I bet this is terrible to read if you have watched Gintama,,, I haven't (still) though
A clear 5/5, 2019 and 2021 me agree on this.
It's super fucked up and I don't recommend you to read if you enjoy Gintama. This is just... hot. Until now, I haven't found anything similar to this anywhere so it's also,, unique. The guy on the cover gets stuck in a wall and one of the other main protagonists rapes him before leaving and forgetting him there, then a group of men arrive and gang rape him. That's basically the summary.
