Nanami has the least amount of experience compared to the other members, and she did not have much knowledge of anime culture. Originally she was not interested in anime, but over time she was influenced by the other members little by little.

At first, Nanami did not enjoy voice acting lessons because she was unfamiliar with anime and was not confident in her acting. As her character Hisami Nanami began to develop, she started to enjoy voice acting and began to want to work as an independent voice actress. Since vocal lessons were anime songs as well, she had to work harder since she was unfamiliar with​ the anime songs.

Her favorite voice actress is Rie Kugimiya, since her work in Toradora! was the first time that anime had made her cry. She learned many things from voice acting from Rie Kugimiya's role as Aisaka Taiga.

__Non-anime roles:__
- Yulha - Goddess of Victory: Nikke (VG)
- Kirara Yozakura - Blue Archive (VG)
