I want to see more characters from unknown shows shine and Airi is no exception.

Those Who Hunt Elves is a very underrated isekai from way back in the 90s featuring a misfit cast of a martial artist, an actress, a military obsessed school girl and an army tank that later gets possessed by a cat spirit, while much of the story is slapstick in an absurd environment, Airi stands out as being an exceptional character.
Master of disguise, can read any scenario, can emote on command and brings a presence that the other characters fail to achieve if they ever went solo, in fact it was Airi that first unveilved one of the anime's biggest plot reveals, she reminds me of the performers of the Takarazuka Revue even though her bio suggests mixed American and Japanese, also at aged 24 is the obvious adult of the group.
Way more capable than her era would suggest.
