She is a woman of average height with long blonde hair and yellowish/brown concentrically-ringed eyes.
She is one of the few characters who is not initially weirded out by Machio Naruzo flexing and tearing his clothes, being more interested in his advice. Like Kure Yakusha and Tachibana Satomi, she is angered by quips about her age.
- Tachibana Satomi: Rumika is good friends with Satomi. Both share an interest in cosplay and getting married.
- Kure Yakusha: Aina has a good relationship with Kure-sensei, with them both being teachers. She respects Kure-sensei's physical abilities.
