Miaya Gekkogahara is a character featured in Danganronpa 3: The End of Hope's Peak Academy - Side: Future.
Miaya was seemingly one of the people who participated in the Final Killing Game, but she was later revealed to be a robot controlled by Monaca Towa, with the real Miaya Gekkogahara having been murdered before the Final Killing Game. Monaca uses her to infiltrate the Future Foundation.
The puppet lacks any sentience and only acts as a puppet Monaca controls. She only speaks through her avatar, Usami.
Monaca later gives up control of Miaya, and control of her is briefly taken over by Komaru Naegi before entering an autonomous mode. In this state, she battled Kyosuke Munakata and was ultimately destroyed, with her data on all the participants' NG Codes being stolen by the latter.
Miaya is a short woman with blue hair, held by a light gray headband. She has blue eyes and long eyelashes. She wears a gray headphone and a long, dark red scarf which hides the lower part of her face. She wears a pale brown jacket, a black vest, a white dress shirt, and a black skirt. She also wears long black socks and white slippers. Her facial expressions never changed and her eyes lack emotion, but this may be because her eyes are actually cameras for Monaca Towa to view the events of the Final Killing Game.
Similar to her controller, Monaca, Miaya uses a wheelchair equipped with a modern PC screen, which is where Usami appears.
Miaya is a mysterious character, all that is currently known is that she is extremely shy and thus doesn't speak verbally. According to Aoi Asahina, she speaks only through her computer via Usami. Through Usami/Monomi, Miaya is far more proactive, as she was the one who proposed finding everyone's NG code, as well as being angry at Juzo Sakakura for attacking Naegi.
While her avatar Monomi is very emotional, Miaya's facial expressions never seem to change - while her mouth is hidden by her scarf, her eyes are visible and always have the same calm expression which lacks emotion. She also dislikes direct contact with other people. All of this, along with the fact that she never speaks, is most likely due to the fact that she's later revealed to be a robotic puppet.
She can act child-like at times, most likely because her avatar Monomi and the fact that she's controlled by Monaca. Everything Miaya says (through Monomi) or does is all Monaca's doing. She does not feel anything and has no personality of her own.
