Sango first appeared as a hologram in The Ancient Poké Ball, silhouetted with two other Admins, Onyx and Agate.
In HZ016, she appeared again as a hologram, this time not silhouetted and along with some of her fellow admins, talked to Spinel after his failure in having Liko's pendant taken away from him.
She made her physical debut in HZ024, where Hamber requested that Sango and Onyx accompany him to the Old Castle in the Galar region. They planned to meet with Amethio, Zirc and Onia and assist with pursuing a mysterious Pokémon that emerged from Liko's pendant. Shortly after arriving, Sango ignored Hamber's orders to stay behind and attacked Liko and Roy, only to be stopped by Captain Pikachu. Once Cap took out Onyx's Garganacl, Sango snapped and ordered her Glalie to use Self-Destruct, giving Friede the opportunity to take Liko and Roy to safety. After the Rising Volt Tacklers fled the area, Sango was scolded by Onyx for her reckless behavior.
In HZ027, Sango appeared with Agate and Onyx waiting to meet to discuss the Explorers' next goals. While she waited, Sango seemed very impatient and this angered Onyx, who blamed her for the failed mission in Galar. During the meeting, Sango was teasing Amethio about what happened in the previous mission and together with the other members of the Explorers they decided that they would follow in Black Rayquaza's footsteps.
Sango appears to have a mostly cheery and playful personality, she also has a teasing side as well since she often likes to disrespectfully poke fun at and ridicule other people easily, such as her fellow admins Spinel and Onyx. Sango is along with Onyx, known as "the troublemakers", being less disciplined and more aggressive than their fellow admins. Sango in particular appears to have a very volatile mood that can become extremely violent in an instant, which was seen during the siege on Diana's castle, where she commanded her Glalie into using Self-Destruct under a fit of rage, against Onyx's own protests that it was reckless.
