Overview

Light was the only human in a party otherwise made up of the setting's other tribes, and when his so-called comrades decide he's expendable, they leave him for dead in the depths of a dungeon called the Abyss. What they didn't count on was the Infinite Gacha: a power that lets Light summon Level 9999 allies to his side. Three years later, he's built his own underground kingdom out of loyal, absurdly overpowered followers, and Backstabbed in a Backwater Dungeon spends its volumes walking him back to the surface to make his former party pay.

What it does well

The gacha hook gives the harem-building at least a mechanical reason to exist. Every new ally Light gains is tied to an actual pull from his power, not just another attractive character wandering into frame, and the manga leans into that structure enough that the harem feels like part of the premise rather than an excuse bolted onto it.

The revenge plot itself stays legible. The manga knows exactly who betrayed Light and why, and it paces his return and his targets one at a time instead of losing the thread in filler. If you're here for the wronged-hero-returns-to-settle-a-specific-list structure, the story delivers that cleanly.

It also does exactly what it says on the cover. Big power gaps, absolute loyalty from Light's followers, a clear villain to take down in each arc — genre fans looking for that specific shape of story get it without the manga pretending to be something more restrained.

Where it falls short

The pace is the biggest issue. New allies, power-ups, and plot beats show up quickly enough that they rarely feel earned — the manga tends to tell you a character is now devoted to Light rather than build to it, and the effect is a story that moves through its own hooks faster than it develops them.

The harem angle also crowds the revenge plot more than it should. New allies keep entering the story, and the fan-service attention paid to introducing each one starts to compete with, rather than support, the comeuppance arc that's supposed to be the actual draw.

Beyond genre execution, there isn't much here that pushes past convention. If you've read a handful of betrayed-hero, overpowered-revenge stories already, very little in the setup, cast, or structure will surprise you.

Verdict

This is a manga that knows exactly what audience it's for and doesn't apologize for it: harem-heavy, power-fantasy revenge with a gimmick to justify the harem part. It moves fast enough that character work gets shortchanged, and it won't win over anyone tired of the genre's tropes, but if the premise sounds appealing rather than exhausting, it delivers precisely what it promises.
