The aurora turns out to be harmful, it manages to melt Hajime's prosthetic arm and injure him heavily. The girls freak out, but manage to cover Hajime from further attacks until he regains consciousness.
There is an introduction, and a New character introduced. Freed... and some fighting. (It’s kinda implied that Freed has some connection with Demon Lady from the other dungeon). Hajime is forced to use his limit break to turn things around after Freed uses some teleport magic which injures him further.
Tio fights a white dragon that Freed brought along.
Freed praises Hajime, says something along the lines of if he didn't do a surprise attack, he wouldn't have been able to defeat Hajime. Freed then activates a trap which breaks the static stone that keeps the Volcano from erupting. Freed knows that it would destroy the dungeon and stop anyone from obtaining the god magic, but he thinks it's worth it.
Hajime tells Tio to follow Freed as he flees, which Tio interrupts that Hajime wanted her to save herself and leave him. Hajime assures her that he doesn't plan to give on anything, including delivering the static stone or obtaining the god magic.
Hajime has a plan, but we don't get to hear it. Tio then chases after Freed and seem to kill him, but its impossible to be sure. Tio was about out of gas magically, and couldn't confirm it. Then she flies back to the city while Myuu and Kaori have a bad feeling.
