Succubus moves in with a guy to study the detrimental effects of sucking energy out of young men. Except, he's part of a control group of twins -- one twin will have their energy sucked daily for 15 years, the other will never be allowed to orgasm. Guess which one our hero is? Complication: His bluntly honest demeanor is a huge turn on to his succubus handler.

“Mashino! Don't get your panties in a bunch!”
From Kawasaki Tadataka, author of Chio-chan no Tsuugakuro, comes the story of a girl with a brand-new magical power.

A twitter doujin about a couple who are so close and yet so far.

Chio-chan is a gamer and a high school girl who gets into some interesting predicaments on her way to school. For instance, she was once running late for class due to staying up all night playing a game like Assassin's Creed, and her usual route was blocked. Prompted by the previous night's gaming, she decided to take to the rooftops, a strategy that does not work quite as well in real life! She also faces more mundane difficulties, like awkwardness in interacting with a friendly acquaintance met by chance on the way to school. Join Chio on her funny and unusual daily journeys to get from home to school on time.
