The concept of a hero who can defeat any enemy with one punch is very unique. It subverts the traditional idea of long, drawn - out battles in superhero stories.
Tatsumaki, also known as Tornado of Terror, is a powerful esper in the novel. She has psychic powers and a rather arrogant personality. She often gets involved in various battles against powerful monsters, and her relationship with other heroes, especially Saitama, is quite interesting as she initially looks down on him.
It depends on his personal interests and lifestyle. If he has a lot of free time and enjoys reading, then it is likely to be common for him. However, if he is very busy with work or other activities, it might not be so common. Also, his access to the internet and devices plays a role. If he has easy access to a smartphone or computer, he is more likely to read online novels.
I'd suggest looking on platforms like Webtoon or Comixology. Sometimes they have a wide range of manga, including the one you're looking for. But make sure to check for legal and authorized sources to support the creators.
It could influence his creativity. The diverse plots in online novels might inspire his own creative thinking. For example, if he reads a science - fiction novel, he might get ideas for his own stories or projects. Also, it might affect his time management. If he gets too addicted, he could end up spending a lot of time reading instead of doing other important things like studying or working.
Well, you could check out platforms like MangaDex or Lezhin Comics. Sometimes they have a wide range of manhwas, including 'A Man of Virtue'. But make sure to use legal and authorized sources for a better reading experience.
