Sanda

In a near-future Japan suffering from an extreme decline in the birthrate, children are considered the most precious to the whole nation. But for their security, they monitored them and put them in a boarding school. The legend of Santa has ended;  now he has a threat to the children. On a snowy December 25th, middle-school student Kazushige Sanda is attacked by his classmate Fuyumura, and she knows the secret about him that he is the descendant of Santa. She begs him to find her missing friends, Ono. Santa, please find him. After that, Sanda decided to become Santa Claus and protect the children from the adults.
