Shaula has dark green eyes and long blackish brown hair which she ties together in what she refers to as a scorpion tail. She is tall, has a model physique along with a large chest, and only wears a black bikini, hot pants, and a cloak.
Shaula is described to be like a girl at the bottom of a girls caste who runs errands for others. She is absolutely loyal to Flugel, however she tends to be thoughtless so she is unfit for mental work. Also, she is unable to tell people apart and therefore refers to Subaru as her teacher based on smell alone as he apparently smells the same as Flugel.
Immense Power: Shaula is mentioned to be strong enough to easily deal with Sin Archbishops and even force Reid Astrea to use both hands while in combat once every ten times.
Hell's Snipe (ヘルズ・スナイプ Heruzu Sunaipu): Shaula is able to connect her needles and her target together with mana and release it as if it's gravitating toward them. It is fast, powerful, and is able to be fired rapidly.
