Yui

Meet this bubbly little girl with long black hair, looking like she just stepped out of a fairytale at no more than 10 years old. Kirito and Asuna stumbled upon her in the lush forests on the 22nd floor of Aincrad. What’s wild? She’s actually a mental health support program gone rogue, meant to help players stay sane during the horrific death game. After some serious system glitches, she became an AI with real feelings. Kirito saved her by turning her into a cute crystal pendant. Later on, she pops back into life in *ALfheim Online* as his adorable Navigation Pixie, and they treat her like family!
