I never liked Ayane XD but it is true tho, she is the resident bitch of DOA, just like how Kasumi is the resident good girl
Ayane is not a bitch! O_O She's a sweetheart <3! See: http://pre00.deviantart.net/d30a/th/pre/f/2015/307/e/a/ayane_3ds_render_41_by_x2gon-d9fe23y.png
Ayane helped to save mankind against destruction many times, she works behind the curtain, but she is a hero.
Ayane: "Oh... huh. Saving the world. Entertainment concept to say the least. But, recall telling @KasumiLover69 over69 to give me a massage. Kasumi is letting him get away with too much, so I figure I put him in check."
