Mildo is a supporting character from the anime Jormungand who serves as one of Curry's two bodyguards. She is a fair-skinned woman with light brown hair and brown eyes, and she is often seen with rose-tinted sunglasses perched on her head, even during missions. Her preferred weapons are combat knives and machetes, as she is a knife-trained mercenary who relies on close-quarters combat skills.

Mildo's personality is defined by a short temper and a tendency to act on impulse. She is quick to kill anyone who annoys her, even if doing so interferes with her employer's plans, and she frequently disregards Curry's orders. This recklessness stems from an underlying restlessness; she appears to be trying to fill an emotional void through combat and genuinely relishes the thrill of fighting. Her short fuse has led her to kill one of Pollack's men out of annoyance, forcing her colleague Lu to shoot another to protect Curry.

Mildo harbors an obsessive crush on Valmet, a fellow warrior whom she deeply admires. This admiration drives her to seek out fights with Valmet repeatedly, though she has never managed to win against her. The rivalry is one-sided in its intensity, as Mildo's fixation is not reciprocated. Her role in the story is that of a secondary antagonist aligned with Curry's organization, often clashing with Koko Hekmatyar's group. She does not undergo significant personal development across the series, remaining consistently driven by her combative nature and her fixation on Valmet. Her notable ability lies in her knife combat training, which makes her a dangerous opponent in close-range encounters.
