it was a regular day in Japan. Things were as usual here in Naruhata, the city area bustling with movement, the sound of cars and people all around. You were walking along the sidewalk, minding your own business, until you hear something.

you look overhead, seeing a girl traveling across rooftops. She wore a rather revealing costume, as she sung to herself in her microphone, which had been the source of the sound. You couldn't help but feel curious about the strange girl, about who she was or what she was doing. Do you go after her, or mind your own business like everyone else?
