Momoka Amamiya is a supporting character in the My Daemon anime series. She is the daughter of Dr. Reiji Amamiya. Her background is marked by the death of her mother, who was killed by a daemon. This traumatic event caused Momoka to develop a strong hatred and fear of daemons. She is an eleven-year-old girl with black hair worn in braids and dark eyes. Her personality is shaped by this fear, often making her seem harsh or mean in situations that involve daemons. She displays a tsundere-like attitude, particularly in her interactions with the protagonist Kento. Her primary motivation is her fear of daemons and a desire to protect herself and her family from the danger she believes they represent. In the story, Momoka appears during the Nagoya arc, where she encounters Kento and Kaede. Her relationship with her father Reiji is close, as he is a doctor and she is his only daughter. She does not possess any special abilities or powers; she is an ordinary child living in a world transformed by the collision with Hell. Her development involves confronting her ingrained prejudice through her interactions with Kento and his daemon companion Anna, though the extent of her change is limited to her brief appearance in the series.
