Hey! First post, and wanted to find manga with a really specific premise. I've always liked stories involving an ultra powerful character who looses their powers, and have to start from square one. The character can be male or female, and while they don't have to be the lead, it be preferred.

Aiki - Kunitoshi Joukyuu is a lazy ass, good for nothing pervert. Who also happens to be a supposed genius master of Aikido, the strongest in the world, if not because his father sealed away most of his abilities before dying.

Can't think of any other as of right now. So I'll get back to you if I remember.

Technically, this is your second post.

Kurohime for one

Oh geez, yeah, I accidentally hit the "create topic button" twice, so that's my bad. And thank you both! I'll look them up.

Happens in The Breaker: New Waves, sequel to The Breaker.

Nanatsu no Taizai Various characters, MC included have their powers greatly diminished because they lost their weapons.

Change Guy Happens to one of the MCs because of a body switch, he shows up again much later in the story though.

Hataraku Maou-sama! MC loses most of his powers when transported to another world.

Hunter x Hunter Happens to the MC but it's very late in the story (current chapters actually)


If you don't mind animes : Darker than Black: Ryuusei no Gemini Happens to male lead in this sequel to Darker than Black
