Cirucci Thunderwitch dresses akin to the gothic lolita style of Japanese fashion. Her outfit consists of a frilly dress, large poofy sleeves that cut off at her shoulder, short purple-colored hair, teardrop markings on each cheek, and knee-high boots. Cirucci has wings on her back, but it is unclear if they are part of her outfit or something else. The remains of her hollow mask are positioned in her hair right above the left side of her forehead and resemble a spiked hairpin. Despite her rather odd appearance, she has no qualms about pointing out when others have similar habits, as she does to Uryū Ishida. She also gets quite bothered if an enemy attacks her while she is talking. Cirucci's zanpakutō is named Golondrina (車輪鉄燕（ゴロンドリーナ）, Gorondorīna?, Spanish for "swallow," Japanese for "car-wheel iron swallow") and is released with the phrase "rip off" (掻っ切れ, kakkire?). In its unreleased state, it takes the form of a whip with a chakram looped into it that is capable of deflecting incoming projectiles in addition to its function as a standard whip. When she releases it, Cirucci sprouts large wings with ten moon-shaped blades in place of feathers. In addition to their normal offensive and defensive properties, Cirucci can remove these blades and fire them through the air or summon them back at her own will. Her wings and feathers vibrate at high speeds that increase her attack and defense capabilities. Her arms also become long and she gains sharp claws on each hand, and she forms a long, thick tail. Armor that resembles the spinning disk of her zanpakutō appears on each of her shoulders. Her mask grows into 'feathers' flowing from her forehead, down her back, and then coming out from each side at her waist. Cirucci's release consumes her spiritual powers rapidly, but she can get around that problem by ripping off her wings and long claws, instead using the tip of her elongated mask to collect spiritual energy and use it to fight with an energy blade at the tip of her tail. This change is permanent, akin to amputating limbs.
