Incredibly shallow and simplistic. If there is any plot to this manga then I couldn't find it. MC gets bullied and then makes friends... that's it. I consider this slice-of-life since there doesn't appear to be any story arc or purpose to anything. Really nothing stands out about this manga at all, and I assume most people will find it incredibly boring. There is zero hook here. MC learns new things from his friends, and that's as deep as the manga gets. Artwork is generic and low quality. Action scenes are just simple sword flashes without any detail at all. None of the characters makeany sense. Everyone is either a psychotic murderer or an angel, which is an indicator of bad writing. Definitely skip this manga.
