イト

Ito is one of Kuro's childhood friends and watched him grow up, making him play the role of a big brother. He's happy to see him mature but also feels rather lonely about it sometimes.

Race: Yellowfin Tuna (Hence why "4" in human years is an adult age for him)

Special skill: He can jump higher than even seagulls

Origin: Somewhere overseas

Favorite time: When young children are happy
