Akane is a cheerful and gentle girl. She's good at taking care of others, having used to taking care of her two younger brothers because their parents were rarely at home, and at the dorm she took care of her roommate Motomiya Matsuri. A hard worker who at the same time tries to balance studying and doing household chores.
Apparently she and Terase Yuno are the ones with the most common sense in their unit, as she and Yuno frequently throw retorts at her friends' antics, although the later more often got carried away with the flow of the conversation.
Akane is not familiar with Earth customs such the Hina Matsuri (Girls' Day), which implies that she was probably born and raised on the Moon.
She came from a family of five, consisting of Akane herself, her parents, and two younger brothers. Both of her parents are skilled researchers, and they often had to stay over at their workplace, which possibly caused Akane's grandmother to take care of her when she was young and led her to be a grandma's girl. Also, due to her parents' lack of ability in managing a proper lifestyle, managing the house and her two brothers ended up becoming her responsibility.
When Akane got to live in the school dorm, she was assigned to share a room with Motomiya Matsuri. Because Matsuri likes doing experiments and researches, just like Akane's parents, Akane ended up feeling that she couldn't help but caring for her.
