It depends. Some successful manga artists can earn a lot of money through book sales, merchandise, and adaptations. But it also requires consistent hard work and having a hit series. Not all successful artists become extremely wealthy.
The unique storyline and well-developed characters make it stand out. The contrast between the devil's supernatural powers and the urban setting creates an exciting plot.
There were many anime works that had such male leads:
Naruto Uzumaki in Naruto: He has a strong ninja strength and a strong family background, so he has a lot of power and wealth.
2 Monchi D. Luffy in One Piece: Although he was an ordinary teenager at first, he gradually became strong and possessed a lot of wealth and power through constant adventure and hard work.
3. Ishida Yulong in " Death ": He was a very rich and powerful figure and a powerful swordsman. His appearance was also very handsome.
4. Nozaki Ichigo in Silver Soul: Although he is an ordinary person, he has strong combat ability and a lot of wealth and power.
5. Alan Yaeger in Attack of the Giants: He had great strength and strategic ability, but he also had a lot of wealth and power. He was a very handsome character.
I recommend the following two novels to you:
1. "Pastoral Trifles: A Poor Girl Turns Over": The female protagonist transmigrated into a little girl in a remote mountain village. Her family was poor but had a kind mother, a passionate brother, and a gentle sister. Later, the female protagonist decided to make a fortune by making money with three hands and change the living conditions of the family.
2. "The Farming Story of a Farming Lady": After the female protagonist transmigrated, she survived during the war and began to become rich. She farmed and did business. She was filial to her family and kind-hearted relatives. Both books are novels about transmigration, business, and farming. They match the plot you described.
