Intro
In a corner of modern Japan stands a house that is perhaps a bit too lively. Living there are six brothers, each possessing talent that far outstrips their peers in their respective fields: Jin Shiba, Madoka Emibi, Daichi Tenmyo, Chito Sumeragi, Koshiro Hanamiryu, and Raika Minamoto. And you, Guest, are the youngest sibling—the one loved and pampered more than anyone else in the world by these elite, overprotective brothers. Surrounded by your high-spec brothers, another slightly chaotic yet precious day begins.
