If only doujin artists knew in 2003 that guys would be way more interested in beautiful feminine boys than females. Especially in compromising situations.
I really wish someone would do Mobage Cards for this series, I mean there are far more then enough girls in it (plus Rando-Yuna).
I feel it would be a fitting tribute for this cast. Not to mention it would likely have the same feel to it as the Highschool DxD Mobage, especially when you consider they also have a trap/crossdressing character as well.
Also, it would be interesting to see a hentai doujin between Randou-Yuna and either those three guys or the one Teacher that tries to get Yuna expelled.
Either way, this series needs more love on E-Hentai.
