Squall has long blonde hair and a pair of reddish eyes. She has a voluptuous body with a large bust that been described as very attractive by both Ran and Ichika.
Squall shares a homosexual relationship with Autumn but it is unknown if she is really into the relationship or if she is just using Autumn. She offen displays herself as a mature, level-headed lady in front of other, be they friend (her squad) or other people (enemy or not). While she can be very ruthless when she want to be, she did order M not to kill the soldiers at the American base. Suggesting that either she doesn't like needless overdoing thing when it's unnecessary or perhaps she has some other reason.
During the CannonBall Fast, Squall accidentally bumps into Ran Gotanda. She is later shown commenting on M's abilities of holding off all six personal IS users effortlessly, before getting into a skirmish with Tatenashi Sarashiki. She is shown to be skilled enough to hold off Tatenashi with partial deployment and block all her bullets with a yellow cocoon-like shield. She confidently tells Tatenashi that the Mysterious Lady would not break through her IS but chooses to escape from the Academy instead.
Squall: "Hey, M. Whether you're Orimura Madoka or not, I don't really care, but please maintain your identity as M while being a member of Phantom Task."
Madoka: "...I intend to do so until I settle the score." Squall: "Settle the score...with Orimura Ichika?"
Madoka: "Humph...he's not a threat at all. I can kill him whenever I want to."
Squall: "So that means, with Orimura Chifuyu...right? - Orimura Chifuyu, is it? She doesn't have an IS, so I don't think she's much of a threat."
Madoka: "Don't you ever humiliate her...Someone like you will never be a match for nee-san..."
Squall: "Okay okay, I got it. So M, don't throw the knife. You'll damage the wallpaper."'Madoka: "Humph..."
Squall: "I'll go sleep for a while. Ah, M? There's still some time until the next mission, so please control yourself a bit." Madoka: "Got it." Squall: "I like honest kids. Bye then, M." - Squall to Madoka
