Yukio sets out to the school's Exorcist-only shop to stock on some supplies along with Rin. There they find that the owner's daughter, Shiemi Moriyama, is being afflicted by a demon that dwells in her family's garden and, to save her life, they confront it by themselves.

Suguro's joint strategy pays off, and the Exwires have success in their sights! But then a gigantic moth demon (cuchi) appears, and attacks Rin the moment he lets his guard down!
