I watched Eiken on the basis of how incredibly ridiculous it looked. The exaggerated breasts of the characters had to be good for a few laughs. However, the show turned out to be more disappointing and borderline disturbing than I could imagine.
The show has a typical ecchi plot, with a newcomer at a Japanese high school trying to win over the girl of his dreams. What distinguishes Eiken from numerous other works is the massive size of its characters' chests. Never mind DDs-some of these girls go up to E or F cup sizes! They are more amusing than arousing to look at, at least for a few minutes.
The main problem is that the show over relies on having the characters fall into graphic sexual positions for its humor. The first time or two it's slightly amusing, but as the show becomes more graphic it becomes frankly icky, leaving the viewer with a dirty feeling more like one would get from a hentai. Particularly disgusting are the bits where they make food look like ejaculate.
Particularly disturbing is that all of this centers around minors. Even one of the prepubescent characters has massive breasts, lending the whole show a frankly creepy atmosphere. All in all, this show is best avoided, as literally the only good thing about it is the catchy theme tune.
