The dungeon master of Selen has appeared, and the dungeon is deemed off-limits until it is defeated. Only a party of three adventurers with very high stats may challenge the powerful dungeon master, but Ryota has a plan...
It's amazing that just 
three of you defeated it.
.إنه لأمر عظيم أن ثلاثتكم هزمتموه
Wahnsinn, den zu dritt zu besiegen.
Es increíble que ustedes tres solos
fueran capaces de derrotarlo.
Es increíble que solo vosotros tres
hayáis podido derrotarlo.
C’est dingue
que vous l’ayez eu à trois.
Siete incredibili!
Que incrível! Derrotaram só em três.
Вот это да. 
Победили его втроём!
