Meniko Hamukai 食飼命日子

A student at National University of Kyokuritsu Manase. Appears in "Shinobu Mastered/Mustard".

The first friend that Koyomi made after entering the university, who is not involved in any mysterious phenomena. She's not a mystery fanatic, but she likes to solve codes, so she takes a course in cryptology, and that's how they became friends.

She is a slow learner and is not good at changing her plans once she has made them, so she often sits idly in class when classes are cancelled. For some reason, she thinks very highly of Koyomi.

She's NISIOISIN's favorite character from Monogatari Series.
