Tsugumomo is easily one of the worst if not the worst manga to ever be created.
Story:
The story is generic and let´s not fool ourselves no one reads it for the "plot" , everyone who reads tsugumomo understands that people just are there to see literal hentai with censorship.If it was a normal shounen with ecchi it would be probably much better.
Art:
It´s decent and the fights are actually well drawn.
Characters:
There isn´t a good character in this manga everyone is just an object for the sexual moments to happen, only the mc and Kiriha have a semblance of motivations.
Enjoyment:
it´s amazing how atrocious eveything is about Tsugumomo , to the point that the only way to enjoy it is by turning the pages of the manga with only the left hand.
