Giffany

Giffany has fair skin and long, straight, fluffy pink hair with a yellow highlight. She wears a large pink, blue, and yellow hair bow that resembles a computer cable. Her reddish-pink eyes can widen and sparkle when complimented. She wears a white sailor school uniform with blue trim and a pink bow. The collar of her shirt matches the color of her hair bow. She also wears a short, pleated blue skirt and white stockings with two pink stripes.

At first, Giffany appears to be a friendly, innocent, passive schoolgirl with little capacity for criminal intent. However, her extreme obsession quickly reveals this image to be a ruse. She will do anything to keep the object of her affections with her, no matter what, and at the forefront of his thoughts. When the "object's" girlfriend perceives potential competition, Giffany will use a variety of tactics to eliminate her. While her initial methods of scolding and manipulation are relatively tame, she will quickly descend into a murderous rage if the perceived problem persists.
In short, a jealous Yandere.

Giffany is a sentient computer game. She can control machinery and navigate power lines. Giffany can also upload a person's mind into a digital world. However, she cannot exist without the game disc.
By the way, Giffany's dad is an octopus man.
