@Ribath I mean the format. It's identical to pilots to show the reader sample of a story, introduce the premise, the setting and the characters. I guess it really worked well if you desided alredy if you want to read it or not.
Also, is it really delinquent manga? I guess there are gangs and stuff, but for me it was always about atmosphere rather then brawls. This one is more of a quirky school fighting manga - you know, with quirks being ancient martial art descent, ninja clans or beating enemies with a ruler, or fighter girl fiancee - that kinda stuff. With quirk being detective leaning. And I am personally curious if author pulls off enough plots to sustain it, because using brute force to solve complicated stuff is pretty rare concept for detective stories.
