At fifteen, Saito was transported to a parallel realm where he rose to become the legendary Great Sage, ultimately vanquishing the Demon Lord. Just as his journey seemed complete, a portal reopened, allowing him to return to Earth—only to discover that nineteen years had passed in his absence. Now an adult in a world that moved on without him, he reunites with Kanako, his childhood friend, who has since become a single mother. Yet, lurking in the shadows is an unknown threat targeting Kanako’s life. Despite yearning for a quiet existence, Saito’s extraordinary abilities from his otherworldly adventures may be the only thing standing between her and danger. Thus begins the tale of a reluctant hero, torn between his desire for peace and the responsibilities of his past.

Though he dreams of a simple existence, fate has other plans. With every step, Saito is pulled deeper into a hidden conflict, one that threatens not just Kanako but the fragile peace he seeks. His journey from hero to ordinary man is anything but smooth, as the shadows of another world refuse to let him go. The story unfolds with quiet tension, blending nostalgia, danger, and the struggle of a man caught between two lives.
