For the third fight, Rein was chosen once again. This was the worst possible outcome of the dungeon master as with the random chosen system, he was trying to get the other girls on the stage more and not Rein.
But he was unwilling to throw another match without trying. So he decided to go all and took out the strongest opponent he could choose for this floor.
Even though he was the dungeon master, the dungeon itself had various restrictions. So he was unable to use just any boss in any stage. So he decided to use the strongest boss he had available for this round to test Rein.
...
After Rein entered the arena, three figures appeared before him. At first Rein thought that the dungeon master was somehow bending the rule to allow three opponents to fight him, but after a quick analysis he saw that the three figures in front of him were part of just a single monster and not three different ones.
