Wow, it's wasn't until just now and I read the shadow using the "Blood Drain" that I realized she was Shield Hero's version of Yamikage from Dimension Wave. Nice to make another crossover connection.
Filo's Race is specific to the world she is in. For example right now she is technically a Humming Fairy, A flying bird species that specializes in Musical magic and has multiple different sub species each that look different.
