Plot
During the Labyrinth City Arc, The Dog-Head Ancient King suddenly appears within the summoning circle during Pandragon's ritual to summon a floor boss in Area 66 of the Labyrinth.

Unlike previous demons or demon lords, the Dog-Head Ancient King was not hostile and showed no intention of attacking Satou and his group. He is also capable of normal rational speech and even gives advise to Arisa about the god fragments inside her body.

Although intent on leaving at first, the demon lord stops to speak after seeing through Satou's fake stats, but seems to mistaken him for some unknown individual. After revealing that his intention is to destroy the god's temple and their followers, which Satou realises includes Sera Oyugock and the innocent priests and mikos he has met during his journey, Satou immediately engages the demon lord in battle.

Satou teleports both himself and the demon lord to a desert far from Labyrinth City before the commencing with their battle. Although neither side could gain an advantage over the other, the intensity of the battle causes earthquakes to be felt hundreds of miles away back in Labyrinth City.

As Satou questioned the demon lord about his hatred of the gods, Satou also begins to question whether the god's motives were truly good for mankind, citing the lack of development despite the existance of magic in this world. This hesitation however is put at ease with the sudden appearence of goddess, that Dog-Head Ancient King considered as Parion, before the combatants and points out the flaws in the demon lord's argument.

Now convinced that Satou is lap-dog of the gods, the demon lord attacks with renewed intensity. Armed with new knowledge instilled by goddess, Satou succeeds in persuading the demon lord by questioning his motives and pointing out the glaring flaws in his argument. Unfortunately, devestated that the deeds he has done and the countless innocent lives he has taken for aeons may have all been a mistake, the demon lord loses his mind and transforms into a giant wolf, intent on the destruction of everything. Unable to calm the now rampaging demon lord, Satou finally destroys him by first sealing off the combat zone with a massive ice wall, before casting Meteor Shower 10 times directly on top of the demon wolf.
