Princess Vanilla is from the "Hime to Boin" PC dating game, and it is in Japanese. Boin translates to 'big breasted' in English, and Hime translates to "princess" in English.
Vanilla is the Princess of Mordivale and is 23 years old. She comes off as a sweet and somewhat sensitive woman, and due to being sort-of sheltered from the outside world because of always being inside of her castle, she can be very shy around people as well, especially the men. Obviously, Vanilla is easily noticeable by her large breasts, which she is deeply ashamed and embarrassed of, for she always wears different layers of clothing to hide them.
