It died in a fire, and its soul attached itself to a puppet, becoming a puppet with a soul, but this puppet is no ordinary puppet... "Absorb damage"... As long as it absorbs enough damage, it can control other puppets, and even turn into humans. When the energy is exhausted, it will turn back into an ordinary-looking puppet.

Puppet spirit.
