I've been itching to write this for a long time by now.

Story 10/10
Zankoku na Kami ga Shihai Suru is a catching story about a high school boy trying to cope with his stepfather regularly abusing him. He's suffering, running away, crying and losing it, then he faces it and solves his problem only to find another one. He is constantly giving up and trying to vanish, then being forced to live and try again.
It's not 'BL' as such, but certainly a piece full of love, desire, overlooking, suffering and regret.

Art 8/10
This manga started in 1993. That is a year before I was even born, so of course the art is not as fancy as in some newer ones. If you give this up because of it, I pity you. It's not bad at all once you get used to it.

Characters 10/10
The characters are beautifully pictured with real personalities, combining both good and bad traits. Sometimes the characters are lost and looking for help, sometimes they fight and face the reality. Everyone is unique and I have the feeling that even those of peripheral importance are strong individuals.

Enjoyment 10/10
I laughed, I cried, I was completely drawn in the story. I wasn't feeling bored even once. This manga is just brilliant.

Overall 10/10
To sum it up, I love this manga. I found it when I was looking for something psychological - and it may actually be the best manga I've ever read. It's a masterpiece.
However, I would recommend it only to those who are able to understand the meaning of being wounded and can accept that sometimes, wounded people do stupid nonsense when trying to forget the pain.
