Reincarnation Instance? This Is All Part of My Script

The heavens descended, dungeons invaded, and all who reached the age of eighteen entered the cycle of reincarnation. As humanity struggled to survive in fear, I discovered that these so-called death dungeons were actually worlds from works I knew intimately from my past lives. Even more remarkably, I awakened a multiverse character template system. In *Bleach*, I stood on the throne of heaven, the Ea sword pointing at Aizen; in *One Piece*, the Zanpakuto reduced Im to ashes. Until all the dungeons were cleared, the barriers of reality shattered, and Thanos and his army reigned supreme over Earth. Facing this cosmic overlord who even the Avengers struggled with, I smiled and blocked his path.
