Kuu Dere (real name: Kumi Demura) is one of the female students who currently attends Akademi. She also appears in a series of short game parodies, Kuudere Simulator.
Appearance[]
Kuu has chin-length dark pastel-blue hair and dark pastel-red eyes. She has the same skin tone as Ayano Aishi. Her bust size is 1.
She wears the default school uniform with knee-high white socks unless customized by the player.
In Kuudere Simulator, Kuu is pale, and her hair is more oval-shaped and longer.
Personality[]
The school librarian.
Strongly prefers solitude.
Very rarely expresses emotions.
Kuu hiding her face.
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 based on 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, adopt a lovestruck and expressive attitude (Dere).
In reality, though, Kuu is only pretending to be emotionless because she thinks that acting cold and distant makes her seem cool and mysterious when other people think of her.[2] Kuu's liking of violence is a "weird quirk of hers".[3] She secretly has dark thoughts and wants to see violence visited on the people that she dislikes.[4] 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.[5] This persona may have been called "Apathetic".[6] This idea has since been scrapped.

Relationships[]
Yui Rio[]
- Main article: Yui Rio
In 2015, YandereDev developed a backstory for Kuu and Yui Rio, which was based on the Japanese myth "The Red Oni And The Blue Oni". It was later scrapped as they now live in different time periods.
Both girls were best friends with each other. Yui wanted more friends, but no other kids 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 would realize that Yui tricked them and would 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 their mental development.[7]
Others[]
Kuu in Yandere-chan's Childhood.
- Ayano Aishi: Kuu met Ayano in high school[8] and thought of her as her friend.[9]
- Kumi, along with Midori Gurin are only students who need 25 friendship points in order to get befriended.
- Himeko Dereguchi: If Kumi and Himeko ever met each other, Himeko would get bored with Kumi very quickly and would leave to interact with someone more interesting.[10]
Trivia[]
- There was a bug in the January 15th, 2016 Build where she had Mai Waifu's portrait. This was later fixed in the February 1st, 2016 Build.
- YandereDev likes the idea of her repeating her quotes from Kuudere Simulator; however, this would require a lot of "special case" code.[11]
- She was implemented into Yandere Simulator in the November 15th, 2015 Build.
- As of the March 31st, 2018 Build, the edges of her hair were more defined with dark blue, but as of the April 26th, 2018 Build, that was no longer the case, and her hair was colored dark aqua. Her hair is derived from Honoka Futaba, a character that can be bought in the Unity3D Asset Store.[12]
- All of her dialogue in Kuudere Simulator, Kuudere Simulator 2, and Kuudere Simulator 3 appears as blue text.

- Her appearance is a reference to Rei Ayanami from Neon Genesis Evangelion.[13]
- She and Kokuma Jutsu are references to Rei Ayanami.
- She makes a small cameo in the gaming club by appearing on the dating simulator game screen.
- If YandereDev decides to have student nicknames, then her real name would not be Kuu Dere, and this would instead be a nickname given to her, due to her emotionless and apathetic nature.[14] He suggested "Kumiko Deremoto" as a hypothetical name for her.[15]
- As of a later update, Kuu Dere is now her nickname, and her real name is Kumi Demura.
- The ku part of her real name, Kumi, can be written as "long time" (久), "coming" (来), "nine" (九), or "crimson" (紅), while the "mi" part can be written as "beauty" (美), "fruit" (実), "not yet" (未), or "sea" (海).
- Her surname, Demura, means "to come out" (de, 出) and "village" (mura, 村).
