Meh, this isn't great. The main character is a suicidal bullied outcast who is constantly being beaten up by random high schoolers, but also happens to be completely OP when it comes to fighting for some reason.
He can nearly endlessly parry a 100+ pound solid metal club swung by a monster that is at least 500 pounds of pure muscle, using a random metal pipe he found on the ground and a couple years worth of kendo experience he gained during elementary school.
He can slow down his perception of time when he gets in danger so attacks coming at him look like they're in slow motion, while he also moves nearly instantly.
He was able to catch other people's fists mid swing multiple times, while also dodging attacks effortlessly.
There is no system or level ups in this story, so he's doing all of this feats of super human effort completely naturally somehow.
This is just lazily written power fantasy/wish fulfillment that also dips into torture porn pretty often.
The main character has one of the dumbest "tragic" back stories I've seen in a while.
While he was a kid, he got in a fight with a relatives(?) kid over a girl and beat him up, so the other kid (with some magical vehicle knowledge) pulls an important part out of the MC's parent's car, which causes them to die in a car accident. Then the parents of the kid adopt the MC and treat him like complete garbage for some reason. They force him to do all the chores and beat him when his now adoptive brother sabotages him.
