|Additional Info|| Founder and President of the Occult Club.|
Seems to have absolutely no interest in anything that is not paranormal.
Stalks the Basu sisters daily in a futile search for evidence that they are supernatural beings.
Oka Ruto is the fourth rival of Yandere Simulator and is the president of the Occult Club.
Oka has messy dark blue hair. Her eyes are light purple. There is a shadow on the top half of her face. She wears the default uniform, unless customized, with spider web stockings and arm warmers along with black panties, and a spider choker.
Oka is a Coward. If a camera is pointed at her, she will hide her face. If she witnesses murder, she will beg the player to spare her in exchange for her silence. If she is spared, she will run home, but will not call the police.
She has a crush on him.
Yandere-chan and Oka are rivals in the game.
Sakyu Basu and Inkyu Basu
Oka stalks the two in the morning, as she is certain that the two are of the supernatural kind. However, if they are dead or "missing", she will stand in the Occult Club instead. Though she has no proof, she believes that Sakyu is a succubus, and Inkyu is a vampire.
In the future, the player will be able to matchmake Oka with her suitor.

- Oka is described by YandereDev as a mix between the Hex Maniac from Pokémon X & Y, Tharja from Fire Emblem: Awakening, and Tomoko Kuroki from WataMote.
- YandereDev finds Oka's appearance to be 'cute'.
