Last Valkyrie Leafern's Adventure

You are the wing-crowned valkyrie Leafern, last of her kind.
The final battle of the war (Ragnarok) was a terrible defeat.
"...If only I were stronger..."
Leafern lost consciousness.
Norun the goddess was waiting for her when she awoke.
"Your destiny, like mine, was chosen by others.
It is not the destiny you desire. You can change it.
You have the power to overcome."

In an instant, Leafern was returned to the first day she met Norun.
