Io (イオ) is a character in the anime and manga series Battle Spirits Double Drive.
"Come, wild soul! Dispose of all enemies with your heroic horns! Summon! The OxTwelveGodKing Avalanche-Bison!"
- Io's Catchphrase while summoning OxTwelveGodKing Avalanche-Bison.
Io is a large and muscular man with dark skin. He has long gray and white hair and wears a red headband with gold horns. He wears a brown shoulder plate with gold horns on his left shoulder. He wears mostly gray clothing and has large black boots.
Io is serious and confident in his skill. He is also courteous and a good sport.
Io is a white hero from the world of Baschana. He is the owner of The OxTwelveGodKing Avalanche-Bison.
Io was called to the Spirits World to fulfill the prophecy of the dragon child. After Tatsumi, the dragon child, allowed for the usage of Ultimates to gather the God-Kings, Io was summoned by the Spirits World to lend his strength and serve as the white shield for Tatsumi.
Kiki Beresia challenged him to a battle to test his power. Io won and received Kiki's God-King as per the rules of the battle, but he returned it, as he believed that allies shouldn't fight each other.
He later encounters Shunta Mogami and Mei Merryhadda, who tries to convince him to join them in order to fight Tatsumi. However, Io wanted to find out what place he had in the prophecy about the dragon child as the white shield, and decided that to do so, he must use his God-King to defeat them. He fought Shunta and lost, thus losing his God-King. Even so, he declined Shunta's request to join them, as he wanted to see to the end of the prophecy at all costs.
Io uses a white deck. It has contained at some point the following:
|The TenthArtifactSacred Shine-Griff||White||Spirit|
|The OxTwelveGodKing Avalanche-Bison||White||Spirit (Burst Seal)|
|The GroundDeityBlade Ootenta||White||Brave (Soul Burst)|
|No. 18 Good Luck Well||White||Nexus|
