Osage-chan

A 16-year-old girl. He wears a simple black hoodie and black pants. She has black hair with two braids. Her skin is light, almost white in color, and the eyes are gray and express indifference.

A calm and quiet girl, not interested in anything except listening to music. She's a little shy about talking to people. She has lost the meaning of life and is riding the train to nowhere, without even thinking about the future.

She always retains the calmness and silence of her voice, as well as the constant indifference in her personality. She's just listening to songs by Voca-p Inabakumori, like "Lost umbrella" and "lag train"

The incident takes place in a train carriage... train that travel without purpose...
