"Disgusting, not even cute." I hurt my little brother, a popular cross-dressing model, with heartless words. But none of them are true. Our parents remarried when we were little, and Yuki became my step brother. He's so cute and very, dearly important to me, but somehow my feelings changed into something they shouldn’t have. It's painful to be around him, but Yuki, who's grown up to be so handsome, keeps coming to me even when I give him the cold shoulder…

From MangaHelpers:

Shun knew what to expect when he became a high-school student. As he entered the gates of his new school, four beautiful girls suddenly surround him. These four girls are the same four girls he grew up with since kindergarten. The four girls are Rio the athlete, Miku the cook, Nana the nerd, and Yuri the student president. These four girls will be battling it out between them in order to win the heart of their beloved Shun.

The story is set at Shishidou, a school attended by rich and elite people. Tomu Shirasagi, a gambler, is a mysterious new transfer student who has come from a public school (instead of a prestigious private one) and faces the elitist environment. There, he declares a challenge toward any student and claims he will bring to the ruin the whole school through a series of gambling matches. Nobody knows why he has come to that school or what the real motivations behind his actions are.
During any match, Tomu shows off all of his unique coolness and ability.
He employs a wide range of tricks, both psychological and physical, to ensure his victory. In any game, you will constantly ask how he's planning to win, why he's really doing certain things, and what's really going on. At the end of the matches, the tricks are revealed, and they all work in real life, even if they do require one to be highly skilled or lucky in order to perform them.
The story centers around the various matches he undertakes and the interactions between the various characters, like Mika Shishidou, the beautiful granddaughter of the school headmaster, who is highly intelligent but contemptuous and superb, or Abidani, the vampiric looking dorm superintendent and main villain (for now) in the series, who has a sadistic personality and whose goal is to make Tomu leave his school (or to get him killed).
As the story unfolds, more about Tomu's past is revealed, leading to unpredictable turns of events.
