Natsume was born in a family of poor farmers. In his youth he used to work as a servant at a garden tree house, where he learned of his ability for the first time. He now serves Yukina. In public they have a formal relationship to keep up appearances, but otherwise they treat each other as equals, although Natsume tends to stay faithful to her.

He has a very honest and sincere personality, but has his klutzy moments at the time.

His ability works like a telephoto lens, and he is also able to see in the dark as if he has night vision. His power excells during moonlit nights.
