Oh gosh it´s another story of a deranged high-schooler manipulating others into manipulating others into killing somebody via psycho games that make no sense
Onee san who keeps a high school boy is trying to a quick, simple gag series, and it succeeds. Aim low, hit low, forgivable. It does not pretend to be something it is not. It did not start off as a high drama and then become a gag series, just consistent all the way through.
1-nen A-gumi no Monster is trying to be a psychological drama/horror, but instead it's become a convoluted soap opera mess. Aim high, hit low. It had a promising start, but it became clear that the author had no real plan for the series, and it's consistently gotten further and further from the mark until it is unforgivable.
The fact that this author can make a manga that pisses me off to the point of no return and then make this manga which I eagerly wait for a new chapter everytime is amazing.
GTO except everyone is a horrible person and its written like the author wants to be M. night Shyamalan on meth. This combines into a hilarious trainwreck.
