She appears in the Kuudere Simulator spin-off games and the "I Want My Senpai Back" video.^[2] Her name was stated as Kuudere-chan in the description.

Personality[]

“

The school librarian.
Strongly prefers solitude.
Very rarely expresses emotions.

”

— Description from Info-chan.

Among the Personas that are currently implemented in the game, Kuu is a Loner. If she sees a corpse or witnesses a murder, she will run out of school and call the Police. She cannot participate in physical fights against murderers. She will hide her face if Ayano Aishi aims her Phone at her.

Kuu is a kuudere. A kuudere is a common personality trope in anime that displays a cool and inexpressive behavior at first as they keep their emotions in check (Kuu), but over time adopts a lovestruck and expressive attitude (Dere).

At one point, it was planned that Kuu would have a unique reaction to murder. This, however, was a special case that applied only to her and Robot-chan and would be difficult from the programming side.^[3] This persona may have been called "Apathetic".^[4] This idea has since been scrapped.

According to YandereDev, Kuu is only pretending to be emotionless because she thinks that acting cold and distant makes her seem cool.^[5] The Death Demon's ritual also confirms this, as Kuu pretends to be emotionless to appear cool and mysterious when other people think of her.

According to YandereDev, Kuu's liking of violence is a "weird quirk of hers".^[6] She secretly has dark thoughts and wants to see violence visited on the people that she dislikes.^[7]

- Both girls were best friends with each other. Yui wanted more friends, but no other kid wanted to play with her. Kuu had an idea to allow herself to be disruptive to the other kids, and let Yui save the day by chasing Kuu away. Yui agreed and they acted on the plan, which resulted in Yui gaining new friends. However, when she tried to play with Kuu again, the latter rejected, citing that the kids will realize that Yui tricked them and will hate her if they saw both of them playing together. Yui was devastated that she lost the only real friend she had for a bunch of "superficial" friends she made. This incident stunted them from mentally developing properly.^[15]
