Fai is a simple girl that loves eating, going on adventures, and punching things. Whenever she is hanging out with her friends, Fai is always smiling and laughing. Fai never lets anything upset her and always finds a way to have some fun. With her easy going personality and her simple tastes, it is easy to relate to and root for Fai.

Fai is an energetic and upbeat girl. Unlike her teammates, Fai always jumps into things head first without thinking too much. Whether it is fighting off monsters or jumping into random pits, Fai always approaches things with her carefree attitude.

When coming up with names for her attacks, Fai takes a literal approach. Her attacks have names like Pounding Knuckle and See-Lots-Of-Punches Punch. While the attacks might not have the most creative names in the world, they do have a certain charm about them. All of her attack names are funny and just help show off her unique personality.

Fai shows off her wild side as she bonds with the monsters she comes scross on her adventures. Thanks to Fai's intuition, she is able to bond with the various creatures she comes across in an instant. We see her bond with powerful monsters like the horned gorilla and see her instantly understand the language of the Tarka. These are always some of Fai’s best moments as she shows just how special she is.

Fai loves food a lot. Throughout the series, we see Fai talk about and enjoy food, but what happens when Fai isn’t full? Chew on Sei's elf ears, of course. No matter how many times it happens, the scene is always cute and funny.
