Ikasama, a cunning gambler skilled in deception and fraud, is frequently depicted with dice in hand, orchestrating swindles. His Japanese name, meaning "swindler," reflects his deceitful nature. Renowned for light-footed agility, he bears the nickname "swift runner" for his capacity to evade capture through rapid, elusive movements.

Joining Gamba’s group in their mission to defend Yumemishima Island against the Noroi Clan, he contributes sharp wit and speed to the team’s strategies. His role centers on employing trickery and reflexes to outmaneuver foes, though documented media does not delve into his personal history or internal growth.

The 2015 3D CG film adaptation preserves these traits while localizing his name as "Ace" in English releases. Sources remain silent on his origins, relationships, or evolution beyond his established persona across original and adapted narratives.
