Summary
Hyoudou Issei was having a crisis over Yuuto Kiba being his type to a T. As a girl, at least. He couldn’t feel that way towards a guy, not with all the women in his ever-growing harem! But maybe, just maybe, that was just the start of Issei seeing Kiba as more than just his best friend.

Summary
Sun Jing was an ordinary high school girl-quiet, serious, and seemingly responsible-until a freak accident in her bathtub ended her life. She wakes up in an unfamiliar world, one that looks like an anime she's only ever heard about: Highschool DxD. Except she's never watched it, knows nothing about and desperately wants to go home.
To make matters worse, a mysterious "System" has attached itself to her, offering guidance-but often in confusing, cryptic, or downright dangerous ways and giving her strange quests.
"This isn't good. This isn't good at all. I'd like to go back home, actually."

Summary
The Twink Club is a longstanding group of the finest young people around, all of them possessed with the prettiest faces and the most disproportionately huge cocks! Though they are constantly being hounded by unfair teachers and council members who accuse them of doing nothing but sitting around and jerking off all day, they always manage to argue their case. Their main argument does tend to be that anyone with dicks as big as theirs can do whatever they want, but few women are willing to argue with this very obvious fact.
