== Personality==
As a male, Mahiro used to be a shut-in that past and has a love for manga with especially the topics of sex slavery and would spent almost the entire day playing video game at home for over 2 years straight. As younger child, he spent more time with his younger sister, where he would often give her various gift to her as a reward for her good grades at school. Mahiro would give Mihari a hair clip, stickers and even bring her to amusement parks during their free times. However as Mahiro got older, he would spent more in his room playing games and reading manga, due to feeling less superior to his sister as she was able to achieve many notable things. In additions to his inferiority, he was also under the struggles of adolescent of pressure. Upon being turned into a girl as he woke up, Mahiro did not appeared to be mad neither irritated to his sister even after learning that she was responsible for the change of his gender. Mahiro appeared to be more shocked and showed curiosity of checking his new body’s private parts. When Mihari forces “her” to go outside she would get nervous and scared mainly due to the time he spent after so long as well as due to now of being a minor again. In addition she also displayed a fear for large crowds but would eventually get used to with her time that she spend in middle school alongside her friends.
As the series progresses, they would basically switch roles of siblings, where Mihari get more of the older sister figure and Mahiro the younger sister figure. For example Mihari would teach her how to brush her hair, buying new clothes for her or cook for her. However that is not always the case, as Mahiro did cooked for in return while she was sick, resulting in Mihari to get emotional and break in tear. Mahiro’s personality would also lose his boyish personality and develop more female habits. For example she was shown to sit like a girl while playing games. She would start display the status of a lovable younger sister that always needs her older sister around. Mahiro would often quickly hide behind his sister whenever they meets strangers despite older. Nevertheless Mahiro would still have boy feelings inside him where he would get excited whenever he enters the female bathrooms or change rooms and enjoyed how Asahi hugged him, drowning his face into her chest. Furthermore he has also been shown numerous times to get nervous flustered whenever a girl (especially with big sized chest) gets near or when one is undressing as show during his time in the changing room for girls despite being a female now. She would look towards his friends who are flat chests to cool him down as Mahiro is aware that he would be looking weird in doing so. To close off, she/he decides to balance his habits and status as both a male and female by trying to losing his masculinity so that he could fit alongside his friends as a female but still does possess the desire to fully become a female.
