Shadows of Eternity: The Dual Reign

Shinichi never expected to be reincarnated, let alone with memories of two vastly different past lives: one as an all-powerful demon lord who ruled with fear, and the other as a noble holy knight revered for his heroism. Struggling to reconcile his dual identities, Shinichi awakens in a world where magic defines everything-and his power is unlike anything the modern age has ever seen.

After shattering the academy's magic crystals, which couldn't even begin to measure his strength, Shinichi's overwhelming abilities attract the attention of the Arcane Academy's headmaster. Seeing his potential, the academy ropes Shinichi into an unusual role: balancing his student life with teaching as a part-time professor, tasked with guiding the next generation of mages.

But life isn't so simple. Two girls, Elena, a fiery mage, and Ayane, a kind healer, recognize Shinichi as the man they loved in their past lives. Their romantic antics, along with a growing group of rivals and admirers, turn his days into a comedic whirlwind. Meanwhile, memories of betrayal by his closest friend, Tatsu, resurface as a shadowy organization begins to move, threatening not only Shinichi but the entire world.

Caught between the duties of a professor, the chaos of his growing harem, and the mysteries of his past, Shinichi must use his unparalleled powers-and his unique ability to master any skill by observation-to protect his new life and uncover the truth.

"Shadows of Eternity: The Dual Reign" is an anime-inspired tale of thrilling battles, hilarious romantic misadventures, and the challenge of balancing overwhelming strength with an unexpected teaching career.
