Накаджіма Норіко

She is the sweet, cute, and possibly most "normal" girl in class 5-3 compared to some of her classmates. Unlike the others, Noriko never tries to look for trouble, but trouble constantly does seem to find her. Originally a "background character" early on (mostly found alongside her best friend Shizuka), "Noro-chan" slowly becomes one of the more prominent members of the class and a consistent target for spiritual activity.

Miki in particular has a beef against her: With her cute face, shoulder-length pink hair and the second-largest bust in the class, the buxom blonde always gets upset whenever Noriko steals the spotlight away from her (consistently saying Noro-chan no kuse ni!!, or "That Noro-chan!") While she does seem docile and quiet, Noriko does occasionally unleash a wilder and more playful side (but it takes certain yōkai phenomenon to do so). She's also known as a bookworm and a rather clever tactician; once she was the key to resolving a very creepy case that involved the ghost of the school library and a series of kidnappings related to the ghost's favorite book, which incidentally was the same as Noriko's.
