Saki Miyu

Saki Miyu is a female student that currently attends Akademi High School.

Appearance
Saki Miyu wears the default female school uniform, unless customized by the player.

She has two long, thick, cyan ponytails and bright cyan eyes. She has fair skin and the second largest bust size in the game, at 1.7.

In the future, Saki will gain cyan-colored hair with short bangs swept to the left, the rest of her hair kept up in two long pigtails in the back that end in spirals. Her eyes will be a darker cyan.

Personality
Among the personas currently implemented in the game, she is a Social Butterfly. She will happily pose for a picture if the player has their camera out. If she sees a corpse or witnesses a murder, she will run to the nearest crowd and call the police. She cannot participate in physical fights against murderers.

During lunch at the rooftop on Monday, she will talk with Kokona Haruka about domestic abuse from her father. Saki is presumably compassionate and an understanding friend and will only show concern for Kokona. Besides the Monday event, she is an average NPC.

She may be a bit lewd, because for her task, she'll ask Yandere-chan to retrieve a bra that she lost. Saki seems very embarrassed about the bra and the story about it might be revealed in a future update.

If Saki hears about Kokona's compensated dating, she will be surprised. She is 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 her comforting 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.

Routine
At 7:05 AM each day, Saki Miyu enters the school grounds, sixth in line on the right, if facing the school gates. She walks to her locker at 7:10 AM. At 7:15 AM, she walks to the plaza, on the left side of the fountain and gossips.

At 8:00 AM, Saki walks into Classroom 3-1 and sit in her desk. She starts her morning classes at 8:30 AM, and leaves to go to lunch at 1:00 PM.

On Monday at 1:00 PM, Saki talks with Kokona about domestic abuse on the rooftop. Yandere-chan can listen in on the conversation, but Saki and Kokona will stop talking if they notice Yandere-chan. During the rest of the week, she gossips with her group during lunch.

Saki walks to class again at 1:30 PM and finishes her afternoon classes at 3:30 PM. From 3:40 PM to 5:30 PM, she eats octopus-shaped hot dogs with Kokona Haruka in the Cooking Club. At 5:35 PM, she walks to her locker and stands there before leaving the the school building at 5:45 PM.

Task

 * Main Article: Tasks

She is the only student who currently has a task, and thus the only friend Yandere-chan can have at the moment.

Saki's task is to find her bra. Her bra has been near The Cherry Tree, against the fence, both before and after the November 15th, 2015 Update. The story behind it might be revealed in a future update. Once the player collects and and brings it back to her, Saki will be very happy and become her friend.

Kokona Haruka
According to her Student Profile, Kokona Haruka is Saki's best friend and closest confidant. Kokona is willing to discuss personal matters with her, such as during the rooftop conversation about domestic abuse on Monday. If Yandere-chan reveals Kokona's compensated dating on the Internet, Saki Miyu will be confused and distraught.

YandereDev said that Saki might comfort Kokona, but there would be a limit to that because Saki could lose reputation as a result of it.

If Kokona becomes a rival, Saki will become her subordinate. Saki will not have a crush on Kokona, as they are just friends.

Trivia

 * Saki was voiced by Chelsea Druce, a voice actress shared with Kokona, during the rooftop conversation.
 * Her name is a reference to the most popular female Japanese names in 2012, the ninth most popular being Saki and tenth most popular being Miyu.
 * When YandereDev was struggling to find hairstyles that he could create by duplicating and changing the size of a ponytail, the last idea that he came up with was "two long twin tails". He made them cyan because they reminded him of Hatsune Miku. Because Saki's design will change, she will not resemble the Vocaloid anymore aside from color.
 * In older versions of the game, Saki Miyu's name was Azu Naka. This placeholder name was inspired by K-ON.
 * Her male counterpart is Sora Sosuke.
 * By opening the debug menu and pressing the M button, Saki Miyu will become brainwashed without needing to kidnap and torture her.
