Because For Some Reason My Big Brother Doesn't Like Me At All--!! 01
Nao's brother complex is so strong, it's almost at the point of incest. She's determined to make her brother Shuusuke see her as a woman. So determined, that she goes as far as going into his room to throw away all his non-incest related porn.

Comedy.

Based upon the designs of a yucky loli manga where the body proportions are completely off, even worse than CLAMP.
For the fans of that kind of stuff.
