When he's suddenly transported to a new world called Byston Well, he finds himself transformed into the revered holy warrior known as Garzey's Wing. Tasked with helping the Metomeus tribe gain their freedom from slavery, Chris is ill-equipped for this daunting challenge, armed only with a meager sword salvaged from a fallen foe.
