I'm Chisato Ai, Not Chihaya Anon

On a night when the moon shone unusually bright, Chihaya Anon met someone in her yard who looked exactly like her: Chihaya Ai. "Will you become my partner?" Chihaya Ai asked Chihaya Anon that night. At that moment, the original fate changed. The girls who held the Memory Sticks would wander through danger, trapped in an eternity of doll-like lives. Chihaya Ai was drawn into it as a bridge between them. "So this is why you started becoming W with other people?" Chihaya Anon said through gritted teeth, gripping Chihaya Ai's chin.
