I'm searching for protagonist who seems naive/weak but
have strong killing intent or
he has potential to be a true assassin or
he is strong~~

or something like that...

for example nagisa in ansatsu kyoushita
he does not stand out that much but...
after 40 chapter or so..
his teacher acknowledge him as the true assassin...
even though he didn't look like one

plus,
other request...
I want a character who is very scary when he is pissed off
but most of the time..
he is funny or calm or difficult to be angry

example :
luffy from one piece
korosensei from ansatsu kyoushita

thanx in advance

First thing which came to my mind is Gun x Clover (fits kinda into first category. he doesnt seem weak/naive but pretends to be but its ecchi...)
well, I have some more (maybe)... but before I look into my list, any dislikes for genres?

well..

i don't prefer yaoi,yuri,gender bender

no shoujo-ish artwork
but if it is comedy...
then it is fine

well,
I prefer the element of supernatural,fantasy,action
but if there isn't...it's okay too~~

Ongoing!
The Breaker(completed) and its sequel(on-going). - (Seem both weak and naive, but has great potential)
Tower of God - Weak and naive, had great potential

Completed!
Holyland - Weak-looking, strong, really strong.
Kateikyoushi Hitman Reborn! - weak and naive! strong when someone precious is hurt!
Shingetsutan Tsukihime - weak-looking? Strong killer.
Tiji-kun! - Weak looking. Strong.

Something like these? 😕

This nagisa character sounds interesting. I sadly couldn't find the manga in question, do you perhaps have a link?

some are rather far-fetched but, well, you gotta see for yourself wether they suit your taste...
Id - seems weak but is strong category
Magi - Labyrinth of Magic - Luffy example category
Blood Lad - maybe (Luffy example category)
Mahouka Koukou no Rettousei - seems weak but is strong category
Nanatsu no Taizai - Luffy example category
Densetsu no Yuusha no Densetsu - usually lazy but if he loses control he pretty much kills everyone (but its due his hidden power)

He's talking about Assassination Classroom. Very awesome manga.

And I second Mahouka Koukou no Rettousei, preferably the light novel. The male lead is being underestimated, but in reality he's very strong (and scary when pissed off, which happens rarely).

woah~~
nice~ 🤣

most of it seems very promising~
I will check out all of them

i just read gun x clover
its nice and perfect but way too short~~ 🤨

maybe 50 or more chapter please~~
ongoing or not is fine either way 😀

Really??

That manga with that weird looking octopus teacher?

I believe I'm too prejudiced to give it a chance :-(

Yeah, I like Gun x Clover as well, even zhough Its short and last chapter omg... but, well its still ongoing so thats good XD

Well, some more....
Tora Kiss - A School Odyssey - last ranked and usually really lazy and funny but if it gets serious he's realy strong
Denpa Kyoushi - not strong but if he's pissed/challanged/whatever he does something awesome
The God of High School - another luffy type of thing...
Noblesse

Akame ga Kiru! Fits perfectly!

Seconding Noblesse.

Kill no More will probably fit. I personally only read the novel, and recently found out that it got adapted to manga. But from memory, it should fit pretty well. You might be able to find translated chapters online, IDK. The whole raw novel is up on Yu Wo's blog though, I believe. Think she posts all her novels up half a year after the serialization ends.

Honestly, that summary BU has up doesn't do it justice. It's about this assassin, who got sent into another world. He met another guy there, and their adventures start. There is proper plot, and the story eventually gets into Liola's past and identity, and the reason why he swore not to kill. So long as the art doesn't let down, the manhua shouldn't be as bad like the ratings say.

Ruler of the Land seems to be okay for this topic..
From everyone's point of view the MC is weak, stupid, and carefree. But he it turns out he is not only one of the most talented, but he is also the discipline of the strongest swordsman from the "dark sect."
It's a very funny, but also action- filled manhwa.
(It says it's gender bender, but it's really not..)
