the name of the topic is a bit unique but thats what I'm looking for.. a manga where the protagonist has some kind of "power" or "knowledge".. or however you want to understand the word... that gives him some advantage.

can be any genre except yuri and (ecchi+harem+romance)

Must it be only the protagonist has it or is it okay for it to be a rare advantage that only a select few has?

may be Zennou no Noa - The World of Lostmemories but you don't gonna like the end...

Not sure if this is what you meant but the only ones i could think of is , Code Geass and Death note. Light has the notebook wich many ppl doesnt have and Lelouch has his geass wich gives them an edge, Prefer the anime on both though...

it can also be a selected few and I allready read/watched everything you reconmented 😀
...is there something else out there?...well maybe sword art online (novel) and The Legendary Moonlight Sculptor (Novel)

kurogane (ikezawa haruto)?

I am vindicated!
I am selfish;
I am wrong!
I am right,
I swear I'm right.
Swear I knew it all along
And I am flawed!
But I am cleaning up so well
I am seeing in me now
The things you swore
You saw yourself...
