Suna Assassin Captain

is the captain of the Sunagakure ANBU assassination squad.

Appearance
Shiro wears what appears to be the standard attire for the Suna ANBU. This consisted of the regular Suna-nin attire albeit a sleeveless shirt and a mask that is reminiscent of a oni.

Abilities
Being a puppet user, Shiro employs the use of puppets. He can combine water release with certain puppets to spew water at opponents trapped in chakra threads. This is effective against sand users as it decreases the opponents ability to use sand.

Konoha History Arc
During a joint mission with Konoha, Shiro's squad was ordered to kill Gaara. Using his Puppet Water Release: Dance of Mystic Rain technique, he prevented Gaara from manipulating his sand. Gaara was saved by the arrival of Naruto Uzumaki and his team-mates, Yaoki and Korobi. Shiro and his squad were defeated when Gaara used a non-lethal ball of sand to incapacitate almost every member of the assassination squad.
