After binging it, my head hurts from trying to grasp this convoluted mess.
Guren 's side story is nice but that's it really. I actually feel sorry for Yuu seeing he is an actual victim of brain damages.
This is so stupid I am actually in disbelief the author & editor had the galls to write/approve that in a shounen(?) magazine lol.
Gotta give credit in how much he is willing to experiment but I still feel iffy with the pacing/character development of the story.
