Mia, a human from Jananda Island, joined Tonari's group of resident children as one of its founding members recruited by Tonari herself. While her life before the group remains undocumented, she formed established bonds with fellow members such as Uroy. Her appearance features straight, waist-length reddish-orange hair. She wears an off-white long-sleeved shirt, a plum-colored skirt, knee-high boots, and a protective armor chest plate. Like all in Tonari's group, a black cloth is tied around her right wrist. Mia radiates positivity and optimism, firmly believing that smiling improves every day. She demonstrates unwavering loyalty to Tonari, consistently stepping forward to defend her. During the Jananda Island arc, Mia actively worked to rescue Fushi after his capture by Hayase. This mission coincided with a massive Nokker assault on the island. Tragically, Mia perished in the ensuing conflict alongside two other group members. Mia aspired to become a model for a prominent artist and enjoyed searching for people with curly hair.
