The story follows a boy named Genki Sakura, who is a key player of the Monster Rancher video games.

The Magic Stone leads them to Golem, Tiger, and Hare, each of which have their motivations to join the group on their journey to find the Phoenix.

In their travels, the gang befriends and aids many monsters as they continue searching, unlocking as many Mystery Disks as possible in the hopes of finding the Phoenix.

The two monsters seemingly die, and Genki is knocked back into the real world in the resulting explosion, comforted by visions of his friends as he goes home.

The second season consists of Genki returning to the Monster World to revive and reunite his friends, who were turned into disks and separated after the fight with Moo.
