No De I Cide thread? We fix this now. This is a unique fangame, made by someone called Izuriha, using lots of holy/demon imagery and gore. The music choice is interesting, it's a mixture of metal and seemingly trance tracks. The protagonist, Inahoozuki seems to be a demon child, according to her description.
I highly recommend giving this a try.

I was actually curious about this one. Maybe I'll give it a try today.
