Saki Miyu, whose real name is Saki Mayuzumi, is one of the female students that currently attends Akademi High School.


Saki Miyu wears the default female school uniform unless customized by the player. Her eyes are cyan. She has fair skin and the second largest bust size in the game, at 1.8. Her hair is cyan; it is styled into long pigtails that reach her elbows. Her bangs are swept to the left. Some shorter pieces of hair hang down the sides of her head and curl inwards towards her face. As a member of the Cooking Club, she wears a purple kerchief and a matching purple apron patterned with small hearts. If the Cooking Club is disbanded, Saki will remove her kerchief and apron for the rest of the game.


From her implementation in the March 1st, 2015 Build until the February 8th, 2016 Build, Saki had light cyan eyes and cyan twintails that YandereDev created using the model for Ayano's ponytail in a bigger size.

From February 8th, 2016 Build until the March 1st, 2017 Build, Saki had dark cyan hair with short bangs swept to the right and slightly bent locks framing her face; the rest of her hair was left parted and tied up in twintails that ended in spirals.

In the January 16th, 2017 Build, friendship bracelets were added to the right wrists of the Rainbow Six girls. Saki's is cyan.

From the February 2nd, 2017 Build to the August 18th, 2018 Build, Saki wore cyan stockings and panties.

From March 1st, 2017 Build to the August 18th, 2018 Build, Saki had thick cyan twintails ending in spirals held by two bright cyan bands, short bangs meeting in the middle of her forehead, curled locks framing her face, and a small ahoge at her part.

From the March 18th, 2017 Build to the August 18th, 2018 Build, her eyes were a brighter shade of cyan.

From the August 18th, 2018 Build to the December 3rd, 2018 Build, Saki's hair returned to thinner spiral twintails reminiscent of her 2016-2017 hair; however, her face-framing locks were shortened and curled at the ends, her bangs were brushed straight forward and not parted, and the shade was made slightly more green. A purple Cooking Club kerchief was also added, along with a light pink polka-dotted apron. Her cyan thigh-high stockings, panties, and friendship bracelet were removed.

As of the August 22nd, 2018 Build, Saki's cyan friendship bracelet was restored.

As of the December 2nd, 2018 Build, Saki's apron is a polka-dotted purple that matches her kerchief.

As of the December 3, 2018, Build, Saki's hair has been changed. She had thicker, more textured, spiral ringlets on either sides of her head. Her bangs are straight and blunt, cute neatly to her eyebrows. Her face-framing locks are more layered; her kerchief is also slightly lighter and her facial details were changed to give the appearance of blush and subtle pink lip gloss.

From the January 17, 2019, Build to the February 1st, 2019 Build, Saki's eyes and eyelashes were a noticeably brighter and more vibrant cyan.

As of the February 1st, 2019 Build, Saki's eyes and eyelashes have been reverted to a darker, more subtle, cyan.

As of the March 31st, 2020 Build, her hairstyle was changed again, and it now resembles one of her hair's earlier versions. Her twintails are straight, her bangs become partially side-swept, and plum purple scrunchies now hold her pigtails in place. Her facial details have also been reduced somewhat.

As of the September 16th Build, Saki's hair has changed once again.

As of April 2nd, 2021, Saki's new hair texture was recolored to have a green tint. Since it got negative feedback from fans, it was recolored again as of June 1st 2021, but still had the green tint. Finally, as of June 16th, 2021, her hair color was reverted back to the one from the September 16th, 2020 Build, but with a different eye texture.



"Loves sweets, candy, and desserts. Never gets fat, no matter how much junk food she eats. Kokona Haruka's best friend and closest confidant. Kokona is likely to discuss personal matters with this girl."


Saki striking a cute pose.

Among the personas currently implemented in the game, Saki is a Social Butterfly. She will happily pose for a picture if the player aims their camera at her. If she sees a corpse or witnesses a murder, she will run to the nearest secluded area and call the police. She cannot participate in physical fights against murderers, unless they kill Kokona Haruka.

She loves sweets, candy, and desserts. She never gets fat, no matter how much junk food she eats.

During lunch at the rooftop on Monday, Saki will talk with Kokona Haruka about what she assumes is domestic abuse from Kokona's father. Saki is presumably compassionate and an understanding friend and will only show concern for Kokona.

If Saki hears or reads about Kokona's compensated dating, she will be surprised. She has never shown to be caring for Kokona when she gets bullied, so it's possible that Saki isn't the greatest friend. YandereDev might add comforting animations towards Kokona, but there may be a limit: if Kokona's reputation is bad enough, Saki's may go down too and she would have to avoid Kokona.[2]

Saki preparing food.

At 7:05 AM, Saki 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 food with the rest of the members there. She then travels around the school to give the food to various students.

At 8:00 AM, Saki 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. On Monday, she goes to the rooftop to talk with Kokona about Kokona's family issues. On all other days, she eats lunch with the rest of the members of the Cooking Club.

Saki 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 Ayano joins in club activities, she will prepare a meal from 5:30 PM to 6:00 PM.

If the Cooking Club is disbanded, she will socialize with the other former members outside of the club during periods in which she would normally attend it (7:15 AM, and 3:30 PM).

As of March 22nd, 2021 Build, Saki spends her time conversing with Kokona instead of spending her time at the Cooking Club and giving food to students. At 7:00 AM, she runs to her locker and changes her shoes, then quickly runs outside the school gates a bit far as their hanging spot where she will converse with Kokona. At 7:09 AM, she and Kokona will move to the rooftop to socialize.


Main Article: Tasks

Saki's task is to find her bra. Her bra has been near the Confession Tree against the fence, both before and after the November 15th, 2015 Build. Once the player collects and brings it back to her, Saki will be very happy and will become Ayano's friend.


Due to Kokona's family debt, Saki tried to help them make money. She attempted to sell her underwear to boys. At one point, she tried to sell her bra, but could not go through with it and threw it over the fence, which is why the player has to retrieve it for her in order to complete her task.


Kokona Haruka

According to her Student Profile, Saki Miyu is Kokona's best friend and closest confidant. Kokona is willing to discuss personal matters with her, such as during the rooftop conversation about her family problems on Monday.

As of the October 31, 2019 Build, Saki will attack Ayano if Kokona is murdered in front of her. The same goes for Saki being killed in front of Kokona. Still, they are incapable of defense so the player will never lose against them in a struggle minigame.

Well...actually...there is something that I need help with...This is ...really embarrassing...but...well...I lost...my bra...somewhere at school...and I can't find it anywhere... D-Don't ask me why my bra is missing! It's a long story, okay? The point is, if you find a bra lying around, it's mine, and I would really appreciate it if you'd return it to me! Oh, god...this is so embarrassing...
— Saki asking Ayano to find her lost bra.
You'll look for it? Thanks! I hope you find it...
— Accepting her task.
Ugh...why did I even bring that up...
— Denying her task.
Yes! You found it! Thanks a lot - I owe you one!
— Completing her task.
You haven't been acting like your usual self lately. Is something bothering you? If you don't want to talk about it, that's fine...but remember...I'm your friend, and I'd never judge you for anything. I'm listening. What?? That sounds really serious! What does your dad do? You don't have anything to be ashamed of! Just tell me what's wrong! If you say so...but now I'm really worried...
— Saki during her conversation with Kokona on the rooftop.
Wow, lame. Don't post stupid lies on the internet.
— Saki Miyu not believing Ayano's lie on the Internet.
