Blu-rayko

Blu-rayko is a computer virus in the form of a girl who lives in a "cursed" Blu-ray disk. Her name is a blend of Burū-rei "Blu-ray", Yūrei "Ghost" and "Reiko", a female Japanese name. Blu-rayko (Blu-wraith) has short light blue hair and dark reddish eyes. She has "wings" that are much like angels wings, and bandages covering a good portion of her body (almost completely when she first appears), including her right eye. She walks in a very "ghost-like" manner.

She appears to be obsessed with her kotatsu, and constantly worries about forgetting to turn it off. Because of her past, she is extremely depressed, to the point where all of the channels on the TV turns blue.
