The girl's senses returned with a sharp, piercing pain.

A clinging darkness like viscous sludge.

When a single ray of red light pierced that closed world, the girl finally awoke.

When a strange red bird handed her a purple sphere, two memories mingled within the girl.

The girl's goal is to live out her predicted sixty-year lifespan.

But wanting to live a fulfilling life, she dives into all sorts of endeavors.

As she is frail, she must also train her body.

This is the story of a girl who, living life with urgency, strives to live strongly, robustly, and boisterously.
