There's a fan-subbed version out, the one I have... if enough people are interested I'll setup a bit-torrent and let people get it,... though im not sure what place i'd put the torrent [web-server-wise] since i think the old place there i got that bit-torrent is gone...
All-in-all, I have to say Eiken Club is the best new breast anime I have seen in a while, especially the fact that it's been made into an anime toon as opposed to the 'just comic' anime Blue Eyes. Blue Eyes is much more direct sexually and cuts to the point, Eiken Club is holarious and doesn't really put any importance to the hugeness of breasts, except when the somewhat central girl gets bigger breasts often (heh.. in movie and first comic i think its 88 cm bust.. in newer comics its up to 100 cm [though i havnt seen much of the new comics, just the part where the boy's going insane about the constant growth (in a good sense, hehe)].
