Oppai Tensai = Genius of Breasts
BUSTing out in Winter 2009!


Have you ever watched an anime, read a manga, or played a game, and wondered to yourself:

"Gee, which girl has the biggest chest?"


Then you're just odd.

For the rest of us, that is the sole purpose of Oppai Tensai - to categorize and sort all your favorite female characters according to their chest size. No longer will fans be in doubt whether one character is bigger than another, or if another character can be considered loli. No show, manga, or game will escape our scrutinizing eyes - Oppai Tensai will be THE "Valley of the Gods".
