Sadi has long unkempt orange hair and bangs that covers her eyes. She resembles a dominatrix in design.
She dresses in a very skimpy red (hot pink in the anime) devil-themed outfit. Her outfit covers only the top half of her exposed breasts with laces that hang down that are also featured around her waist. She has long sleeves that slope into stylized rips. She has a yellow ring on the center of her stomach connecting one strap from above and two from below. </span>Around her neck, she wears a scarf-like cape that is white on the outside and pale pink on the inside. She wears candle-shaped earrings and high-heeled shoes that come to a curved tip decorated with spikes. She carries around a pitchfork and wears a headpiece that resembles horns.
As a child, she wore a black headband and dress. She also had black shoes, and hair that covered her eyes. She is depicted as standing next to a small make-shift grave, mourning over a hamster.
Sadi is a sadistic person who enjoys bringing pain and torture to others, including Marine allies. She gets sexually aroused when she hears people's screams of pain. Her over the top reactions and flamboyance cause her to be more of a comical character rather than a sexual one. She also seems to have extreme pride in the virtually perfect defenses of Impel Down, and refuses the assistance offered by the Marines.
She also tends to put "mmmmm--!?" in the middle of her sentences, and insists on being addressed as "Sadi chan", much as a dominatrix would insist on being addressed as "Mistress".
Abilities and PowersEdit
Sadi is a chief guard of Impel Down with some authority over lower ranking subordinates. Being in command over the Four Jailed Beasts, she is considered "stronger than four of them combined", much that they cower in fear whenever the sadist gets angry. During her fight with Ivankov, she was shown to have amazing evasive abilities and was able to keep up with the okama's speed.
The pitchfork she carries around conceals a custom-designed whip which she can use adeptly. With it, she took out a section of the thick stone bridge over the Pool of Blood during Luffy's and Iva's mass breakout.
- Sadi whips at her opponents with her pitchfork-concealed whip. This attack is strong enough to smash the stone bridge in Impel Down's Level Four.
During her childhood, she appeared to have a pet that she was very fond of but sadly died for unknown reasons. The death of her pet seemed to have effected her quite emotionally at the time. She then buried it and gave it a proper funeral.
Impel Down ArcEdit
Sadi was first seen standing outside the gates of Impel Down, refusing the assistance of the Marines in capturing Monkey D. Luffy, and ordered them to fortify Impel Down's outer defense instead. When Impel Down's forces were gathered in Level 4, she was shocked after hearing the Minotaurus' defeat, and was later assigned to guard the entrance to Level 5, where Magellan deduced Luffy will head, with the assistance of three remaining Jailer Beasts. She was then seen serving sake to them while waiting.
After Luffy's capture, she went to Level 3 and ordered the Jailer Beasts, as well as her other subordinates, to hunt for Bon Kurei, who slipped to Level 5 with them unaware. Sadi became very angry over the Jailer Beasts' failure to locate him, violently whipping them as a punishment.
After Luffy, Emporio Ivankov, Inazuma, Jinbe and Crocodile escaped from Level 6, she was ordered by Hannyabal to go down to level 4 to confront them herself. She is seen with the other guards showing shock after Luffy, Jinbe and Crocodile effortlessly defeated three of the Jailer Beasts. Angered over this, she goes on the attack herself, using her whip to knock out a huge amount of prisoners, taking out a chunk of the bridge over the Pool of Blood in the process. Luffy nearly attacks her, but Iva throws him over the Chief Guard and battles Sadi herself.
In their battle, Sadi further demonstrates her abilities, capable of dodging most of Ivankov's attacks with extreme agility while destroying the environment around her, whipping with formidable strength. Despite her efforts, Ivankov managed to steal her whip and she was revealed to have lost the fight and, among other injuries, has had her back hurt. Having been tied up with her own whip hanging from the ceiling, Magellan ordered his subordinates to untie her.
Later, after her recovery, she wakes up the Jailer Beasts by lashing them and orders them to go up to Level 1 to stop the riot on that floor.
