Bleach

Narrator: Are you looking for a dark, edgy, and serious anime. Well than get the hell out of here, because Death Note: The Re-Bridged is not for you. This time, we got more suspense.
L: Should I add one sugar cube, or two…. oh, fuck it. I’ll use all of it
Narrator: We’ve got more action
Security Guard: Hey, a bus… The wheels on the bus go ‘round and ‘round-
(Bus crashes into a building)
Narrator: And we got a motherfucking AFRO
Aizawa: ……. I don’t even know how to respond to that?
Narrator: Watch as Light eats all your fucking potato chips! Don’t miss it, or you’re ass is going down in the Death Note. Watch Light eat your fucking mother

Narrator: Oh, shit. Wrong show… Uh… Here’s Matsuda
Matsuda: Hey, I’m Ma-
Narrator: FUCK OFF, MATSUDA! Death Note: The Re-Bridged! Watch it! Or don’t! Fuck you! Rated PG.

I was recently watching 'Rurouni Kenshin', and I came across 'Ruroumi Kenshin : Tsuiokuhen'. It is the story about Kenshin's life as an assassin, before he became a wanderer.

The show is very deep and well animated, using historical events and incorporating them with the fictional story. It is definitely a good, short anime.

Kenshin used to be a slave, untill his , masters were killed in a bandit raid. Kenshin was the only surviver, saved by a great swordsman, who would become his teacher.

Kenshin would grow up to become a skilled assassin, killing hundreds of people without regret or sorrow. He believed that he could save the world and make it pure again if he wiped all the evil from it.

(Im not going to spoil anything, so go ahead and watch it for yourself!)
