SPRING 2022

Nagi Umino and Erika Amano, a studious high school student and a social media star, had nothing that linked them together—until they found out they were swapped at birth. When the sudden news is revealed to both of their families, their parents quickly devise a proposition with neither Nagi’s nor Erika’s knowledge: in order to restore them both to their rightful families and ensure everyone’s happiness, the two should get engaged.

When informed of this, Nagi and Erika are quick to reject the absurd plan, refusing to go along with their parents’ wishes. But, with neither party willing to back down, only time can tell where their relationship will go.

After inheriting the company from their parents, siblings Yuuhi and Yuamu Oudou have started to work at the Alien Trouble Consultancy, an organization that hunts aliens. Although they have never encountered aliens before, Yuuhi is desperate to meet one as he believes that an alien has stolen his important item, called the “Earthdama”.

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 Yuudias Velgear, an alien from the Velgear Star Cluster. As it turns out, Yuudias is seeking to learn about Rush Duel—a card game popular among elementary school students—as he believes that it will save his home from a long war.

With the siblings agreeing to teach Yuudias about Rush Duel, they eventually realize that their first contact with an alien may not be a random coincidence.
