Sendou Nana

She suddenly barges into the apartment where the main character works, declaring herself his wife.

She is a cheerful and healthy type. An orphan of unknown birth, she was raised as a servant in Mishio's Swiss villa from an early age.

She has had feelings for Yamato ever since he saw a movie starring the young Yamato when he was a child (which, of course, Mishio forced her to see).
