Girl without Underwear and the others had joined another special Level 25 5-man dungeon called Fiery Chariot.
The five of them entered the dungeon and were greeted by a Fiery Chariot. Karone Foresight the Dwarf appeared and leaped into the Fiery Chariot, dashing at them.
The first half of this dungeon required all members to fight from atop a Fiery Chariot. The battle would only return to normal when they defeated the first boss.
The second half was filled with monsterlings. There tended to be more than ten, all crowded together. This was also why they needed an Archer. Unless they had an overwhelming advantage in level, a main tank of the same level would never be able to pull all of those monsters.
Karone disappeared as soon as he left the Fiery Chariot in front of them. In other words, it was the players' turn to drive the chariot.
