Usagawa Rinne, a normal female high-school student, was spending happy days with her lover, Sakaki Guryuu. However, the peaceful days shattered suddenly on the night of Sakaki’s birthday. Sakaki witnessed Rinne getting killed, her eyeball gouged by a girl called, “Gankyuu Eguriko,” as well as having witnessed Rinne revive as if nothing had happened. To the shocked Sakaki and confused Rinne, Gankyuu Eguriko speaks of an “Eden’s Apple.”

Old LN from 2005, by the author of the slightly more popular work “Sasami-san @ Ganbaranai”.
The illustrations quality kinda suck but I couldn’t find any digital rip of this series so I went with what the Baka-Tsuki editors posted.
Epub for volume 1 was stolen from some place idk, it has hyperlinked tlnotes and cool stuff, the others are just baka tsuki scrapes.
