Furthermore, as demonstrated by her nurturing relationship with a young Perlica—who viewed her as an older sister figure—M3 possesses a caring nature, willingly taking on a protective and supportive role for those around her.
Abilities
Classified as an Elite Operator within Endfield Industries, M3 possesses combat abilities that qualify her for top-secret and high-danger field operations. Her operational scope centers on executing covert and hazardous combat assignments that standard personnel cannot handle, utilizing her specialized equipment such as the mechanical unit attached to her right arm.
Background
M3 is a veteran member of Endfield Industries whose history with the organization stretches back at least a decade, as revealed in the official comic Promise. Remarkably, her physical appearance has remained completely unchanged throughout the years. During this past period, she played an instrumental role in taking care of Perlica during her childhood, acting as a guiding presence until Perlica matured into her role as an inspector.

Trivia
Her designation M3 is widely presumed to stem from Mon3tr, the creature residing in Kal'tsit's spine in the original Arknights. Prior to official localization during early beta phases, fan communities dubbed her Gyaru-tsit due to her visual resemblance and casual aura compared to Kal'tsit. Online discussions often note that searching for her name can yield search collisions with the common abbreviation M3, which refers to skill mastery or module upgrades in the main game.
