Fantasy Even After Coming Home!?

A seemingly ordinary boy named Shinichi suddenly finds himself dimension-drifting into a world of swords and magic. After experiencing tragedies, wars, and conspiracies, he finally returns to his original world on his own after a two-year journey. However, his homeland "Earth" has begun exchanges with "Gareste," an advanced alternate world where science and technology have flourished! Earth is gradually transforming into a modern fantasy where status-ism and advanced technology are becoming prevalent. The environments of his family and friends have changed due to years of separation and the world's transformation. Learning of these changes, Shinichi chooses to hide his "power" to avoid becoming a source of trouble and to live a peaceful, uneventful life. Even though he understands this is an impossible wish. Because he attracts chaos and has become far too accustomed to it. Above all, he was fundamentally a "meddlesome older brother" type. This is the story that began because he returned. ※Please note: The timeline is not in chronological order at first, so please use the numbers in the subtitles as a guide.
