Yui Aoide

Yui is a sweet and generally optimistic girl, she's a talented conductor who's conducted many of the world's most famous orchestras. Due to this, she's also become fairly good at 'conducting people', she's quick to resolve arguments and break up fights. Despite her friendly nature, Yui can be rather bossy and even somewhat controlling- but she can assure you that it comes from a place of affection.

She has a Princess Complex and hates being seen as plain, often coming off as very vain when it comes to her looks. She thinks beauty is the most important quality in a person.
