Suddenly, a powerful red energy shot out from Klaus, parting the clouds above. It created a force field around him, which blew away the approaching Zombie Princes, sending them flying several kilometers by the sheer chaos of the strange energy.
The red moon, which had been fading, started glowing again, this time turning a deep crimson. The clouds overhead grew darker and more ominous.

Back in the meeting room, the cold-looking lady who had been watching the battle closely continued to observe as Klaus killed the five assassins. Then, the Great Sage assassin appeared. She almost gave the order to fire the missile again, but when she saw Klaus suddenly energized and fighting back, she hesitated.
Then, the Zombie Kings, having completed the Blood Moon Ritual, began appearing one by one, pushing Klaus into a corner.
