons in tow...
"I'm marrying Usagi because she's a precious commodity to me," says Reima. "I won't let you have Usagi," retorts Takeru. Meanwhile, Reima's scheme to become a "king" is well underway. There is a giant magic circle encompassing the campus, made of none other than witch hunt festival decorations. A mysterious shadow lurks around student council president, Nagaru.
In the chairman's office, Ouka finds files documenting Mari's crimes... The next day, the Mock Battle Tournament has entered the second round: Kyoya's 15th Platoon against Takeru's 35th. But during the battle, Yoshimizu, Kyoya's childhood friend and platoon member, has strange black thorns burst out of her body! "I've come to rescue you, my sweet Mari-san!" Emerging from the black thorns is the necromancer, Haunted.
