Takashi Iwato is a defender who plays for Inakuni Raimon before joining the Inazuma Japan national team in Orion no Kokuin. He possesses a well-built frame, a large square head, small black eyes, and short dark-teal hair. In casual attire, he typically wears an orange sweater and knee-length jeans, creating an initially imposing impression.

During Orion no Kokuin, Iwato contributes to team discussions about Ichihoshi Mitsuru. Following Inazuma Japan's victory over the Eternal Dancers, he helps reveal information about Ichihoshi alongside Endou Mamoru. Endou had received additional context from Kimura Yousuke. This revelation occurs after Nosaka Yuuma exposes Ichihoshi's attempt to frame him for doping by switching the planted evidence.
