So far, there are about nine volumes? I think they're only in Japanese so far, but we know that the sixth one will be released in english sometime this year. Anyhoo, I was searching for some information about the volumes, strolling through sites, taking quick peeks.... when I suddenly saw the cover for VOLUME 12!! WHOOHOO!!!!! I don't know if it's fake (and I'm desperately hoping that it's not) but I swear the art was exactly like how the author draws it. If I remember correctly, it was with Utsuho and a few other guys in a circle with a white background. But I seriously hope that it's real! I can't seem to find out anything about it yet, but I'll be waiting to see what happens. Let's cross our fingers!
