@lolmaolol It's a similar situation to One Punch Man, and to a lesser extent Mob Psycho. The MC is essentially all-powerful for the sake of the story, so their conflict is limited to often petty reasons such as being annoying or a misunderstanding. That being said, One Punch Man benefits from the side characters as their arcs drive the bulk of the action itself while Saitama handles the comedic aspects.
Here they seem to take a similar approach. Our MC can seemingly handle anything with his fists similar to Saitama (actually, looks like Mob but has the powers of Saitama). Side characters have been introduced to add conflict that would otherwise be solved immediately by the MC. Yet the problem here is how more side characters are introduced without proper investment, and overall overshadowing the plot set by the MC.
The plot is just him needing to survive and pass enough classes to reach the very top. The situation in this chapter is basically a fight with the school bully.
