Touya and the others head to ruins on a new quest from the Guild to defeat a dullahan. There they encounter the ancient royal capital, abandoned after the capital was moved a millennium ago.
After finishing their quest, Touya and the others explore the underground ruins for treasure. Yet what they find isn't a mountain of treasure, but a magic beast made of crystal!
No attacks work on its hard body, it absorbs magic, and it even regenerates from wounds. Touya and the rest struggle against such a powerful creature...
What on earth is the true identity of such a magic creature?!
But maybe there's something valuable here
لكن قد نجد شيئاً قيّماً هنا
Aber vielleicht gibt es
hier etwas Kostbares,
Pero tal vez haya algo de valor
Pero tal vez haya algo de valor
Tu n’as sûrement pas
conscience des trésors,
Però potrebbe esserci 
qualcosa di diverso ma di valore,
M-Mas talvez tenha algo valioso por aqui
Но, может, там есть нечто ценное,
