A bishoujo prisoner who seems to be cut off from the rest of Japan, and has an air of transparency. She appears to be indecisive but is actually very blunt with her words, and can’t accept being in the unusual situation in MILGRAM. When meeting Es, she appeared very wary. Her seemingly well upbringing suggests that she was likely born into a fortunate family. Either due to this or her high pride, when she runs into conflicts with others, she immediately starts to cry or whine. -From the MILGRAM Wiki

ojou-sama princess type, but i feel as if she sounds like fischl genshin impact. extremely dramatic, very easy to flip sides, so looking for a medium-high female voice (with sort of a stuck up tone? like a voice that kind of makes you want to hate her... lol) i think experience from voicing tsunderes will come in handy here. (also she's half french so feel free to try it with a SLIGHT accent)
