Kokona Haruka

Kokona Haruka is one of the female students and the current test rival that attends Akademi High School.

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

Before the February 8th, 2016 Build, she had purple colored hair worn in two drill pigtails. Her eyes were light purple as well.

As of the February 8th, 2016 Build, she has light purple spiky bangs which sweep to the right of her face and twindrills. She has dark purple eyes, fair skin and a very large bust size, set at 2.

As of the September 22nd, 2016 build, Kokona wears purple stockings and panties.

As of the January 16th, 2017 Build, Kokona wears a purple friendship bracelet on her right wrist.

Personality
Among the personas currently implemented in the game, she 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.

According to her Student Profile, Kokona may be participating in compensated dating (also known as Enjo kōsai) and may be a victim of domestic abuse, though the latter is proven false as of the June 1st Build. Although she does not enjoy it, Kokona only engages in such an activity to try and help her father out of debt.

In one of Druelbozo's streams, he explains that Kokona tries hard to become popular, but she is constantly bullied.

Routine
At 7:04 AM, Kokona enters the school grounds. She walks to her locker at 7:06 AM and changes from her outdoor shoes to her indoor shoes. At 7:15 AM, she walks into the plaza, to the left side of the fountain, and gossips with Yui Rio, Yuna Hina, Koharu Hinata, Mei Mio, Saki Miyu, and Musume Ronshaku. On Monday, at 7:45 AM, Kokona receives a call from a mysterious stranger and runs to the doorway in front of the lockers furthest to the right when facing the school. On Wednesday, at 7:30 AM, Kokona goes to the girls' bathroom on the first floor. On Thursday, at 7:15 AM, she goes to the shower room to take a shower and leaves her phone inside her locker, which the player can steal.

At 8:00 AM, Kokona walks into Classroom 3-2 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 Saki about what is vaguely hinted to be domestic abuse. On Wednesday, Kokona stays in the classroom until 1:03, when she walks down to the plaza with her lunch. Once she arrives at 1:07, she places her lunch down on a bench and goes to hide behind a tree to admire Senpai. On all other days, she goes to the cafeteria to gossip.

Kokona walks back to class again at 1:30 PM and finishes her afternoon classes at 3:30 PM. She then heads to the Cooking Club and stays there until 5:00 PM. On Monday and Thursday, she makes octopus-shaped hot dogs and shares them with the other members. On all other days, she sits at the table like the other members. Afterwards, Kokona heads to her locker and changes from her indoor shoes to her outdoor shoes, then she lingers there until 5:15 PM, when she walks home.

Background
When Kokona was younger, she was a normal cute baby with the potential to become anything she wanted to, just like any other.

It is assumed in a conversation between her and Saki Miyu on the rooftop that she has been abused by her drunk father after her mother's death. This is actually incorrect. When spoken to more, Kokona will talk about how her father comes to her to cry about his debt problems. Her family is very broke due to a loan he took out to pay for Kokona's school tuition, accidentally becoming in debt with a group of loan sharks, called Ronshaku Loans.

Kokona Haruka is also involved in compensated dating with a person who she has seen at least once in Shisuta Town. He might have offered her a large sum of money to meet him. If Kokona's dark secret is bought, Yandere-chan will receive video footage of Kokona selling used panties to a boy from another school that can be used as blackmail. Kokona does this to pay for her father's debts.

Task

 * Main Article: Tasks

Kokona will have a uniform that is too tight around the chest. She will ask the player to get her a new one. To achieve this, the player has to buy a clean uniform from the drops menu, and then take the uniform to the sewing room and alter it. She will thank the player after the new, altered uniform has been given.

Saki Miyu

 * Main Article: Saki Miyu

Kokona is seemingly good friends with Saki, and almost opens up to her about her father's debt problems. According to Saki's Student Profile, Kokona is willing to tell Saki about personal matters, but not too much.

However, if Saki learns about Kokona's compensated dating, she will be distraught and won't do anything to help Kokona out. In the full game, Saki might have comforting animations for Kokona, but will avoid her if it really gets too bad.

Saki Miyu will not be Kokona's senpai, as they are just friends.

It is revealed that Kokona had Saki involved in her plans for her father to get out of debt, though regrets having Saki help her, as Saki planned to sell her underpants to boys from other schools, but was too embarrassed to carry it out. This sets up Saki's task for Yandere-chan to find her bra somewhere at school.

Senpai

 * Main Article: Senpai

Since she is a test rival, she has a crush on him. Kokona calls him "Senpai", even though they're in the same class. She might also be moved to either Class 2-1 or Class 2-2 so that she can still call her crush "Senpai". Currently, the only event that shows her feelings is her Wednesday speech, where she hides behind the tree and speaks while staring at Senpai. This event can be used as an opportunity to poison Kokona's bento.

Riku Soma

 * Main Article: Riku Soma

When the November 15th, 2015 Build came out, YandereDev stated that Kokona's second crush is one of the students who already attends school. As of the 22nd of September, 2016 Build, Yandere-chan can matchmake Kokona with her suitor, Riku Soma.
