Saitama Chainsaw Shoujo is about a girl who got bumped by her boyfriend and then decides to commit a massacre in her school in order to kill him. And she will use a chainsaw to do so.
It’s pretty much like Columbine but with a chainsaw.

What bothered me with the story is that, Saitama didn’t have a real strong reason to commit such massacre.
Of course she’s shy and doesn’t have a lot of friends. But still I don’t think that justified such massacre and I was expecting some revelations about an obscure past or something like this.

This said, others characters attitude were really… strange.
I mean nobody’s scared when they saw a girl covered with blood and with a chainsaw. And all they do is to complain about how dirty her shoes are or fighting her like if they were zombies.
They’re really not taking things seriously and it’s really not like they’re scared of being killed.
It’s completely unrealistic but is it bad? It really gives a funny, horrifying and quite demented atmosphere which is what I expected from a manga like this.

The students really represent an obstacle for her and her determination is challenged.
Also her relation with her best friend is really well developed and challenged as well.

The art is really nice, there’s some blood and gore but not excessively.
The fights are really well done and quite entertaining.

Overall it was really a nice manga if you like this kind of horror story with people turning all psychotic.
I’m just a little bit disappointed because we didn’t have a lot of revelation about Saitama but it still good anyway.
