Hey I'm looking for some manga to read in my summer vacation:

Do not want: Shoujo, yaoi, yuri or something like that.

1st. I want to read another manga like Berserk, where a powerful (or skillfull at the least) dude (or many) with a sword (or other weapons) kills other people. Not necessary with much of a plot, but I would prefer not to have that many monsters. Have read Vagabond, Ares, and many of the same type, but I need more! Mature or seinen, whatever you give me!

2nd. I want a manga with some kind of tournament plot. Almost like Air Gear, not necessarily a team, but some kind of tournament. Preferably action, but not required. Would love some kind of gladiator setting. Have read some of Deadman wonderland, airgear, but need more here too!

3rd. Give me adventure! Epid adventure with medieval setting. Shounen or seinen.

Thank you!

You kill a man and you are a murderer, you kill many men and you are a hero, you kill them all and you are a god, or dangerously unstable.
