mondaichi tachi ga isakai kara smthng hagure yuusha no esthtica baka to test kore wa zombie desu ka PS: all the protagonist can do anything though somtimes the ways are not publicly acceptable
The Irregular at Magic High School...the most OP protagonist I've ever heard of (that can still be counted as human that is).
Sakamoto desu ga? This may be what you want I guess~ Edit: My bad~ Subete ga F ni Naru: The Perfect Insider Phi Brain: Kami no Puzzle
Kaichou wa Maid-sama. Both Misaki and Usui are perfect specimens of absolute perfection. Unfortunately, the anime never received its second season Ludwig Kakumei. The protagonist is just absolutely awesome. From the creator of Angel Sanctuary. Not sure if there is an anime. Death Note. Both the protagonist (Light) and the antagonist (L) are perfect. Tokyo Crazy Paradise. The protagonist (crossdressing girl, no, she's really a girl) is a legendary battle maiden of the yakuza, which she inherited from her mother. She's not a battle junkie, but she has crazy reflex and absolute beautiful when she does dress as a girl. There's just one problem, the translator for this manga sucked balls. Probably has an anime, but I've never watched it. If you've never read Hwang Mi Ri's manhwas, Hot Blooded Girl is a good place to start. Don't bother reading the rest of her stuff, she recycle her jokes. If you've seen one, you've seen them all. No anime, sorry. Anyway, anime sucks. Read manga.
Back butler Hayate no gotoku Tonari no seki-kun , his games are always cool haha and varied. One Outs , perfect pitcher , perfect gambler.
Female protag : Yamato Nadeshiko Sichi Henge. When she enters the scene, she is crazy awesome. Quite different with her regular self though. Skip Beat Again when she decided to do something, she did it in awesome manner. However, none of the above swag like Sakamoto though. Nothing compare to him. Male protag : Male high school studen is fooling around during class beautifully. Tonari No Seki-kun
