The discovery of a portal to other dimensions marks the beginning of a new era in interstellar travel, allowing individuals to journey beyond our solar system's boundaries. Hoshiwatari Goro is one such adventurer who embarks on a quest to locate his father, whose whereabouts remain unknown. All he possesses is an old photograph as evidence of their relationship. To achieve this objective, Goro joins "YAT," a young space travel company that offers excursions to various planets. However, during his voyage, an unfortunate incident occurs, causing the destruction of his spaceship. As a form of reparation, he is obligated to work for YAT. This event sets off a chain reaction of cosmic escapades for Goro.
