Hi, I'm looking for a good action anime. I want it to have a serious plotline and am looking for something where there is a social structure involving rankings in status that distinguish one from another. It can be something like Sword Art Online where Kirito is a high level thus being impressive to most people, or in Chrome Shelled Regios where Layfon was a heaven's blade wielder, or Beelzebub where Oga is just overpowered.
I've seen

Attack on Titan
Zetman
Beelzebub
Legend of Legendary Heroes
Mirai Nikki
Deathnote
Zettai Karen Children the unlimited
Berserk
Campione
Valrave the Liberator
Hagure Yuusha no Estetica
Guilty Crown
High school of the Dead
Mondaiji-tachi gaa iseka
Zetzuen no Tempest
Hataraku Mao Sama
FMA Brotherhood
Ao no Exorcist
Dragon Crisis
Ichiban ushiro no daimyo
Naruto
Bleach
Fairy Tail
Blood Lad

Magi
Infinite Stratos
Darker Than Black
Arata Kangatari
Susei no Gargantia
Btoom
AND A LOT MORE

So I don't mind if there's ecchi or if it's bloody, rather I prefer bloody, but I want awesome action scenes, ones where you're for sure impressed, and the main character should be strong and impress everyone, something like a secret power would be cool too that the main characters friends see at some point
Nothing like one piece where there are like Bear's amongst the humans as if they were humans too or like a walrus man or stupid things like that, I need something seriously authentic and human,
thank you!
