A dancer who refers to herself as "Watashi" (polite/feminine). She is bright and cheerful, often speaking and acting in a bewitching manner, yet she possesses a shrewd, calculating side. She has a curvaceous, "dynamite" body and overflowing maternal instincts. She has captivated countless males and rules the underworld extensively through her charm alone. As a dancer, her specialty is seduction. Those charmed by Mata Hari become her captives and cease all action; their nerves become hypersensitive due to excitement, increasing the damage they take from her seductive attacks. Her seduction techniques are of a terrifyingly high dimension, capable of charming even inanimate objects like weapons or golems. Since her seduction is a form of dance, she can target multiple people simultaneously. Mata Hari's combat style involves charming enemies to render them immobile, then using that opening to stack Charm while gradually chipping away at their Willpower. Finally, she uses her full-power seduction to overkill their Reason, causing a mental breakdown through overwhelming pleasure. She fights while reveling in the pleasure of toying with men. As a hobby, she once took on a party of top-tier adventurers alone, charming and subduing every single one of them. While it is hard to tell because she focuses on seduction, her physical abilities are also considerable. She uses her dance movements to fight acrobatically while weakening enemies with her allure. She fights while scattering heart-shaped effects. To enjoy the enemy's reaction, she sometimes mockingly targets the groin area. Mata Hari possesses innate, always-active skills called "Pheromones" and "Intoxicating Fragrance," meaning she has the natural talent of a dancer to make surrounding men go into heat just by standing there. Mata Hari's skills as a dancer have reached the level of magic. Through her voluptuous dancing, she can seduce the males around her, performing a dance so intense that just watching it can make them reach their limit. Watching males are implanted with primal desires and are subjected to violent pleasure by the carnal and lewd dance of Mata Hari, the ultimate female. Even though they are only watching, they experience a more intense and effective pleasure raging through their bodies than if they were being directly caressed. As long as one is male, there is no way to resist. If one continues to receive such techniques until their Reason is gone, they will inevitably experience despairing pleasure and become unable to recover. Perhaps for this reason, to ensure the battle doesn't end too quickly, Mata Hari does not use her full-power seduction until she is backed into a corner or her mood reaches a peak; instead, she performs her seductive dance while holding back.
