A member of the guild «Black Cats of the Full Moon». All the members are actually computer research club members from the same high school in the real world except Kirito. She uses a two-handed long spear and her level is rather low compared to the rest of the guild members. She never intended to leave the Starting City but she did, knowing that she probably would die because she is afraid of monsters. According to Kirito, she and him are a lot alike and are both socially awkward, wall themselves in from people but fear loneliness.
She died along with 4 other members from the guild, as they were lured into a trap filled with monsters. Even in her final moments, she still believed Kirito would protect her. Her final words to Kirito were “Thank you, Goodbye.” She leaves a Kirito a Christmas message were she hums “Rudolph the Red-nosed Reindeer” and thanks Kirito for all the time they had spent together.
