Free Isekai Idea: A college student dies of meningitis because they forgot an appointment, and wakes up with a doll hand in their face. They've been manufactured as a new type of doll by a magical golem rebellion. With realistic flesh and eyes, they're designed as an infiltrator.
They're one of a series of 500 identically faced porcelain doll golems covered with undead flesh with glass eyes. Their endoskeletons are made of mithril or whatever, are nearly indestructible, and they weigh 3 times the mass of a regular human. But otherwise same strength.
They're then dropped off individually all over the continent to infiltrate the soldiers trying to suppress the golem rebellion but resisting their programming, they join a band of soldiers fleeing a surprise attack that annihilated their entire kingdom and decide to help.
They eventually start a relationship with one of the soldiers when their band is hit by much more fragile porcelain doll weapons and everyone else dies. They spend forever crawling through doll-infested territory and kill one of their copies preparing to assassinate someone.
Someone else guessed it, but the regular dolls have no "souls" so to speak. Their ability to network forms a gestalt intelligence, but they are searching for something greater, an isekai'd soul ending up in a doll is no accident, nor is their ability to resist the programming
