Friends with Noelle, Berdly, and Ralsei, and best friends with Susie. He secretly harbors feelings for Susie. In the Dark World, his skin turns blue. He carries a sword, wears armor, and has a scarf around his neck. He cannot use magic. He acts as the leader of the team, giving instructions to Susie and Ralsei.

A tomboyish delinquent girl with long hair. A monster and a Lightner. First person: I (rough) or I (feminine). She likes spiky things and the giant monster "Suszilla." She is close friends with Lancer and Kris's best friend. She actually likes Noelle. She grows a tail in the Dark World but keeps it hidden. Her weapon is an axe. She often wants to attack during battles with Darkners, but Ralsei stops her. Her specialty is the Rude Buster, a violent magic spell that fires a purple slash. She was taught the healing spell Ultimate Heal by Ralsei, but because she hasn't mastered it, the amount of healing is very low.

He claims to be the Prince of the Dark World, though whether this is true is uncertain. He likes Kris and Susie as friends. It is unclear what he thinks of Noelle. He gets embarrassed when called "cute." If his glasses are taken, he says, "Give them back!" He dislikes fighting. His specialty is the healing spell Heal Prayer. He uses fire magic when baking cakes, but keeps it a secret from everyone. He was taught how to be sarcastic by Susie.
