Fukushuu no Taishi - Level 9999 no Bakumatsu Isekai Tensei

[MangaDex]

 

[NLight]

Imagination must really be struggling when 99 levels is not enough to make a compelling strong main character.

 

[sedition]

Complete dog shit unfortunately, the main character's feeble personality and the story's refusal to allow him to grow at all makes this feel terrible to read.

Spoiler: story content

At one point he spends thousands of years training after watching all of his friends and the girl he likes die, then comes back and kills all the monsters that did the killing, but then reverts back to his former cowardly self despite the 100 level jump and thousand year time skip spent training.

It just genuinely makes no sense for the story to have that character growth segment then completely ignore it not even 2 chapters later.
