A full-on mind break, training game from Frrill.
The MC is infatuated with the main heroine but he and his off the grid organization won't stop just at that.
While the art is great and the situations are not always on the darker side of things, the protagonists does not do it for me. The whole "revenge" story is just an excuse for him to plot everything.
I you can stand the MC motives, you will find a game with an interesting and developed story and really good CG.
