Originally Zatiel did not intend to fight alongside the Imperial Depravitas during his mission in Abyss or Baator. Still, due to the paranoiac nature of Archdevils, things went a little out of hand.
The Archdevil that dominated this city had the name of Horun and was supposed to be a weak Beyond Limit Stage existence.
However, not only had Horun hidden his true power for thousands of years, which was at the Middle Beyond Limit Stage, but he also took a powerful drug that pushed him to the peak of the stage as he saw the might of the Corrupting Mist and Zatiel.
If the Neo-Demon had taken a few years to research this Archdevil personally, he would have noticed Horun's true power and hidden tricks. But none of that mattered anymore.
Zatiel did not waste even a second thinking about what could have been done differently and instead summoned the Imperial Depravitas to his side.
