Ui Tunesu

Ui Tunesu (a.k.a Witness-chan) is one of the female students who attended Akademi in 1980s Mode.

Background[]

When YandereDev was asked the reason why Ui cares a lot about justice, he gave a thorough explanation:

She had one negative experience previously in her life. It was in high school. A student in her class did a bunch of bad things for an entire school year - stealing classmates' belongings, pouring water over their stuff, putting dirt on a student's flute so that when the student played flute they would taste dirt, etc. This student did all of these things in secret; nobody was ever able to catch them, not until the end of the school year. It was Ui's best friend, who was doing these things to "get revenge" on anyone who bullied her.

Ui realized that she can't really trust anyone, because even your best friend might be lying to you and hiding a bunch of bad behavior. She saw a bunch of "clues" that her friend was the one responsible for the bad behavior, but chose to ignore it. After that, she became extra vigilant and always kept an eye out for weird or suspicious behavior, not wanting to let the situation with her best friend repeat itself ever again.^[2]

Appearance[]

Ui wears the default 1980s uniform along with a dark gray apron with stars and lines drawn on it.

She has lower-back length messy scarlet hair tied into twin tails and scarlet eyes. Her bust size is 1.^[3]

Prior to her initial removal from the game, she wore the default uniform.

When she was re-implemented in the October 17th, 2019 Build as a street background character, she was seen wearing a maid outfit.

Personality[]

“	A girl who is utterly incapable of minding her own business. Always personally investigates people who she suspects of doing shady things, which has earned her the nickname of 'Witness-chan.	”
	— Description in Ryoba's notebook.

Among the personas that are currently implemented in the game, Ui is a Snitch. If she sees a corpse or witnesses a murder, she will run to the landline phone in the Faculty Room and call the police. She cannot participate in physical fights against murderers.

Stated by YandereDev, Ui is nosy, always interested in other people's business. Part of this is because she enjoys gossip. Another part is that she knows what kind of horrible things people are capable of, so she is kind of fearful of people in general.

YandereDev states that Ui is very friendly and got along with everyone well.

Scenes[]

Ui first appeared in the "How to Get Away with Murder in Yandere Simulator" video. In the video, she witnessed Victim-chan being murdered by Ayano Aishi. She then ran out of the school and called the police. She was later murdered by Ayano and left on school grounds along with other evidence. This ultimately caused Ayano to be arrested by the police due committing murder without disposing of the evidence.

She briefly appeared later in the January Osana Progress Report - Part 1 and Making Senpai Reject A Love Confession In Yandere Simulator videos, where she witnessed Ayano poisoning Osana Najimi's bento.

She appeared again in 1980s Mode. She was an important part at the tutorial, as she saw Ryoba take a knife from the Cooking Club, showing the new players how to apologize to a student, preventing losing a lot of Reputation. She is also quite important at the end of the game, since she told the police everything she witnessed Ryoba do, giving The Journalist enough evidence to accuse Ryoba of murder.

Routine[]

Regular[]

At 7:05 AM, Ui enters the school grounds. She walks to her locker at 7:10 AM and changes from her outdoor shoes to her indoor shoes. At 7:15 AM, she walks to the Cooking Club and prepares a slew of desserts with the rest of the members there. She then travels around the school to give the strawberry shortcakes to various students.

At 8:00 AM, she walks into Classroom 1-1 and sits at her desk. She starts her morning classes at 8:30 AM, and leaves the classroom at 1:00 PM. During lunchtime, she goes and has lunch with the other cooking club members.

She walks back to class again at 1:30 PM and participates in cleaning time between 3:30 PM and 4:00 PM. Afterward, she heads to the Cooking Club and stays there until the end of the day. If Ryoba joins in club activities, she will prepare a meal from 5:30 PM to 6:00 PM.

If the Cooking Club is disbanded, Ui will socialize with the other former members in the Home Ec Room during periods in which she would normally attend it.

Tutorial[]

Ui stands outside the incinerator gates and asks Ryoba why she took a knife out of the cooking club. After making an excuse and apologizing to her, the time will reach 5:59 and she will vanish.

Previous[]

Ui had a different routine from all the other students, being placed at the front of the school so she would be able to see Victim-chan's death. Her routine included standing in a corner where she could witness Victim-chan being murdered. She was kind of like Kokona Haruka, a test subject, but less complex.

When she was in town, she stood outside the Maid Café in the town doing the idle animation of the "Akane" pose.

Topics[]

The topics towards Ui are Negative/Positive/Neutral as follows:

Positive	Negative

Cooking Cats Justice Gossip Socializing	Occult Martial Arts Jokes Violence Solitude

Relationships[]

The Journalist[]

Ui is probably seen as trustworthy by the Journalist, when he mentioned everything Ui told the police that she witnessed Ryoba do at court for Ryoba's case.

She initially thought that the Journalist was a good guy. However, by the end of Ryoba's court case, she became permanently hostile towards the Journalist when Ui began to feel that he was actually a bad guy as a result of Ryoba's lies and being declared innocent.^[4]

Student Council[]

Ui always felt that the student council were lazy and doing a bad job, since so many suspicious or dangerous things were happening around school and were doing nothing to stop it. She did, however, warn them about Ryoba's presence at the school, telling them each and every suspicious detail that she saw from the night of Sumire's disappearance. This explains why they are cautious around Ryoba.

Ryoba Aishi[]

Ui was suspicious towards Ryoba when she witnessed her doing something off. She told the police everything she witnessed Ryoba do.

However, after Ryoba was declared innocent in court, Ui felt a tremendous amount of guilt for providing the police with information that led them to suspect Ryoba of murder and felt responsible for all of the negative media attention that had entered Ryoba's life. She personally apologized to Ryoba for what she had done. Ryoba was originally planning on killing her before then, but now knowing Ui wasn't a threat, she let her live. Afterwards, Ui decided to stop snooping around in anyone else's business or accuse anyone of anything ever again.

Trivia[]

Her expression was the first to be traumatic, more specifically her reaction to seeing murder.
Although she was removed before strength was introduced, it can be guessed that she was incapable of self-defense because Ayano Aishi was able to easily kill her in the videos in which she appeared.
- This was later proven to be true in 1980s Mode.
She was initially removed from the game along with Victim-chan because they only existed for the sake of demonstrating a game feature in one video and because they weren't fully fleshed out characters.^[5]
Her initial existence in the school may be proven by looking at the JSON files from some old builds (from March 1st, 2015 to April 8th, 2015) and in videos posted by Yandere Dev in the past.
She was formerly in the Gardening Club and in Classroom 1-2.
The personality described in the profile would be more like to the Sleuth persona, and yet she has the Snitch persona.
Her first hair model was the same as Tsundere-Chan's, and Saki Miyu's first hair model.
YandereDev states that she had warned the Student Council that Ryoba Aishi might be a dangerous person, possibly due to witnessing her carrying a knife in the previous day, which could explain why they appear to be also suspicious at Ryoba.
- This is similar to the Student Council in 202X Mode are suspicious of Ayano since they were told by Megami Saikou to keep on eye on her.^[6]
When pronouncing her name, it sounds like Witness because Wi in Japanese is pronounced as Ui and Tness is pronounced as Tunesu (Witness-Uitunesu).
- Her name, 'Uitunesu', is a Japanese word that means "witness" (ウイつねす).
She along with Raimu Ichijo and Koharu Hinata are the only female students in Classroom 1-1 in 1980s Mode who can't be sold to The Yakuza.
YandereDev confirmed that Ui became an office worker, then married and became a mother.
- She was the first non main character in 1980s Mode to be confirmed to still be alive in the main story mode.
