Kenshyuk

Oh hell yes. Berserk is an awesome, awesome seinen manga, possibly the best one yet, that revolves around the life of a struggler named Guts, a man with an iron hand and a gigantic, iron-slab-like sword known as the Dragon Slayer, who fights and struggles to kill the one who used to be his very best friend, but made a sacrifice to the wicked members of the Godhand to resurrect his mangled body and rise in power, killing all of Guts' comrades and violently *ahem* violating his lover. Having sworn revenge and obtaining the Dragon Slayer, Guts travels aimlessly around the land, killing several transforming deadly demons known as apostles along the way, and eventually almost makes his way to Griffith, the very person he's aiming to kill. There's a hell of a lot of stuff(and GREAT stuff) that happens along the way, but enough spoilers. Read it for yourself and find out.
