Kokona wears the default female school uniform unless customized by the player. She has fair skin, light purple eyes, and a very large bust size of 2. Her hair is light purple color and is styled into twin-drills with right-swept bangs and rounded locks that frame her face. As a member of the Drama Club, she wears a red rose accessory in her hair; she also wears a purple friendship bracelet on her right wrist. If the Drama Club is disbanded, she will remove her rose accessory for the rest of the game. If her reputation drops too low, she will remove her bracelet.
As of the February 8th, 2016 Build, Kokona has had her current hairstyle – rounded twin-drills and right-swept bangs. Additionally, from this build until March 18th, 2017, she had dark purple eyes.
From the September 20th, 2016 Build until the August 18th, 2018 Build, Kokona wore purple stockings and purple panties.
As of the January 16th, 2017 Build, Kokona wears a purple friendship bracelet on her right wrist unless her reputation is below -33.
As of the March 18th, 2017 Build, Kokona's eyes are once again light purple.
As of the August 18th, 2018 Build, Kokona has a Drama Club rose accessory in her hair. Her purple stockings, panties, and friendship bracelet were removed.
As of the August 22nd, 2018 Build, Kokona's friendship bracelet has been restored.
From the December 25, 2018 Build to the December 26th, 2018 Build, Kokona had silver-white eyes. This was a bug.
Among the personas currently implemented in the game, she is a Social Butterfly. She will happily pose for a picture if Ayano aims her 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 she witnesses them murder Saki Miyu, or Riku Soma if he is her boyfriend.
According to her former 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 has been proven false as of the June 1st, 2016 Build. Although she does not enjoy it, Kokona only engages in such an activity to try and help her father out of debt.
According to her current Student Profile, Kokona admires Kizana Sunobu, leader of the Drama Club, and joined the club to learn how to be more like her. This annoys Kizana, who doesn't want anyone imitating her unique style.
If she and Ayano ever teamed up to kidnap Musume Ronshaku, Musume would be able to push Kokona to the point of murder if she repeatedly mocked her father's financial situation and her compensated dating.
In one of Druelbozo's streams, he explains that Kokona tries hard to become popular, but she is constantly bullied.
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 Gymnasium and watches Tsuruzo Yamazaki and Tokuko Kitagawa rehearse for an upcoming play with Shozo Kurosawa and Riku Soma.
At 8:00 AM, Kokona 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 and goes to the outside of the Drama Club to eat her lunch at 1:00 PM.
Kokona walks back to class again at 1:30 PM and participates in cleaning time between 3:30 PM and 4:00 PM. She then heads to the Gym and stays there until the end of the day.
If the Drama Club is disbanded, she will socialize with the other former members outside of the club room during periods in which she would normally attend it.
On Monday, at 7:45 AM, Kokona receives a call from a mysterious stranger and runs to the eating area behind the school. She goes to the rooftop from 1:10 PM to 1:20 PM to talk with Saki about what is vaguely hinted to be domestic abuse. After cleaning time she goes to the Cooking Club, makes octopus-shaped hot dogs, and shares them with her friends.
On Wednesday, at 7:45 AM, Kokona goes to the girls' bathroom on the first floor. She 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. This was later removed in the May 22nd Build
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. After cleaning time she makes octopus-shaped hot dogs and leaves them on the table.
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 incorrect. When spoken to, 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. If Kokona's dark secret is bought, Info-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.
- Main Article: Tasks
Kokona has a uniform that is too tight around her chest. She will ask Ayano to get her a new one. To achieve this, she has to buy a clean uniform from the drops menu using 5 panty shots, and then take the uniform to the sewing room and alter it. She will thank her after the new, altered uniform has been given to her.
- 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 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 Ayano to find her bra somewhere at school.
- Main Article: Senpai
Kokona is currently a test rival. 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.
- Main Article: Riku Soma
Kokona's secondary crush is Riku and as of the 22nd of September, 2016 Build, Ayano can matchmake Kokona with him.
- Main article: Kokona's Father
Kokona cares immensely for her father, being concerned for his emotional wellbeing to the point of engaging in compensated dating to try to help him out of debt with loan sharks. It is initially presumed that her father beats her; this is proven untrue with her conversation, and instead, her father comes to her to cry about the debt problems, signifying a close parent-and-child relationship.
The topics towards Kokona are Negative/Neutral/Positive as follows:
- Video games
- Everything else.
- If Senpai is not at school on Wednesday when Kokona goes down to the plaza to eat, she will walk in place.
- In the January 3rd, 2017 Build, when Kokona goes to eat her lunch by the fountain on Wednesday, her event will still play out, even though Senpai has been moved to the rooftop.
- Many fans link Kokona's appearance to Teto Kasane the UTAUloid. However, YandereDev did not intentionally make Kokona look like Teto. It was pure coincidence.
- Her hairstyle is final. 
- Kokona's hairstyle was originally cyan instead of purple, however, YandereDev switched her hair color with Saki due to making Saki have cyan Twintails.
- Her name is a reference to the eleventh and twelfth most popular female Japanese names in 2012, 11th most popular being Kokona, 12th most popular being Haruka.
- The 'koko' in her first name means "here", and 'haru' means "spring". 'Ka' and 'na' are adjective-modifiers, and therefore they do not have any meaning in her name.
- YandereDev used her character to test the original elimination methods every new update, as he has shown in his tutorial videos. When asked about the reason for this, he stated that somebody had to be the guinea pig and she was simply unfortunate enough to be the one picked.
- In older versions of the game, Kokona Haruka's name was Nodo Mana. The placeholder name was inspired by Nodoka Manabe in the anime K-On!.
- YandereDev is not sure where Kokona lives at the moment.
- YandereDev nicknames Kokona as "Everyone's favorite punching bag", referring to how she can be killed in more ways than any other student. The main reason why it was so easy to kill her is because YandereDev needed to test killing methods quickly for the sake of debugging the game.
- Kokona succeeds Victim-chan as the test rival.
- Her male counterpart is Riku Soma.
- Before the June 29th, 2016 Build, Kokona used to arrive on school grounds 7th in line on the left side, at 7:05 AM.
- In the September 18th, 2015 Build, her crush was set to "None" by mistake.
- Kokona makes a small cameo in the Gaming Club by appearing on the racing game, racing against Saki.
- Her cell phone is the same purple color as her hair.
- Pressing "G" on the debug menu will cause her and Ayano to teleport to the rooftop, where the player can push her off or offer help.
- Kokona finds slicked back hair, purple hair, glasses, piercings, and intelligence attractive in a guy.
- As part of the final game, Kokona (being member of the Drama Club) would possibly serve as a tutorial to Ayano on various game mechanics. She would do this by acting out various features, such as performing attacks and dropping items.
- Kokona was the first in the rainbow six to get colored stockings and panties.
- Kokona's hair physics were restored in the August 20th, 2017 Build.
- She is considering a career as an actress.
- YandereDev may consider that Riku is her boyfriend, as she won't be an important character in the final game.
- In YandereDev's video, "The Curious Case of Kokona Haruka", it was said that he was running out of hairstyles for Kokona, so he decided to go for something different; which was twin drills.
- As of the October 17th, Build, she can be seen sitting on a bench in town cuddling with an older man. (However if you freed her father of his debt/killed her, she won't appear)
- As of the October 17th, Build, she appears to have a different hairstyle model in the town.

Oh...you've got it all wrong! My father doesn't do anything to me!
He cries...and talks about his debt problems...
When my mom died last year, my family lost a lot of money...my dad took out a loan so that he could continue to pay for my tuition fees...but...It turns out that he borrowed money from some really shady people...they raise the interest rate by 10% every ten days...and they threaten to get violent with him if he doesn't pay up...
I'm trying to help my dad get out of debt...I'm trying to earn money any way I can, but...the only ways to make money fast are...gross...
Um...I think it's called...Ronshaku Loans.
What? No! Please don't get involved. I doubt there's anything you could do about it...
I appreciate your concern...but I don't think there's anything else to be said...thanks for letting me talk about my problems...
— Kokona's conversation with Ayano at the rooftop.
|“|| My dad just got a phone call...he says his debts have been wiped clean!|
Did...you do this?
What did you do?!
That's...kind of scary...but, I can't remember the last time I saw my dad this happy!
I don't know what you did...and I'm...afraid to ask...but you saved my dad! Thank you so much!
Words can't express how grateful I am! If there's anything you need me to do for you, just say the word!
What is it?
I'll be there! And, one last time...thank you!
— Kokona's text conversation with Ayano.
|“|| You have a nice place, Yan-chan!|
Where are your parents?
So, you take care of yourself? That must be hard.
I want to thank you again for helping my dad. I won't ask what you did. I'm sure it's something you wouldn't want to talk about...But I hope you gave him what he deserved! Loan sharks are awful people...I did a bunch of stupid things while I was trying to make money, but my biggest regret was getting Saki involved. I never told her about my dad's debt, but I did tell her that I needed money fast. She tried to help me out by selling her underwear to some boys outside of school. In the end she couldn't go through with it, so instead of selling her bra, she threw it over the school wall! I wonder if she ever found it...That must have been so embarrassing for her...I feel so bad about it..but now it's all in the past. You saved my dad, and now I can finally stop spending my time trying to make money in gross ways! Oh! I just realised I've been rambling this entire time. You said you had something important to tell me, right?
...oh...you know about that...?...what did you want to say about him...?
...I...have...really strong feelings for that boy...I don't want to lose him...but...I could never take someone away from you, after everything you've done for me...okay...I'll stay away from him.
...but...you'd better take really good care of him...okay?
