Zenza

is one of the young monks-in-training at the Fire Temple.

Hidan and Kakuzu arc
Zenza was on patrol in the outskirts of the temple during the attack of Akatsuki members Hidan and Kakuzu. Losing Chiriku and his fellow comrades came as a great shock to him upon finding out what happened to them.

He is one of only four known monk survivors in the attack, along with Bansai, Sentoki, and Sora.
