The title is a collaboration between the Ultra Kaiju, which appears in the legendary Ultraman action programs, and the monster breeding simulation title Monster Rancher, which will celebrate its 25th anniversary in 2022.

Based on the gameplay mechanics of Monster Rancher and Monster Rancher 2, the title is an Ultra Kaiju breeding simulation that allows you to raise your own Ultra Kaiju—whether it's an Alien Baltan, Zetton, or Gomora.

Raise your own Ultra Kaiju by selecting from a range of actions each week, such as feeding them, assigning training exercises, sending them on errands with rival Kaiju, and going on adventures!

On the ranch where you raise your Ultra Kaiju, you have the opportunity to observe the behavior of the Ultra Kaiju up close—a perspective that the original works do not allow. In tournaments, your Kaiju will compete against their rivals in battles that are just as intense as in the films.
