The Sano Faction.
More specifically, the Sano Yuka Faction.
Among all the factions that had emerged from the new generation of demons, the Sano Faction was currently considered one of the most capable and well-established groups. Its reputation wasn't based on a single powerful individual either. The faction had accumulated a surprisingly large army, and the majority of those soldiers were demons who had already proven themselves to be competent in actual combat. On top of that, the number of demons belonging to the current generation was exceptionally high compared with the other newly established factions.
That combination gave the Sano Faction a considerable advantage.
They had numbers, they had talented members, and they had a leader who knew how to make all of those things work together.
