Recommend Manga (Shounen & Seinen)

I recommend this webtoon.
The story is telling about people who are being bullied because
- they fat
- they poor
- they look weak
- they ugly
The main character is being bullied as he is fat, ugly and coward who can't do anything and blames everyone for his own unfortunate. He transfer school and had miracle happen where he can switch to a hot guy's body and his original body is sleeping. It's very slow progress to see how his character able to change from coward to be better person

Kang Hyuk live his life in disguise as his dead twin, Kang Hu, who had been killed by delinquents in his school. He planned to take down all delinquents in Hu's school and turned them to police as they all got away from Hu's murder.
Sooo good and badass. Hyuk is super awesome!
I really really sad that Hu is no longer live (Read Dokgo rewind). Such sweet bro. And sad that Kang's family are fell apart since the death of Hu.. Hope Hyuk will be happy again..

Setting on before Kang Hu death.
Hyuk is helping a little girl & her brother who had been bullied. Many schools involved in the school gang fight.
Background story for 2 other friends of Hyuk that appear on Dokgo, Jong IL & Tae Jin.

My favorite video game, Suikoden.

One shot story of Death Note
3 years after the death of Yagami Light
Finally Near said that what Light was doing wasn't all wrong.
I always find L as the reason why Light turned that way. He is the reason

Comedy slice of life story about friendship between a human and his demon king supernatural pet.
Satan is very cute pet.

Mysterious being that hosted in human body and eat human flesh just like in parasyte anime. But the monster origin is still unknown

Comedy. Ecchi. Humor Romance (not actually romance).
