The lyricist of Nightcord at 25:00. She's the only member of the group who attends daytime classes. She seems to have no flaws whatsoever... or is she just putting on a facade?

Mafuyu is admired for her smarts, athleticism, and the humble sincerity she shows when she is praised for these talents. She is known to be kind, generous, and considerate, her words always polite and her voice being soft and warm. She is difficult, arguably impossible, to anger, for any hesitation she shows that might portray disagreement or displeasure is immediately covered with a gentle smile. Others are not afraid to rely on her, and they often have high hopes for her, knowing that she has met expectations before and will continue to do so.

To everyone else, Mafuyu is a "good girl." However, to herself and the other members of her unit, she is dispassionate, largely lacking in emotion and empathy. Her true self being lost a long time ago, she is desperately searching to find herself once again. Mafuyu’s personality underneath her facade is considerably more cold and blunt. Her voice is dull and her face is flat, both holding little feeling. She speaks few words, and the words she does speak tend to be no more than what is necessary. While she is not pleasant, polite, or "good", she is honest, and it is only within her cold honesty that her true feelings are given the slightest chance to show themselves. The other members of Nightcord at 25:00 recognize this in their willingness to offer a space where she can be "rehabilitated."

Her voice in her good girl persona is warm, friendly, and mild-mannered. Her natural voice is lower, dull and emotionless.

Please note: This dub will pronounce "Nightcord at 25:00" as "Nightcord at 25 o' clock".
