Manmade System In Monstergirl Land

His Uncle who he had been living with died and his Aunt in her grief exiled him to Sweet Devil Town. A place for bastards and failures to be thrown against the quarantined Devil Dungeon. Armed with only the System his Genius uncle built before he died Vergil must survive to find out why his uncle died. But he can't show his face back at Ironborne city without power of his own. The Luna family won't allow him to survive long. Can he fight his way back or will he die like many exiles before him. Current technology mixed with syfi and modern magical creatures.
