Kami nomi zo Shiru Sekai: Tenri-hen

Summer vacation should mean uninterrupted gaming for Keima Katsuragi, but the return of his shy childhood acquaintance Tenri Ayukawa ruins that plan. Tenri behaves strangely, and signs suggest that something supernatural is living inside her. Keima and Elsie initially treat the situation like another loose-soul capture, only to discover that the truth is connected to events from Keima's own past.

As dangerous pursuers close in, Tenri's hidden companion reveals a mystery larger than the usual conquest of a girl's heart. Keima has to revisit the day he and Tenri were trapped together years ago and understand why she remembers him so deeply, opening a path toward secrets that will reshape his role in the struggle between Heaven, Hell, and the human world.
