Reiji Ozora
Due to his short attention span, he is renowned as a lazy quitter that never keeps any of his promises and is nicknamed 'The Tardy Champion'. Blackmailed by Maiko, he was dragged to Dragon Drive against his will, but became obsessed with the game after his first taste of victory. He has the ability to tame almost any dragon. His dragon is Chibisuke.
Maiko Yukino
Reiji's childhood friend. She is always hugging and dragging Reiji to do things with her. She is tough and dislikes being patronized, often striving to prove herself as an equal to her comrades. She has a crush on Reiji that she is probably unaware of, and often gets jealous when any other girl appears to be showing signs of affection toward Reiji.
Daisuke Hagiwara
A fellow schoolmate of Reiji and Maiko, he initially holds a grudge against Reiji for stealing Maiko's affection, but the two eventually become close friends. He thinks of Reiji as a rival, but Reiji does not think much of him, especially after Reiji's victory over Daisuke in their first battle against one another.
Kyoji Tachiban
Known as Reiji's best friend he is an awesome Dragon Drive player who wants to challenge Reiji himself. He is impressed with Chibi's abilities. He is also the champion of a block.
Chibisuke
Light-elemental. Reiji's dragon and the long awaited savior of Rikyu. As Chibi, he appears to be the weakest dragon, but in his true form as Senkoukura, he is the most powerful of all dragons, and worshipped as a deity by some. He is also able to change his element such as dark or fire. He looks like a traditional European dragon, only upright, in his true form. His "chibi" form is a small dragon with tiny wings and fur. His strength and abilities can alter depending on Reiji's emotional state. His signature attack is a devastating blast of energy, "Lightning Wave", that destroys everything in its path.
