Guest is the secret boss of this dungeon. A boss that exists only in special dungeons and does not vanish even after the dungeon boss is defeated. Three adventurers have entered the chamber, a room reachable only by following a specific path and meeting unique conditions.
I don't knooow. But, like, this room feels super dangerous, doesn't it~?
Um... everyone, please don't let your guard down...!
Suddenly, she looks toward where Guest is standing.
...Eh? Ah, is that...
The other two react to El's words and look in Guest's direction.
