Izumi Shimomura

下村泉, Yoko Tainaka
Izumi Shimomura is an Ajin. Her name is taken from her birth fathers last name Shimomura and her mothers maiden name Izumi. Her former name was Yoko Tainaka . Izumi is a rather quiet and reserved individual talking mainly when informing Tosaki about something. Her answers are usually short and to the point. Even though she is an Ajin she chose to live between humans in secret and doesnt seem to be consumed completely by resentment towards humans despite her background. She seems to be quite intelligent and understanding both towards Tosaki and when interrogating Nagai Keis younger sister Eriko. However despite her initial stoic appearance she can get embarrassed easily for example when she said too much to Eriko and when Tosaki commented on her casual clothes.
