Leave the Party, Then Make a Pact with the Saint

[Western fantasy dungeon +++ flaw-reversal golden finger +++ a cast of beautiful girls with unexpected sides +++ a hugely satisfying story] Ron transmigrates into the lowly tactical commander of a dungeon adventuring party. From the start, the "Golden Dawn" squad, adored by the whole city, kicks him out in front of everyone because he has no combat ability, leaving him saddled with a colossal breach-of-contract debt of 100,000 gold coins! At the end of his rope, he awakens his one and only divine skill, [Tactical Trait Reconstruction]. As long as he resonates with a contracted girl, he can turn her "fatal flaw" into a "god-tier buff"! And so, the seven "problem girls," dismissed as good-for-nothings and shunned by the major guilds, become Ron's trump cards for sweeping through the abyss.
