DxD - Multiverse: Daily Life Of The Sephiroth Hero - Chapter 45

He died. Not by fate, not by accident, but as collateral in a hunt between beings beyond mortal comprehension.And yet… death was only the beginning.Chosen by a mysterious entity known only as Echo, a sarcastic soul from Earth is offered a chance at a second life. Gifted with ten draws from a divine treasury, he obtains powerful treasures, a rare bloodline, and a mysterious system known as the Limitless System.But what begins as a straightforward reincarnation takes a twisted turn when two dragon inheritances—Thunder and Fire—collide within him.Reborn not as a man, nor as a beast, but as an unknown species—a fusion of human and two True Dragon Inheritences—he awakens in a scorched battlefield beside a dragon egg, unaware that his birth was witnessed by fate itself.After surviving the near-fatal clash of legacies within him, he emerges anew… no longer Zaroth, but Primus Xal’Zaryon Drakonis, a name that shakes the very fabric of mana around him.With his soul, body, and bloodline perfectly harmonized between human and dragon, Primus sets out into an unfamiliar world ruled by ancient clans, dangerous beasts, and kingdoms teetering on the edge of Eternal War.But power always draws attention—and with the secrets of his origin, the Limitless System at his side, and a destiny marked by a Primordial-level Mark of Fate, enemies will rise from shadows unknown.
