無能は不要と言われ『時計使い』の僕は職人ギルドから追い出されるも、ダンジョンの深部で真の力に覚醒する (As a Watchmaker, I was Kicked Out of the Craftsman's Guild Because My Incompetence was Deemed Unnecessary, but I Awakened to My True Power in the Depths of the Dungeon)

Apologies if it's been recommended before but I tried searching for it without much luck.
Synopsis: Standard revenge concept - MC gets framed for things he didn't do and is sent off to a prison of sorts. He nearly dies, activates his proper OP powers and joins up with some girls to get his revenge on those that wronged him.
The interesting bit about this for me is the actual origin of his powers as his skill was misinterpreted by the religious organization responsible for naming skills due to the ancient language not being accurately translated.
2 LN volumes and 4 manga volumes so far.
