After exchanging a few rapid blows with Momon, he then escapes as Momon was protecting Evileye from one of his attacks.
He then casts a a wide range spell called the "Flames of Gehenna" around a certain area of the city, summoning countless demons inside it.
Believing Demiurge's story, almost all adventurers in Re-Estize united together to stop Jaldabaoth, and Momon becomes their hidden weapon as nobody except him can fight against Jaldabaoth.
While other adventurers battle against the weak demons, Momon, Evileye, and Nabe fly across the city to strike Jaldabaoth and his group of masked maids.
