A calm, cool boy with a penchant for being idiotic. He frequently uses idioms while speaking but tends to incorrectly quote them. He's a member of Team V who meets Nagi and Reo during Blue Lock's First Selection. Nagi and Reo dub him "Baka Zantetsu" but he dislikes being called stupid.

Despite Zantetsu's lack of intelligence, he remains determined to achieve his goals. His weapons include his fast acceleration time and precisely shooting with his left foot.

Zantetsu's glasses don't actually aid his vision; he only wears them to look smart.
