Thanks to a chance encounter with the brilliant, beautiful, busty, but extremely shy Chiharu Shinonome, Eiken: Eikenbu yori Ai wo Komete sees Densuke being forcibly invited to join the mysterious Eiken Club. Led by Kirika Misono, she recruited Densuke both for his completely boring, unassuming nature and his completely accidental groping of Chiharu’s chest.

Densuke needs to act fast if he wants to find his way back into Chiharu’s good graces. A beauty like her doesn’t go unnoticed, and he may very well find that he’s not the only one trying to win Chiharu’s heart.
