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?!
If I could use Gate like you, 
I'd go buy some every day.
لو كان باستطاعتي استخدام بوّابة مثلك، لذهبتُ
لشرائها يومياً
Wenn ich Gate benutzen könnte,
würde ich jeden Tag dorthin gehen.
Si pudiera usar Gate como tú,
lo compraría todos los días.
Si pudiera usar Gate como tú,
lo compraría a diario.
Si je pouvais utiliser Gate,
j’en achèterais chaque jour.
E se potessi anch'io usare il Gate,
Se eu pudesse usar Gate, 
compraria todos os dias.
Если бы я могу использовать «врата»,
то я бы каждый день покупал.
