The Regressed Paladin Obtained the Archdemon's Traits

An era of ruin, engulfed by a phenomenon of "dungeonization" where places all across the world are turning into dungeons. The moment I faced death after defeating the Archdemon, I returned to the past, twenty years ago. As a countermeasure against the curses used by the Archdemon, my final enemy, I acquired traits related to curse resistance—but for some reason, I've become able to use the curses myself.
