Knowing Red, Blue and Torch had started the ambush, Ace also started. And his target was the vampires and vampire servants in the back.
Four ace cards and a joker card flew towards the middle of the vampire formation simultaneously. They then exploded one by one causing AoE damages to several vampires and vampire servants.
"Ahh…," A vampire servant wailed, as his HP was cleared. He didn't have an opportunity to respond at all, before dying. His body then fell down with the refugee that he had brought. Also died.
"Help!!!" A vampire fell down after one of her wings was torn, because of the attacks. Her HP was almost wiped out.
In this ambush, the vampire servants all died. The rest of the vampires were injured to various degrees. Even the kidnapped refugees that were carried by them suffered heavy casualties. Only Hugo, Freya, and Mila who was brought by Freya were unaffected. It was mostly because they were in the middle of the formation.
