Then you don't need Good Luck
You need the ability to overcome Bad Luck

Happines and Light needs a source to exist
Hatred fuels itself and Darkness exist where there is no Light

Thanks for these recommendations! I have already read Mx0 and Iris Zero and Kurogane (IKEZAWA Haruto) are among my favorites, but the others look very promising.

"Always go too far, because that's where you'll find the truth." - Albert Camus

Definitely The Legendary Moonlight Sculptor (Novel)! He flatters people to gain their favor and helps people to gain their loyalty. He'll trick anyone if he gets something out of it, though he does still have some morals. The series is very long.

The Legend of Sun Knight / The Legend of Sun Knight (Novel) - He's the leader of the renowned twelve holy knights, yet he best handles issues "behind the scenes", secretly organizing things so they all fall into place for him later.

How about Houshin Engi? It's a long and completed shounen series with an extremely crafty lead. He always plan ahead, and even if his plans fail, he usually have a plan B or plan C. He is also not afraid to use dirty tricks, so much that sometimes his comrades are ashamed to be on his side.

I know how you feel, just watching how reckless the "do gooders" are makes me skip the scene or cover my eyes lmfao...heres some I think are "decent"...

Ao No Exorcist (amazing manga & anime)

Hope they're to your liking Peace... 🤢

i like the red paint that comes out when i stab you...

Ao No Exorcist is definitely one of my favorites. I don't really want novels, because I would still like to read manga.

Also, it would be really cool if the protagonist has multiple faces/personalities.

I double recommend The Legend of Sun Knight then; manhua, and in addition to the crafty protagonist, pretty much all of the characters have multiple personalities.

Ageha wo Ou Monotachi - a bit more seinen styled than shounen, and it's just a light comedy, but you may like it.

+1 to this. 🙂

AIKI dude is anything but dumb, tho u wouldn't know it from first impressions >>
Random surprise one the breaker: new waves this is surprising as the first one is the total opposite, kid was a fricken moron bursting with power. But now due to reason I won't mention he has way less power and its unstable, so to fight stronger people he has to be craftier during the fights... he's still a bit stupid tho >>

Few favs
Comedy:
Kyou kara ore wa!!, Mx0, Angel Densetsu, Skip Beat, Ai Kora, The Devil King is Bored

Romance:
Hana to Akuma, No bra, Shinigami Trilogy, kindan no koi de ikou, Usagi Drop, Threads of Time, Girl Friends

Most under rated:
Kindan no koi de ikou, kyou kara ore wa!.
m0r l83r... maybe >_>

Konjiki no Gash!! might fit 😕

Definitely The Legendary Moonlight Sculptor (Novel)! He flatters people to gain their favor and helps people to gain their loyalty. He'll trick anyone if he gets something out of it, though he does still have some morals. The series is very long.

The Legend of Sun Knight / The Legend of Sun Knight (Novel) - He's the leader of the renowned twelve holy knights, yet he best handles issues "behind the scenes", secretly organizing things so they all fall into place for him later.

I second (..or third?) these two series!!! They are absolutely great and I could just reread them over and over XD
but I would recomment The Legend of Sun Knight (Novel), since it's a lot better than the manga (IMO)

Gamble Fish - Very crafty male lead.

Gamble Fish looks like a nice read, and I've already read Konjiki no Gash!!.
Mangas like Hunter x Hunter could also work, since Killua is pretty crafty.
