Misumi Tozawa, known as Mito in Sword Art Online, has teal eyes and long purple hair typically worn loose in the real world. Her school uniform features a red bow tie, an amber sweater, a brown skirt, and thigh-high socks. Outside school, she ties her hair in a ponytail and dons plain, baggy street clothes with a cap. Her initial Sword Art Online beta test avatar was a tall male character with light purple hair, a chin beard, red eyes, and a feminine one-piece outfit complete with thigh-high boots and a white cape. Following Kayaba Akihiko's tutorial, her avatar updated to closely mirror her real-world appearance while keeping the original outfit; she later dyed the avatar's eyes red and adopted a braided hairstyle courtesy of Asuna. During gameplay, Mito wielded a scythe as her primary weapon. Her attire varied, including a black-and-dark-blue outfit with a tattered cloak on Floor 3 and a sleeveless reddish-brown top with a dark blue chestplate on Floor 5. In reality, Mito was an elite gamer proficient in competitive titles like Tekken. She introduced Asuna Yuuki to Sword Art Online to help her manage academic and familial pressures, marking Asuna's first VR gaming experience. After the game became a death trap, Mito used her beta tester knowledge to mentor Asuna in combat and survival, forging a close partnership. This bond shattered during a Floor 1 battle against nepenthes: Mito abandoned their party to chase a rare monster, leaving Asuna exposed to a monster swarm. Panicked by Asuna's declining health, Mito dissolved their party, inadvertently isolating Asuna mid-attack. Mito later joined the assault on the first-floor boss, Illfang the Kobold Lord. She aided Kirito and Asuna in defeating it after leader Diabel fell. Post-victory, she apologized to Asuna for her earlier abandonment, citing fear and self-preservation. Asuna declined to rejoin her party, opting instead to advance alongside Kirito. Mito's actions fueled Asuna's initial despair yet also shaped her resolve to survive independently.
