Saitama in One Punch Superman was a very powerful hero, but the reason he couldn't become an S-class hero was because of some problems with his personality and motivation.
Saitama was a very self-centered person. She had a very strong pursuit of her own strength, even at the expense of the interests of others. This kind of self-seeking performance often made him do some selfish actions, such as attacking other heroes or ignoring the safety of others in order to protect himself.
Saitama's personality also caused him to be unclear about some moral values. He did not care about the feelings of the other heroes. He only cared about whether he could become stronger. This kind of attitude often caused problems in teamwork because he did not understand the importance of teamwork.
In summary, Saitama's personality and motives were the main reasons why he could not become an S-class hero.
Sometimes, it's about having a strong sense of purpose or a unique ideology. This can drive the ordinary class to constantly strive for improvement. They might be motivated by a desire to protect their loved ones, their home, or to prove something to the world. Their unwavering determination can gradually transform them into the strongest in the light novel world.
Manga Saitama's progress speed is hard to define precisely. It can be rapid in intense moments but might slow down to flesh out details and relationships in different parts of the story.
Another plot could involve Saitama using his new S - Class status to reform the hero system. He might see all the flaws in it, like how some heroes are more concerned with fame than actually saving people. So, he starts making changes from the inside. He could introduce new training methods or even a new ranking system that focuses more on a hero's selfless deeds rather than just their power level.
To become a member of Class Comics, first, keep an eye on their official channels. They might announce membership drives or provide instructions on how to apply. Also, it could involve filling out forms, providing certain personal information, and maybe even meeting some criteria related to your interest or participation in their activities.
Genos would probably be even more in awe of Saitama. He already idolizes him, but with Saitama being S - Class, Genos might see him as even more untouchable. He could become more protective of Saitama's new status, trying to fend off any detractors or those who might try to take advantage of Saitama.
