ییوریکا کوچیکازای

Kakeru and Najimi's classmate who claims to be Najimi's lover.

She's always having fights with Kakeru and Yell as her rival for Najimi. She's also a self-proclaimed witch and she often uses cards to throw at Kakeru (which, from the back, look like tarot cards but are normal poker cards).

In some instances she shows mysterious powers. Her birthday is on Halloween, which could relate to the reason she believes she is a witch. Her nickname is Yuriri.
