Nei Ookawamura is a member of the 7th Unit, assigned as rear guard specialist in scout ability. She is a young girl with bright white skin, long pink hair with a headband, and blue eyes. In important meetings, She is seen wearing a uniform of Anti demon corp along with a red belt and long skirt. In her break and emergency situation, she is seen wearing casual clothes in operation. She is a kind, hard-working girl that easily gets along with the 7th unit, including Yuuki in their first meeting. Despite she is young and still elementary, she can easily get along with Yuuki on another level. She appears to be easily flustered as she becomes embarrassed after kissing Yuuki on the cheek as the price of using Kyouk's power.
