The anime will take place in the birthplace of "Rush Duel," Mutsuba-cho. Siblings Yuuhi and Yuamu run UTS, a group that gets rid of troublesome aliens. One day they find a spaceship, and inside they find Yudias, an alien from the planet Belgar. Yudias has come to Earth to search for Rush Duel to hopefully lead him and his friends (who have been chased out of their star system) into a new future. However, Yudias himself knows nothing about Rush Duel. Yūhi then challenges Yudias to a duel.
