Shinichi, a seemingly ordinary boy, suddenly drifted across dimensions into a world of swords and magic.

After a two-year journey there, during which he experienced tragedy, war, and conspiracies, he returns to his original world by his own power, but

his home, "Earth," had begun exchanges with "Galest," another alternate world with advanced scientific technology!

Earth, where status-based society and advanced technology are beginning to run rampant, gradually transforming into a modern fantasy.

Shinichi, learning of the changed circumstances of his family and friends due to years of separation and global transformation,

dislikes becoming a source of trouble and, wanting to lead a peaceful life, chooses to hide his "power."

He understood it was an unfulfillable wish. After all, he attracted trouble and was far too accustomed to it.

More than anything, he was, at his core, an "overly helpful older brother."

This is the story that began because of his return.
