Angel Sanctuary, Volume 1 Book

When Sara's classmate, Ruri, received a computer disk from a strange man, Setsuna shows up to whisk her away from him. After lecturing Ruri about talking to weirdos, Setsuna comments she's much cuter without glasses, which she dropped in the confusion. Unfortunately, neither of them have been watching the news which reports of mysterious deaths occurring in connection with the CD-ROM "Digital Angels." The disk Ruri received is this same "Digital Angels" disk, and without knowing the danger, Setsuna lets her keep it. As soon as Ruri uses the program, her personality starts to change, and strange things begin to happen as Evils and angels seek the Setsunas's soul for their own mysterious motives....
