Attacking The Cult Members
-----
Their black clothes were enchanted with the shadow element, and were also drenched in demon blood, cursed equipment. Alongside that, their equipment was enchanted with runes that enhanced their stealth and camouflage, quite high-quality ones. Lastly, they held daggers coated on demon venom, and had all sorts of abilities and magic, alongside spiritual power in par with Rank 2 Spirit Masters.
And above all, they had red marks on their hands, showing the sign of a fly made of red blood color, their hands were glowing with maliciousness. I can tell they're hired spies and assassins by the Beelzebub's Cult, just by seeing that fly-like mark.
"For now, spy them and listen to whatever they're talking about."
I told the two to just spy them for now. The two spirits quickly melded into the shadows of the group of spies, as they heard them talking while I pretended everything was fine with Erika and her mother.
