The series stars Enta, a boy who has dreams of becoming the strongest pokémon trainer, but due to his lack of skill and the fact that he's a rookie trainer, he constantly loses. But with the help of Rald, an experienced trainer (also his training master), and Mitsuki (a pretty boy), who is forced to help Enta whenever he wants to participate in a double battle. The owner of the Battle Frontier Enishida (a.k.a. Scott) who introduces Enta to the Battle Frontier and occasionally gives him pointers on how to be a good trainer. The series doesn't seem to follow any regular story line (fighting to obtain the symbols in this case for example) but instead is more focused on putting Enta into a random set of adventures. Following Enta is a mysterious photographer who turns out to be the strongest Frontier Brain: Salon Maiden Anabel.
