One day a girl named Koyori Fujimoto is pulled out of a crowd while watching a magic act on the street and is forced to participate by getting into the 'Miracle box' and being made to 'disappear'. What really happens is she suddenly finds herself being carried over the shoulder by someone, down a ladder into the sewer below the street. Turns out the guy is part of the magical act. When Koyori gets a good look him, she is stunned at how good looking he is, and by his one brilliant emerald eye, and other brown eye. Koyori is fascinated by him and asks his name, and he tells her it's 'Yuki' and then he rides off on his motorcycle. At school the next day, Koyori is preoccupied by thoughts of Yuki, but she also catches a few glimpses of an old crush, Shuu-kun. We see that Koyori's class is taught by a very geeky looking guy with glasses named Nagase-sensei, but turns out he is Yuki!! Now Koyori is caught in the middle between her feelings for her classmate Shuu-kun, and her new feelings towards her surprisingly handsome teacher.

The aphrodisiac night retreat is a place with no menu, and the tea is made by the employees to fit the customer's image. An omnibus story surrounds the overbearing masters, various customers, and the tea!

Iizuka Sono just transferred to a new school where the reigning oddballs have their own club called "BxB Brothers" ("B" for "Baka" = "Idiot"). According to them, you make your life meaningful by doing things out of the ordinary. While Kazuhisa and Kei aren't too selective about membership, Katsumi is – so it's just the three of them… Until Sono strikes Katsumi as an admirably unusual person, and he coerces her into becoming a Brother! The more Sono learns about the Brothership and Katsumi, the more pride she takes in being a Brother, but being the only BxB Sister has its problems. Caught between the open affection of Kazuhisa and the reserved admiration of Katsumi (with Kei taking school-wide bets on the side), all while struggling to register the club officially, it's a BxB Triangle that constantly takes on new angles!
