Mugen Foundation (2018)

A shy high school girl dreams of becoming a fashion designer, but given her personality and lack of communications skills has little hope of breaking through. Instead, she is mostly idle, listless and bored at high school. On her way home one day she hears music emanating from a building. She meets a girl her age singing and playing an instrument. Around the same time a class-mate notices the girl's design book and asks her to join the school's drama club.
