Takeda's shikigami watches an opponent use a cursed technique, records it, and lets Takeda replay it once. One observation, one copy, one use, then the recording is erased and Marmalade Boy needs to observe the technique again. The shikigami is small and fragile, meaning Takeda has to protect it during fights while maneuvering it into position to witness technique activations. The payoff is substantial: a single copied technique used at the right moment can turn a fight, but the setup is risky.
