The twin siblings, Ohdo Yuhi and Ohdo Yuamu, who live in Mutsuba Town, are elementary school students who run UTS (Ultraterrastrial Trouble Solutions), a company that gets rid of somewhat dodgy and suspicious aliens. Yuhi struggles every day to build a mysterious device to make first contract with aliens… … Until that day!

In the middle of an authentic Crop Circle, the twins find a for-realsies Spaceship. Inside that vessel, they encounter the alien Yudias, who has come from the distant Velgar Star Cluster.

Now, one space soldier who has come from the edge of a far-off distant galaxy charges into a new battlefield, Rush Duels! Let’s go, GO RUSH!!
