Asuna Yuuki is a young, helpful girl trapped in Sword Art Online, much like Kirito, unable to abandon those in trouble. She takes the game very seriously and focuses on clearing it. Initially driven solely to escape regardless of others, meeting Kirito transforms her, making her cherish his words and act tsundere toward him even after marriage. She boldly fights on the front lines with her rapier despite her healer role as an Undine in ALFheim Online, earning the nickname 'Impetuous Healer.' Her avatar changes to light blue hair, clothes, and eyes. She heroically overcomes paralysis to shield Kirito from a fatal blow during the final battle against Kayaba Akihiko.
