Fio is one of many fairies in a land filled with tickle monsters who feeds off human AHA energy.

Fio sought Lena the young Spellsword's help to free several of her friends from captivity. They got through the journey together then cured Lena's mother Remilia from a troublesome illness.

Fio uses light magic, healing, support, and debuff spells. She often gets Lena out of trouble when she gets captured.

Although she and Lena are best friends, Fio will never understand her obsession with pots.
