Magic? Mana? Swords? System? Gods? Resurrection? Isekai? Time Travel? Dimension Hopping? Multiverse? Reincarnation? Tournament? What else?Everything has already happened and we are fighting against Chaos Himself and the Agents of Chaos as the final endgame battleSpoiler Alert! We all lost against Chaos Himself with only me left behind. Classic endgame clicheTurns out I was ultimately a {Keeper} despite me being different kinds of races and status. His goal was to kill me for a reason I wasn't able to understandHowever, before my ultimate death happened, there is one thing that has yet to happen despite everything that has already happened...『 ☆ Regression (Lv.MAX) ☆ 』An ability that suddenly appeared, causing me to instantly regress and go back in time to when I was seven years old, 13 years before everything started to happenThis is not time travel, an illusion, or one of my abilitiesEverything has been reset from scratch, but like other regression novels, my system, the 『 Omega System 』 has been preserved, but it's locked. A proxy system has been replaced to aid meSince it has come to this, I will make everything right and I will try to live for the sake of living!!! Then, I will search for answers of the meaning of {Keeper} and what it entails for meThe stability of the timeline doesn't matter... I will go all out!
