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 is celebrating its 25th anniversary in 2022. Using the game system of Monster Rancher and Monster Rancher 2 as its base, the title is an Ultra Kaiju breeding simulation game, which allows you to raise your very own Ultra Kaiju – be it an Alien Baltan, Zetton, or Gomora. Raise your own Ultra Kaiju by selecting from a range of actions each week, including feeding them, assigning them training drills, sending them on an Errantry with rival Kaiju, and going on adventures! At the ranch where you raise your Ultra Kaiju, you will have the opportunity to observe the behavior of the Ultra Kaiju up close – an approach that the original works do not allow. In tournaments, your Kaiju will face off against rivals in battles every bit as intense as in the movies.
