this is an amazing manga. The story is 10 as it does its job: brutal revenge with gore, great. Art is amazing as the gore is good and Raul is so fucking sexy. Character is 10 as well as Raul is insanely amazing: he is so fucking hot, i love him so much. When he became sadistic, he was a perfect man, so, so sexy. Enjoyment is 10 as Gore is there and Raul is there. Overall is 10. Raul`s sadistic face is so hot. And i love how varied his methods of revenge and brutal it can be. damped quantum harmonic oscillators.
