Despite being one of Zebrudia's few level 8 treasure hunters and the leader of the capital's top party, Grieving Souls, Krai Andrey does not deserve his prominent reputation.

Krai knows his success is only a series of coincidences, but the weight of those expectations grows heavier as time goes by. Unfortunately, as the other members of the Grieving Souls continue to shock the world with their achievements, Krai's wish for a peaceful retirement drifts ever further out of reach.

After inheriting the company from their parents, siblings Yuuhi and Yuamu Oudou have started to work at Ultraterrestrial Trouble Solutions, an organization that hunts aliens.

One day, while searching for extraterrestrial creatures, Yuuhi and Yuamu find a strange spot in the forest where many trees have fallen, forming a scenery similar to a crop circle. As they venture further, they discover a mysterious spaceship and enter it out of curiosity. To their surprise, they come across Yudias Velgear, an alien from the Velgear Star Cluster.
