Maki is a student of the Ultimate Academy for Gifted Juveniles, and a participant of the Killing School Semester featured in Danganronpa V3: Killing Harmony. Her title is the Ultimate Assassin, but, she did lie and claim her title was Ultimate Child Caregiver.
In Maki's Love Suite scene, her fantasy includes her and a friend from the same orphanage as her. They have known each other for ten years and when they were younger, her friend mentioned he wants to make a real family with her while they were playing house. Maki says she never noticed her friend is in love with her and she is confused by her own feelings as well, but she realizes she likes him too. She simply wants to stay close to him and asks him to promise he will always be with her.

Maki's English voice actress, Erica Mendez, also provides the voice of Nagisa Shingetsu in Danganronpa Another Episode: Ultra Despair Girls.
