The Reincarnation Crisis

"No overpowered skill, no fancy level-ups, no broken cheats, and on top of all that, I have to kill those who do."
"Go my child, the reincarnates are wreaking havoc in their worlds, and I need you to bring their soul back to me."
This is an isekai fiction unlike the others. With no over-powered abilities, the protagonist needs to use his own strength, wisdom and resourcefulness to help those in crisis and hunt down the reincarnated ones. Can the protagonist complete the impossible?
