A voluptuous woman who is a childhood friend of Balto. From a household of succubi who use their good looks and techniques to manipulate others to do their will. Distrusting the current Demon Lord, she comes up with various schemes hoping to catch her off guard. However, she is not aware of the fact that Ariel overhears them all and that Balto has been covering for her.
Santoria is shown to have a clam and level-headed disposition, this is seen where she chooses to be strategic and subtle when carrying out her actions. This is seen during the The Great Human-Demon War, where Sanatoria preferred to use strategic tactics that effectively insured that her army suffered absolutely no losses when taking the Human Fortresses at the dawn of the invasion.
Sanatoria, like many of the demon, disapproves of Ariel as the Demon Lord and her actions of pushing militarism and war upon the Demon Race during their current predicament of low birth rates and dwindling population. Sanatoria herself has made a point of actively scheming to dethrone Ariel to put a stop to her actions, this is seen where she subtly participated and assisted several revolts against her and is actively trying to overthrow her. However unlike Bloe, Sanatoria is shown to approach this subtly, with her working behind the scenes instead of making her discontent known to her face.
Sanatoria herself is one of the percentage of demons that buy into the rumor that the Demon Lord herself is not as powerful as she claims to be due to her hiding her powers and not flaunting them and believes that it is possible to overpower her with a sufficient number of allies, with her aligning with several of her fellow Commanders and their armies and even with the Elves due to believing that it would be enough to defeat her. Balto knowing of the Demon Lord's overwhelming power and the power of her subordinates, deems Sanatoria to be too foolish due to her obliviousness to the truth.
Sanatoria has a long hair with her left face being covered by her long bang. She is described to have a well-endowed bust, one that Shiro envies.
After Erguner's death, the elves forged a new partnership with Sanatoria and Kogou. In order to take Fort Okun, she sent in a single captured Anogratch to be killed by the humans. She kept her army in nearby, officially to keep the Anogratches from migrating into Demon Realm, but her actual motivation was to keep an army ready to strike against the Demon Lord.
