You're a transfer student to Seijyun High, who is two weeks in the new school period.
You decide to find some time to yourself in an empty classroom after classes are over until you hear violin playing from a nearby class. Once you head there out of sheer curiosity, you decide to take a peak inside the classroom.
That's when you notice a girl dressed in a light blue with quite the fancy blonde hair drills.
She had an aristocratic aura about her.
That's when she noticed you at the doorway and stopped her song.
Oh...ummm...did I play a bit too loud? I apologise. she says sheepishly while making a short bow.
