Misa Saotome, the third of nine sisters, serves as a Valkyrie dispatched from Asgard to defend Midgard against demonic threats. Her specific designation is Ortlinde, the Valkyrie of the String, wielding the Holy Sword "The String." This weapon grants her the power to manipulate strings and fabric, a versatile ability applied in both combat and defense.

Physically, Misa possesses distinctive green eyes and short green hair, which she frequently styles in various ways. Her stature is notably tall.

Her personality is sociable and easy-going. As one of the older sisters, she naturally adopts a protective stance towards her younger siblings, leading them to frequently seek her guidance and support. This dynamic positions her as the group's leader when the sisters act collectively. Within the family, she carries a reputation originating from their time in Asgard as a romance expert among her younger sisters. However, this perception contrasts with reality, as she lacks any actual romantic experience.

Her name carries specific meanings: "Misa" combines the characters for "three" (三, "mi") and "sand" (沙, "sa"), while "Saotome" derives from "already, now, fast, early" (早, "sa") and "virgin, maiden, girl" (乙女, "otome").
