The series is set in a world where humans have been transported to a fantasy realm, and follows the story of Haruhiro, a young man who finds himself in this new world with no memories of his past. He joins a group of adventurers, known as the "Silver Streak", and together they embark on quests and battles against monsters and other threats.
The series is known for its unique blend of fantasy and isekai elements, as well as its exploration of themes such as identity, community, and the human condition. The anime adaptation, which consists of 12 episodes, was well-received by fans and critics alike.
