Koyanagi reveals she is a former classmate of Elena's. Shuichi scents Chihiru's wallet with Subaru and decides to get it back as it contains Chihiru's address. Claire learns Shuichi left with Chihiru and insists on finding him, so Koyanagi sends their fighter, Yota, with her. Shuichi is found by Subaru, who reveals his power to summon a giant monster with two heads, and crushes them. Yota asks Claire out but she refuses, claiming Shuichi is her other half, hinting at her feelings for him. Shuichi and Chihiru, regretting their weaknesses, somehow fuse their broken bodies into a single monster fuelled by rage. Subaru is forced to summon his monster to save himself while Shuichi and Chihiru lose their individual selves and fuse into a single personality. They get past Subaru's defences and almost shoot him with the twin pistols replacing Shuichi's revolver, but the fight is stopped by Elena. Shuichi desperately wants to attack Elena, but Chihiru gains access to a memory Shuichi has apparently forgotten of Elena as a human, jarring her back to herself. With their minds separated their body falls unconscious. Elena has a flashback to meeting the alien, who is becoming more interested in humans and wonders if he has spent too long in a human body. Subaru tries to stand up to Elena but it is clear he is still intimidated by her. Claire and Yota find Shuichi and Chihiru unconscious and returned to their separate bodies.
