A very... curious take on the "yuri in highschool", and one that I am definitely here for. The series has a few notable problems (that I will get into shortly), but on the whole it is surprisingly wholesome for its morbidity, and quite charming in its romance. A very satisfying lesbian narrative.
Perhaps the most glaring issue is the framing of trauma = capacity to do violence, which is incredibly both harmful, and backwards. Given their line of work, the presence of abuse is very "understandable", but it cannot be the rationalization for their own violence. Awful, awful!
I am not well-versed into manga, so this might be my own inexperience showing, but I felt that the author used too few words to convey meaning and give context. Reading it, it felt sparse not exactly in plot or substance, but that very dutiful role the appropriate amount of words provides in letting you properly contextualize and follow along. It's not that I felt lost so much as I did not feel quite persuaded enough.
Lastly for the faults, the narrative became formulaic very, very quickly, and thus lost a part of its thrill. The protagonist pair duels a pair of opponents was established as the norm too directly, and that contributed to the already rather unrealistic plot being brought further into focus.
Apart from that, the series had a unique charm to it, and was a very satisfying read. And that is without mentioning just how much I adore women valiantly defending each other, it simply makes my heart melt. The extra-issued chapters were just the cherry on top, and compliment the grimness of the original with the perfect amount of jolly, gay fun.
