Also known as: Kokona_Haruka
Kokona Haruka is a character from the sandbox game Yandere Simulator. Recognized for her Large Breasts and purple Twin Drills, she is considered a rival of Yandere-chan due her crush on Senpai.
Despite this characters appearance being similar to the popular UTAU, Kasane Teto, this was unintentional as the original base model of the character was simply a 3D model of Teto.
