Arai Miu

A jinyou living in Kamizawa, and a student council member of the academy there. She only recently arrived into Kamizawa and started living together with her grandmother who owns the local public bathhouse. Due to Anegawa Sakura's continuous nosiness they became best friends before Miya realized it.
Originating from a youkai ancestor called Kawaakago (an infant monster that lurks near rivers and drowns people), she got an ability which makes it possible to use specific objects as relay points. For example she can connect to other cellphones by using a destroyed cellphone as the relay point.
A timid, shy person, who during emergency can change into a splendidly courageous individual. Normally she's so diffident that she has trouble speaking with others, so she often resorts to "speak" via her stuffed toy, as by using it as her mouthpiece she can talk more or less fluently.
She has taken a liking of Uesugi Keijirou, but it's rather difficult for her to "break the ice".
