Filo

Filo (フィーロ, Firo) is a secondary character on Isekai Quartet.

Appearance
Filo is seen in either her Filolial form or her human form;

Filolilal
In her true form, Filo resembles a white Filolial Queen with pink and white feathers, yellow beak and feet, blue eyes and a blue-collar around her neck. She is also seen with the accessory attached to her feathers that Naofumi gave her before the third wave of catastrophy in The Rising of the Shield Hero.

Human
In her human form, Filo gives off the appearance of a young girl with blonde hair with a cowlick that reflects her status as a Filolilal queen and blue eyes. She also has white wings on her back and wears a white and blue dress with a dark blue ribbon on the chest. She still wears the accessory as a hairclip.

Personality
She is somewhat childish and loves to play around with people she deems safe to play with

Plot
After being teleported to the world of Isekai Quartet, she ends up in the animal stall with Dread Knight and Hamsuke. She reunites with Ralphtalia and is nearly hit with a baseball hit by Mare, but is saved by Naofumi.

Trivia

 * The presence of the cowlick seems to indicate that Filo and her friends were teleported to the school sometime after the Fourth Wave.
