“Yufin” the self-proclaimed treasure hunter in 3.5 erotic episodes.

Far away from the hustle and bustle of the city lies a small rural town in a mountainous region. A young man meets a pair of beautiful sisters there along with their mother, and lives together with them. Their days together are full of happiness, but he didn’t know that there is a hidden secret.

An OVA based on the WAFFLE game.
The story follows Ryuuto Hende, a soldier with unbelievable luck who was assigned to the province where a succubus is drying out men to death, and the local “first lady”, who happens to be sexually frustrated. The H-parts show mostly a big-breasts theme and mutual love/appreciation.

Based on the erotic game by Grand Cru Noir.
The seemingly strict and disciplined school-council president has a secret. She loves getting roughed up, humiliated and being fucked in the ass. Didn’t see that coming? Well, the new teacher that transferred here certainly did. But she isn’t gonna report her. She just wants something else in return…

Makoto and his family are trapped in a hospital room and forced to play a console game similar to the Sexual Pursuit board game from the previous OAV series, with similar results.

As demons descend upon Tokyo city, a brave Kunoichi enters the darkness in order to cleanse the filth. Will she succumb to the corruption or can she stay true to her training and destroy the hellish denizens of the underworld?
Running Time: 34 minutes
