Synopsis of Bishounen Tanteidan
Mayumi Dojima, a sophomore at the exclusive Yubiwa High Academy, has lost something: a star she glimpsed only once, ten long years ago. But help is on the way, in the form of the unofficial, secret, and completely mysterious Handsome Boys and Detective Club! Rumor has it that they solve problems within the school (which they are said to have created) for aesthetic rather than financial reasons, these five beautiful boys take Mayumi into the world of excitement, danger, and overwhelming beauty of hers.
