I'll be honest. The thing that makes this a Masterpiece is the Art that is this manga made back in 1992. If you seperate all the exploding heads and body's cleaved in half, it's not bad, but those things are drawn exceptionally well and they are just funny. The out of this world strength of the characters is insane and the main plot behind the protagonists strength is pretty damn simple. There is no over complicated plot, it's gore and action and lot's of blood and guts but done in a funny manner.

I recommend to shonun lovers. NOT SLICE OF LIFE. I REPEAT. NOT SLICE OF LIFE affiliated in any way. Shape. Or form.

This is a manga you could finish in a day and finish the day feeling "that was terrible" OR "that was so good I'm gonna add it to my favourites" which is what I did.
