A clone that walks on its own. A dog that may refuse to obey. A puppet on strings you can break and repair. And a beast under a seal that will one day break free.
Clones — split your chakra, take their own turns and burst from a single hit
Pets — tamed right in the location; loyalty decides whether the beast obeys an order
Puppets — a puppet is an item: it wears down in battle, gets repaired in a workshop and carries its arsenal inside
The Inner One — speaks from under the seal in a voice full of static, shares power only with consent, borrows the body and one day breaks out
All of it is set up in technique and NPC cards, and the game master switches the module on in world settings.
