The MC is level 1 and has never been able to level up despite years of training and monster killing, which makes everyone think he is already at his limit cap
Yep, totally sucks

His old family dumped him because he was too weak to survive on their OP island that fends off the monsters, his ex-fiance advised him to give up on fighting and live as a regular person as not to get himself killed, and he just wants to be recognized by those people

Then there is another group who tried to kill him, then denied responsibility, then got away with it because of their status, those he wants to kill or humiliate as much as possible

This is the line he draws, for those who humiliated him or were mean to him he just is a d*ck in return but for those who tried to kill him he wants to kill

Pros:

• • The revenge plot. Most of the modern revenge novels don't think too deeply about the reason for revenge, any betrail that came out of the blue seems to work. MC is blind until it's too late, then, he instantly evolves into Chad revenger like by magic. But this novel isn't like that. MC, like everyone else, understands the reason why is he mistreated. Subjectively there is no real betrail here; it is more like an inevitable process. What caused him to harbor resentment is a series of incidents born from MC's obstinacy and weakness.

• • Believable morals. There are no inherently evil characters (so far) in this novel. Unlike the usual for JP novels black and white logic, this story's characters tend to be grey. You will like it if you vomit from revenge stories where betrayers are cartoonishly wicked.

• • Characters growth. It's not neck-breaking but the amount of growth covers what is minimally required to prevent the novel from walking in circles.

• • Minimum cliche. If the popular tropes are unavoidable then the author is trying to use them organically. It is by no means a generic story mindlessly built from overused tropes.

Cons:

• • The author tends to abuse breaking the timeline. Sometimes he does it amidst the action to show you an ill-timed exposition of events prior. When narration returns back to chronological order, you lose any hype you had about the battle or difficult situation. At other times he can make a time-skip forward when you do not expect it at all.

• • Jumbled world setting. It's a mashup of all cultures known to the author. Samurais, knights, westerners, dragons, elves, demons, eastern names, western names, it's pretty bad. Not horrible though. To be honest, I handle it with a little extension that changes for me every Japanese/chunibyo term with its Chinese/Western analog. It works like a charm. Call me a pervert if you want.

• • There are no detailed s*x scenes. The author does not even talk about them, s*x is only implied. It's a wonder how the "Mature" got in the genres list. But mind you, at least MC is not a typical beta protagonist, he doesn't scream when his virginity is in danger. Maybe s*x scenes were left for the LN version (absolutely hate this) ? I wish I could compare them.

• • Overlooked revenge events. The culmination of the first episode of revenge was largely glossed over by the author, mainly because it has a lewd nature. As I mentioned before, the author only implies lewd things, never shows. Imagine that after MC captured his target, you turn the page just to see a "month later" line and the next line tells you that the wrongdoer became a member of MC's harem. Nothing beside. How you can mess up the most crucial part by completely skipping it?
