Sandayū Asama

was a personal assistant for Yukie Fujikaze, who appeared in Naruto the Movie: Ninja Clash in the Land of Snow.

Background
It was later revealed that he was once part of the 50th Brigade.

Plot Overview
Sandayū hired Team Kakashi to escort Yukie to the Land of Snow. He suggested this location to Yukie's movie director, so that he could bring her back to the land and make her the heiress of the throne which Dotō Kazahana had stolen.

When they reached the Land of Snow, Dotō arrived at the movie set. Later, Sandayū led a group of samurai to attack Dotō, in the hopes of avenging the late daimyō Sōsetsu Kazahana, Dotō's brother and Koyuki's father, which the latter was killed ten years ago. However, Dotō's ninja subordinates launched multiple waves of kunai from their mortar-mounted train compartments, massacring the entire brigade. Later before his death after Dotō's retreat, Sandayū managed to tell Koyuki not to cry for him with his dying breath.

After Dotō's demise and the new land became the Land of Spring, Koyuki became the new daimyō and saw the vision of Sandayū and her father until they disappeared.
