Among the personas currently implemented in the game, she is a Social Butterfly. She will happily pose for a picture if Ayano Aishi 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.
If she has her phone out when seeing a corpse or witnessing a murder, she will switch to the Phone Addict persona.
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, 2016 Build. Although she does not enjoy it, Kokona only engages in such an activity to try and help her father out of debt.
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.
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 Drama Club and stays there until 5:00 PM.
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 7:30 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.
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 shares them with the other members.
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, Ayano 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 the 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.
- 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.
As of the September 15th, 2017 Build, Saki will attack Ayano if she kills Kokona in front of her.
- Main Article: Senpai
Since she is a test rival, she has a crush on him. Kokona calls him "Senpai". She might also be moved to either Class 2-1 or Class 2-2 . 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.

- 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 hairstyle was originally cyan instead of purple, however, YandereDev switched her hair color with Saki due of making Saki have cyan Twintails.
- Pressing K in Ayano's bedroom will cause her to appear inside the basement.
- 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 uses her character to test the new 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 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 is so easy to kill her is because YandereDev needs 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.

- Kokona finds slicked back hair, purple hair, glasses, piercings, and intelligence attractive in a guy.

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?
