Sandayū Asama

was a character in Naruto the Movie: Ninja Clash in the Land of Snow. He acted as a personal assistant for Koyuki Kazahana, formal administration assistant. When Doto Kazahana and his ninja attacked, he died together with a lot of local forces. Doto's ninja took him out with shooting of tons of kunai knives.

We can assume he was a samurai, since he fought with the forces as their leader and in a samurai uniform. Also he told Doto he was once part of the 50th Brigade, which was probably some fighting legion.

He also shows that he cares for Koyuki Kazahana enough to die for her and tell her not to cry when he died.
