On one hand: better gameplay than the first game, an excuse plot so unapologetically stupid that it's hilarious, some great new additions to the cast, no Momo.
On the other hand: worse art style (imo), some weird pairings/dynamics, some not so great additions to the cast, you cannot bang Kyu.
On both hands: Porn. Lots of it. Pretty good too.

I bought this game on release day. I regret nothing.

Score: 8
