Curse Technique: Fool's Gold

is a technique formulated by Natsubi for infiltration purposes. Upon consuming and ingesting the blood of her designated target, she can use it for two purposes. The first is perfect replication, nay embodiment. After consuming the blood of the individual and activating this jutsu, she captures the target down to the most minute detail. This includes blood type, summons, appearance, abilities, personality, and even their quirks/idiosyncrasies. In a word, she becomes the victim, taking their place after disposing of them. Placed side by side, she and her victim become indistinguishable even to dōjutsu such as the Byakugan. This is done because the consumed blood contains a piece of the victim's essence, one that is assimilated into her body and rapidly reproduced till she is them.

The other route is a reversal. Upon establishing the spiritual link through blood ingestion, she forcibly converts the target into a perfect replica of herself. They possess her abilities, inclinations, and everything that make her, her. Those who interact with this "Natsubi" remain none the wiser, while the original is able to collect the information and knowledge that "Natsubi" gathers. They're only revealed to not be Natsubi if she severs the connection (dispelling the transformation) or if they're defeated/killed. She often employs them in combat settings.
