Brunhild is from an otome game called "Wizardess Heart"

Name: Brunhild (Eress)
Age: ???
Gender: Female

Eress is a fairy that is introduced in Joel's route when both him and Icy save her from frogs. Due to the temporary decrease of her magical power, she losses her memory and can only maintain her reduced form, causing her to be mistaken for a bug at first sight. Brunhild is Eress’s true identity/form. Brunhild is the daughter of the Fairy King: King Oberon.


Personality:

Eress has a short temper and is easily offended (especially when being called a bug.) Eress dreams about true love and keeps her promises to the very end.
We would like for her to have  a more deeper, soothing, and elegant voice. However we entirely open to your own interpretations! Voice Example (The first voice): https://shortcut-test2.s3.amazonaws.com/uploads/audition/file_path/615165/Eress___Brunhild_-_Wizardess_Heart_-_Tomatoadz.wav
