一之瀬 葉子

Likes: anime, reading, peanuts
Skill: slash fiction
Role: researcher who just happens to pass by

A woman who is a former researcher at Hokuren Institute of Physical and Chemical Research where she worked under Yuriy, the deputy director. She is a talented woman who specializes in neuroscience and is currently working as an assistant professor at the university that Reiji attends. At a glance she seems like a levelheaded adult woman, but on the inside she obsesses and gets excited over passionate relationships between men both real and fictional, so she has some quite "rotten" interests.
