A group of humans and their digimon found themselves in the Digital World. They soon found a threat under the name of Barbamon overthrowing the peace of the world. Taking matters into their own hands, the group decided to seal Barbamon and his army away. Though the seal was unstable, in the meantime they decided to gather up other tamers that ended up in the Digital World to help them fight against Barbamon and his army if and when the seal were to be broken.
This group of humans are known as Ultimate Tamers.
