[3] Inoue's vocal roles are usually female characters characterized as dignified, reserved, beautiful, kind, regal, mature or domestic.

Kasumi Tendo is an older sister who has taken over domestic duties after the death of her mother, and who acts as a counterbalance to the more rambunctious members of her family.

She also plays Rune Venus in El-Hazard, a princess and leader of her country; as well as Kazami Mizuho in Please Teacher!, a sensible, strong-hearted alien agent in charge of observing humanity that ends up falling in love with an earthling.

When she thinks of maid characters, she always tend to imagine them as a lighthearted one, but Kirumi is definitely the type of an amazing perfectionist whose only cred is "selfless devotion."

She occasionally takes on roles which are more sultry, such as Corvette in Idol Project, a curvaceous dancer who flirts quite intensely with Mimu, the young heroine.

She is referred to as "Onee-chan" ("big sister" in Japanese) and stayed with the title on her official site and a few albums because of her role as Kasumi Tendo in Ranma ½; this is confirmed in her online profile.
