If there's only one big boob anime you see this year, make it Eiken! This extremely well animated and light hearted series is the final word in huge breast anime! There isn't a single scene that doesn't involve at least one girl with basketball-sized tits that bounce wildly around like they have a mind of their own.

The story involves a shy high school boy, Mifune Densuke, who is forced to join the Eiken squad, a club of inhumanly well built female students. It doesn't hurt that Mifune's dream girl, the "88cm f-cup" Shinonome Chiharu, is part of that group. Mifune notes how Chiharu's chest continues to grow in size every day. In the first episode alone Chiharu's bra snaps open once and bursts open on another occasion. To top it off, there are two other girls in the Eiken club that are even larger than Chiharu!
