Lead/Protagonist role.
Voice Inspiration: Yor Forger (Spy x Family)

Chiyumi speaks with a lack of confidence, always trying her best to sound elegant and relaxed, ending up rather monotone at times, like someone struggling to keep up their customer service voice. 

Chiyumi doesn't think highly of herself, Often putting herself down and belittling her achievements. To Put it simple, Chiyumi is Insecure and tends to be quiet, but when she has a strong opinion she says it out loud. Chiyumi is a highly secretive person due to her tendency to mask her true emotions around others. She presents herself as mysterious, and it's quite rare to see her with a smile.
