Kokona Haruka is one of the female students that attends Akademi High School. She was a test rival for older debug builds of Yandere Simulator.


Kokona has purple hair that is styled in twin drills. Three strands of naughty hair stick out on either sides of her head. Her eyes match her hair; a vibrant purple. She also wears a small rose in her hair if the Drama club is active. She wears the default uniform unless customized by the player. She has a very large bust size of 2. She wears a purple friendship bracelet on her right wrist.

In builds before August 18, 2018, Kokona used to wear purple thigh-high stockings. Now, she wears the plain white knee-highs.

Kokona can be seen in her casual outfit when the player visits the street: A long-sleeved lilac top with a white doll-collar and a white, ruffled skirt. She also wears lilac heels and white knee high socks.


Kokona is a Social Butterfly. She will strike a cute pose if a camera is pointed at her. If she witnesses murder or discoverse a corpse, she will run to a heavily populated area and call the police. However, if Saki Miyu is killed in front of her, she will attack the player with the strength of a Martial Arts Master.

According to her profile, she looks up to Kizana Sunobu, the leader of the Drama Club, and joined so she could be more like her.


Saki Miyu

Kokona and Saki are best friends. They both wear friendship bracelets. If Saki is dead, or Kokona is being bullied, she will no longer wear the bracelet. The same goes for Saki.

In Kokona and Saki's rooftop conversation, it is revealed that Kokona may be "abused" by her drunk father. Saki worries for her, showing that she's a caring friend.

In the future, Saki may avoid Kokona if she finds out about her compensated dating. Saki has been involved in Kokona's plan to free her father from debt by selling used underwear. In the end, Saki couldn't go through with it and threw her bra over the school wall.

Riku Soma

He is Kokona's male counterpart and secondary crush. He has a crush on her as well. From the September 22nd, 2016 build, it was possible to matchmake the two. This was removed in preparation for Osana.

Kizana Sunobu

Kokona admires Kizana, and joined the Drama Club to be more like her. Kizana dislikes her, as she doesn't want anyone imitating her unique style.

Musume Ronshaku

Musume is the daughter of the loan shark who is exploiting Kokona's father. Although the two don't have much of a relationship, it was possible to kidnap Musume and send the video to her father. Mr. Ronshaku is then blackmailed into freeing all his clients from debt.
