Chitose Azuma

Chitose Azuma is Mihari Oyama's faculty advisor at the university she attends, as well as the half-sister of Nayuta Tenkawa. According to Mihari, she was responsible for perfecting the drug that Mihari developed to turn her brother Mahiro Oyama into a middle-school aged girl. She has since been using Nayuta to keep secret tabs on Mahiro to fulfill an unknown agenda. Chitose is a tall adult woman with a slender frame. She has messy shoulder-length blonde hair that covers her ears with bangs. She has brown eyes and wears brown square-lens glasses with a rounded edge. She wears a black shirt and a white lab coat over it, and like Mihari is seen always wearing this lab coat, even during casual situations. Chitose is dedicated to her research studies while exhibiting a playful side during social situations. Chitose is fully dedicated when working, and it is shown that she consumes massive amounts of energy drinks in order to power through her work. Despite this, she is shown to have a severe playful side as she like to sneak up on others and surprise them for her own amusement, as well as print her own special kinds of stickers that she gives out to people who impress her. She is also shown to be very caring as she takes care of Nayuta and they share a close relationship. Although she helped Mihari perfect the feminization drug, she did not do it out of the kindness in her heart. She is in actuality working to fulfill an unknown agenda that doesn't involve Mihari. She is shown to be very interested in Mahiro, and will do anything to fulfill her plans, even if it means working behind Mihari's back or using Nayuta to help her. She is very eagar to do this, as she was the one who dummied up Mahiro's identification documents so she could be enrolled at Yotsuba University Affiliated Junior High School.
