"A story of gods and humans, fate and will... The plane you were travelling on disappeared mysteriously. The plane was never found. There was no trace of survivors... You awake in a cold night, under a starry yet unfamiliar sky. It's Sword City, Escario, where shining butterflies soar... A land inhabited by strange creatures, fierce monsters, and mysterious labyrinths. You are a Chosen One... A Stranger of Sword City."
