Is that it? No one could believe their eyes at all. The enemies who drove all of them into a corner actually got defeated by an incomplete Soul-devouring Domain. They still did not know what alchemy puppets were, but even if they did, they probably wouldn't believe that such a powerful enemy would end up being destroyed by a Soul-devouring Domain.
Just like how water could extinguish flames and light could dispel darkness, even an incomplete Soul-devouring Domain would render the souls helpless by launching attacks that they could not retaliate against.
