Sexykam Hey senpai! This OC is owned by this idiot right here. Please ask "it" for permission before you use or make any changes to this OC! Otherwise it'll become triggered and...yeah Edgykam

Otsune Chisu (Also known as, Odessa Casella, outside of the Yandere Simulator universe) is a multi-fandom OC made by Kamiko.

Theme songs


Otsune has a fair skin tone. They have neck-length, dark-red hair that they wear down and have their bangs parted to their right. Just like their sisters, they have amber eyes. Due to being near-sighted, they wear black rimmed glasses. Since they prefer to wear the male uniform, they wear a chest binder to hide their breasts in order to not be caught wearing a uniform unsuited for their biological gender.  


Otsune looks the same however they wear the 3rd years male uniform.


Otsune is slightly arrogant, but, they're not very. They used to be very snobby to the point that they became a bully when they were a child, most likely because their father used to spoil them too much. Luckily, they matured way more as they grew up to become a teenager. Otsune will usually have no problem saying what's really on their mind and their opinions, which, makes some people think that they're a jerk. They are also very confident and prefer to do most tasks themselves, even if they have no idea what they're doing.

Unlike their past self, who was always attention hungry, they tend to stay away from crowds as they rather be alone, playing video games. However, Otsune isn't entirely anti-social, as they like befriending people who share common interests with them and love to hang out with friends.

They show a huge obsession towards video games and video game characters. Otsune will always keep a 3DS with them and will freak out if they lose it or if something bad happens to it. Otsune will also play games on their phone. They're excellent at playing racing, fighting, and platform games.  They also have a body pillow of a female video game character, which they claim, is their "main waifu".

Since Otsune doesn't socialize with a ton of people, it's sometimes hard for them to empathize with people, especially with people who they don't know very well. Otsune is also very oblivious to tell when someone's romantically interested in them.


Not many student's know Otsune is biologically a female. Only they're closest friends and some people that have a full understanding of the difference between female and male anatomy know this. If the player splashes Otsune with water, blood, or gasoline and follows them to the girls shower room(They will only go inside if there's no one currently in there, so the player must time it well) and takes a picture of them undressing without them noticing. Their student information box will have more information added to it. This is also a perfect opportunity to snitch on them by telling the counselor about Otsune wearing the wrong uniform. If the player does that Otsune will come to school wearing a female uniform(and also a very irritated expression). If the player gets caught by Otsune, they wont get a reputation penalty, Otsune will only beg the player to not tell anyone, this is also a perfect chance to blackmail them. If the player tells the counselor about Otsune's clothing, even if they do get caught, Otsune will refuse to talk to the player as they now dislike them. To earn back their respect, the player might have to do a lot of favors for them.

Reaction to Suspicious Actions

Bloody Clothing- Otsune will look at you for a sec. but they will ignore it unless a murder took place. If a murder did take place Otsune will take a picture of you while hiding to avoid getting spotted, and send it to the police.

Suspicious Weapons- Otsune will question you if a murder didn't happen. If you're in the drama club, Otsune will assume it's just a prop. If a murder happened Otsune will take a picture of you if you show any other suspicious behavior(bloody clothes, looking insane, blood on weapon, etc.) If you don't, Otsune will try to follow you around while hiding from you for at least 20 min. to see if you'll express any odd behavior. They'll eventually give up after 20 min. if you don't express any other odd behavior.

Evil Laughing- Otsune will just give you a weird look and ask you what are you doing. If you're in the drama club, Otsune will just assume you're practicing a line. If a murder happened and you're bloody, Otsune will take a picture of you and send it to the police.

Medium or Low Sanity

Blood on Ground- They'll assume it's just some weird stain if no murders happened. If a murder happened, they'll take a picture and send it to the police.

Reaction to Murder 

Otsune has the Phone-Addict/Traitor persona.

Since Otsune has their phone almost out all the time, mostly used for playing video games. It's pretty easy for them to take pictures of suspicious behavior and send it to the police while running out of the school. If Otsune is near you where you can clearly see them, Otsune will react upon the Traitor persona and will take a picture of you and run away while you're back is turned.

Acquaintances- React upon the Phone-Addict/Traitor persona.

Friends- Try to apprehend you.

Sister- Try to apprehend you.

Enemies- React upon the Phone-Addict/Traitor persona.

~If you want my OC to have any sort of relationship with Otsune just either post a comment on this page or post a comment here:

Seishirō Morita- Friends. Otsune doesn't seem to enjoy hearing his loud music, mostly because they're trying to concentrate on they're video games. They're on good terms though.

Zeon Wakiya - Best Friends and classmates. They both known each other since there first year in Akademi. They started to hang out on their late 2nd year. They sometimes play video games together(and Otsune mostly beats him, because Otsune's way more experienced than him), and they're really close. Otsune's completely oblivious to his true feelings for them but they're willing to date him if Zeon confesses.

Chiyo Chishu- Their younger sister, Otsune used to bully her when both of them were about 2-5 years old. They used to destroy her toys, mess up her hair, scream at her, and always put the blame on her when something's wrong. This was because Otsune used to be spoiled a lot as a child and wanted to have all of their parents attention. Luckily, none of these things happen anymore as their obviously more mature now. Both of them currently have a pretty stable relationship. Chiyo also trusts them the most out of their siblings.
