Futami Moriyama is a supporting character in the anime Recorder and Randsell. She works as an elementary school teacher and is the homeroom instructor for the main protagonist, Atsushi Miyagawa. Physically, she is an adult woman with brown hair that falls to her shoulders and brown eyes. Her standard appearance is characterized by her wearing glasses, a practical tracksuit, and sneakers, reflecting her active role within the school environment.

Born on April 3, Futami's professional background is central to her personality. Before her current position, she taught at an all-girls school, which left her unaccustomed to dealing with male students. This inexperience is severely tested by the presence of Atsushi in her class. Because Atsushi is an elementary school student who has the appearance of a fully grown adult, Futami often struggles to treat him like a normal child. She has problems and difficulties dealing with him, as his mature looks create a constant source of awkwardness and misunderstanding for her within the school setting.

Despite her professional anxiety, Futami is not depicted as a harsh or uncaring person. A notable episode in her development occurs during a cherry blossom viewing party. At this event, other characters encounter her in a very intoxicated state. While drunk, she takes the opportunity to express some personal feelings directly to Atsushi, revealing a more vulnerable and emotionally open side that her professional demeanor usually conceals. This moment provides insight into her internal conflicts and suggests she has genuine, if complicated, feelings regarding her unusual student. Her role in the story is primarily to serve as a source of comedic friction derived from the central visual gag of the series, highlighting the absurdity of Atsushi's situation from an authority figure's point of view.
