Like most petty villains Iwana thought that he was very powerful when in actuality he wasn't. He was very loyal to Orochimaru.
He wore a green-coloured shark-like top complete with a hood which resembled a shark's head, with an appendage on the back that resembled a dorsal fin and dark pants. He also had black-coloured eyes and two purple markings under each eye. He carried a giant shuriken on his back.
Kajika and his group attacked Naruto Uzumaki, Sakura Haruno and Sasuke Uchiha while they were waiting for Kakashi Hatake to finish his reconnaissance for the missing man Genmai who was kidnapped to lure Team 7 and mostly Sasuke. Kajika kidnapped Sakura and took her to his lair while he and Yamame fought Naruto and Sasuke. The two return only they were Naruto and Sasuke in disguise and he fights against them, but they were easily defeated.
- Iwana (岩魚、鮇) refers to several species of fish from the Salvelinus genus, known as char (or charr) in English.
