Summary
The Demon that Giluas defeated regains consciousness and tries to attack Lurie and Alma, but Matty steps in its way to block the attack. Astounded by this outcome, the defeated demon acts as a proxy for the mastermind demon to relay a message to Matty revealing it'll soon destroy its seal and completely revive. Its host demon then disintegrates into dust and Matty deduces that the demon Matty talked to within the dungeon was the mastermind behind the demon city as well. Just then, Giluas asks for help and Matty heals him and both Lurie and Alma notice that with the demons defeated all of the town residents have been freed from their Thought Paralysis spell. Hence, Giluas uses his authority to take control of the situation and appoints the factory foreman as the provisional lord of the city.

At the front gate of the city, Giluas gives Matty a permit to enter Folkia's restricted area, and with that the group parts ways with him. Arriving at their destination, Matty opens up the entryway and leaps into the pit below to enter the ruins. Once everyone was inside of said ruins, Matty splits the group up to find any weapons, but Iris heads off to search for food. With everyone gone, Matty starts to power the ruin's core, until Lurie returns with a sword that he created in his previous life. Alma then returns with a heavy spear she thought would be good for Iris to use, however, Matty admonishes the idea due to the spear's magical properties. Iris then returns with a box of canned preserved foods with a preservation spell cast on them, however, due to the long duration of time past, it still expired. The ruin's core is now fully charged and it's used to track the Mastermind demon's location with the help of a part from the factory. It's also deduced that the demon's plan is to wipe out Humanity as a whole. After using a magistone to help detect and get more information on the demon's location and other information. They learn from Matty the demon's name is Zardias and that at their current strength they're unable to beat it. Iris laments that they don't have sufficient weaponry that could be found there that can help take the monster down, which gives Matty an epiphany. Using the sword that Lurie brought, Matty uses it as a way to search for other magical items that would help them in their endeavor against the demon. Specifically, Matty was looking for a certain sword and as it so happens it was in the kingdom of Eis.

Enroute to the kingdom while riding on Iris' back, Matty gives Lurie and Alma magistones to locate the sword. An outburst of power felt by the group then leads Matty to conclude that Zardias' seal was broken. Matty then orders Lurie and Alma to search for the sword while he deals with Zardias and the two then head for the kingdom's treasury to retrieve the sword. Matty then prepares for the upcoming fight by enchanting his sword and hopes to seal the space Zardias was going to use to teleport to him as a way to either buy time or even damage him. The moment Zardias' portal opens up, Matty tries to seal it, but fails, hence Iris is asked to use her dragon fire breath against him, but the attack was also ineffective against him. Wasting no time, Zardias pulls out a sword and with a single slash attacks Iris. Matty uses multiple barriers to try and protect Iris who dodges the attack just in the nick of time. Zardias then attacks and overpowers Matty who admits he's the most powerful demon he's faced up to that point.

Meanwhile, Lurie and Alma reach the treasure, but the guard there prevents them from entering noting they need permission from the king to enter. Right as they're surrounded by more guards, the king appears and is explained by Lurie of the current situation and allows the two entry into the treasury.

Back outside, Matty struggles to defend against Zardias' attacks and realizes that in order to win the fight, he'll have to give up his life.
