Hidden badass, obfuscating stupidity, etc. Doesn't necessarily need to be a pacifist. By modern, 2005+ or something.

TY.

You should try this one:
[Daisaiyuuki Bokuhi Seiden - The Story of a Very Handsome Man](https://www.mangaupdates.com/series.html?id=115559)
If you get over the drawing-style its awesome, the jokes, the guy itself (somewhat between too awesome and too stupid) ...
I have to note, that the start isn´t that good, i gets a lot better when the girl is with him 😉

Do you have a special genre like history or stuff? Or should the be simply cool/strong/stupid/somewhat loveable?

I thought this Manhwa was hilarious too:
[Transfer Student Storm Bringer](https://www.mangaupdates.com/series.html?id=63461)

I read a lot similar to the one below - (i suscribed, if this one is good i could post a lot more)
