Ep. 4: Akina confronta a Enjin mientras descubre que el alma de Gin permanece dentro de su cuerpo.

4

Akina and Hime discuss Enjin's possession of Gin Nanami, Ao's brother, with Yuuhi, who claims that Gin's soul is likely destroyed. Elsewhere, Enjin realizes that he cannot use his full power because Gin's soul is still present in his body. Ao and Touka Kishi, Kyousuke's sister, prepare food for Hime on her business trip. When Akina searches for headphones for Hime, he finds a monkey statue that he won in a yakisoba-eating contest with Gin and Hime. That evening, Enjin attacks the barrier created by the Seven Pillars and passes through it. His associate, Eiji Shinozuka, is confronted by Kotoha, Ao, and Yuuhi, who realizes that Shinozuka is a hanyou like Kotoha. Akina confronts Enjin, but is unwilling to use tuning on him after Enjin reveals that Gin's soul is still present in his body. Akina is saved by Yae Shinatsuhiko, Yūhi's sister, and Enjin retreats.
