If it wasn't supposed to be grounded in realism, it would've been a cool line.
Still, a nice meme: https://i.postimg.cc/gJz7XTdj/i.jpg

Had MC been a bit more ruthless like his friend, this would've been a lot more enjoyable. 
Don't get me wrong, kids: violence is never cool... but some f*ckers need to have Biblical vengeance enacted upon them.

The old cliché: MC gets beaten to a point that would've killed 10 men all because he won't let someone else be harmed... and then, when he hears his friends saved them, he gets up and batters unbelievable numbers + the OP main villain.

This has been pretty lame but at least it was a fast read.

I'm a black belt in judo, I just watched you beat the crap out of, like, 20 guys in a few seconds, K.O. most of them, not even pant for the lack of effort... but, yeah, I can take you on.
Delusional or bad writing? 

Is this like, Yuck, furry?

Sigh. Obviously fakery to flush out whoever leaked info to Hu in the past. With that in mind, shouldn't the sound effect in the last panel have been translated? 

https://i.postimg.cc/Kj1VBYps/i.jpgOkay, now tell me this piece of sh*t doesn't need to have his skull stomped on until he's retarded...
This is what bothers me about these kinds of comics: the authors make the villains pure evil, but then think a little slapping is the justice readers want!

No, a petty dislocation is a simple pop back in and two weeks' rest. Is that really all this piece of sh*t deserves?

Why does he have to smack down these fools in order? Why didn't he just jump the ringleader outside of school as soon as he knew who it was, deliver the deserved maiming and extract the names of the other culprits via torture?
This plot is weak and the revenge is borderline gay. Sh*t, I thought this bad-arse, OP MC would be breaking bones at a minimum, instead, we get rainbow flags.

Faggots acting tough because they expect a 5 v. 1 beatdown.

The same faggots pretending they're losing: https://i.postimg.cc/BvvWSpPZ/i.jpg

Dweeb: he carries a weapon around.MC: cool, I'll just let him take it out during his beatdown... because: like, why not?

Faggots with knives...

Nah, man, this MC's a f*cking tranny! He should be murdering this bastard, not slapping him for chuckles.

Dude, he kicked your brother so much, he coughed up blood... and he's bragging about it.That means he gave your brother fatal internal injuries, and that sh*t amuses him!
MC had best cripple this motherf*cker or this comic is gay.

The dude was going to break your legs. Remember that when you hurt him.

Break his arms! The f*cker knew about it raining during the park beating, so he was probably there, and anyone pulling a knife deserves to get f*cked up.

He's an arse hole but at least he has a brain. That's actually a dangerous combination  - just look at politicians!

About time one of them gets some good punishment. 
This fag will have a bleeding arse hole in juvie.

Nah, man, he's not f*cking these rats up even 1/4 of what they deserve! Break some bones, make them eat sh*t or something... save the throwing off of rooftops for the bosses.
