贖罪の教室 BAD END

Mikimoto has everything it takes to become a top-rank journalist, but a journalist can't go without a good scandal to write about. Developing his own personal underground newspaper, Mikimoto makes his fellow male students angry and lustful all towards one person: the voluptuous Nanase. When his classmates finally go after her to punish her for all of her "sins," Mikimoto records every depraved moment. As the popularity of the newspaper spreads, more and more girls become prey to the perverse desires of those influenced by it. Even Mikimoto is finding it hard to resist his own dark desires towards one specific well rounded beauty, Madoka.
