Yahiko Kusanagi, a 20-year-old college student, lived a quiet yet passionate life, immersed in manga and anime—until tragedy struck.

In a selfless act, he died protecting Akane Matsumoto, the one person who had always been by his side.

But death was not the end.

Yahiko is reincarnated as a baby in a mysterious fantasy realm called Eryndorath, reborn with fragments of his past memories still intact. In this new world, he finds something he had lost five years ago on Earth—a loving family.

Armed with the wisdom of his former life and a sharp, analytical mind, Yahiko—now known as Kyle Crimson—vows to grow stronger and protect the people he now holds dear.

But Eryndorath is no paradise.

Demonic entities stir in the shadows—Ruthless factions seek power at any cost. As Kyle begins to unravel the truth behind his reincarnation and the secrets buried deep within this magical world, he realizes that his new life may hold a greater purpose than he ever imagined.
