Well, premise is nice and I like good Koikatsu CG's, but for now there are almost no content, so I can't properly judge.
Airi is cute and adorable, and it will be nice to see how corruption will go. If I understood description, then it should be NTS to NTR and it's rare and interesting scenario (but I hope MC will not be pathetic cuck from the start - it's always a huge turn off for me).
