Odessa Casella is Kamiko's 3rd Yandere Simulator OC


Odessa has straight salmon-pink color hair with a blue strand on the left side of her hair. She wears her hair in a ponytail held by black ribbon. Just like her sister Chiyo Casella she has Heterochromia. Her left eye is red and her right eye is light grey. Odessa has a pale skin tone. She has a freckle on the bottom right side of her mouth. Despite her biological gender being female, she wears the male uniform as she prefers to wear male clothing. To avoid being caught by school regulations, Odessa tucks her long hair into her uniform and she wears a breast binder to hide her breasts. Odessa also has black glasses. Since she's in the Gaming club, she will wear a D-pad hair clip. 


Odessa looks the same however she would wear the 3rd years male uniform.


Odessa is known to be very geeky, and asocial(unless she's with her friends). Her hobbies are known to be gaming and writing stories. Odessa usually acts emotionless towards others(unless something extreme happens), however she seems to be more cheerful when she's with her friends. Odessa usually tries to maintain a calm or neutral emotion when she's talking with other people. She also shows a big obsession to video games. She will go fan girl crazy if someone mentions a certain video game in front of her. If something happens to one of her games or consoles she can throw a temper that would last from a minute to a month depending on what happens and what object has gotten affected. She shows a huge dislike to wearing skirts or dresses. She would most likely wear a suit or a tuxedo if she had to wear something formal.
