Nice way to kill time if you like the sci fi/martial arts mashup.
Nothing exceptional or deep about the story.

Honestly it was good until it stopped making sense. He would go into the outside world & defeat high ranking people (3 star villains or whatever) but get back to school & have trouble defeating a 2 star. I didn’t get that. He killed 2 assassins while being a 1 star & they were 2 lvls above him at the time (3). Not to mention 3 star mutated zombies but had trouble with a guy on the same lvl as him. Both 2 stars. Almost as if they forgot they led us to believe he was as strong as a 2 star already despite not being ranked. Honestly it should’ve been a piece of cake to defeat someone on his lvl but he had more trouble with a 2 star. Then he did with a 3. Which is wild.

This started out great, but after a while it just blends into average. I agree with what user "logan3" said. But it has some humorous nuggets.. Sadly i cant rate it higher than this

MC receives a neverending stream of fortuitous encounters. Everyone is an ass to everyone else. MC rescues a high-class girl who falls in love with him. Everyone is irrationally out to start drama and kill others. MC wears a constant expression of arrogance. Etc.

Your standard, generic martial arts fantasy: good for wasting an evening.
