The series has you at the edge of your seat awaiting the next gambit the protagonist will take. Very often at the edge of death and internally bound by a promise of persistent redemption fighting against their own internal demons, stray thoughts and feelings. Judging others as they do for themselves.
A great read... is what I'd live to say.
I would love to rate it 10/10 although the show has excessive fan service which is quite unfortunate as it sullies an otherwise fantastic piece of art. I can recommend this for someone who's at least 16+ and can overlook the sometimes indecent depictions.
