"Puppet's Droplet (Kugutsu no Shizuku)"
- Plants bacteria in the target's brain to brainwash them. - In addition to causing hallucinations, it can trick the part of the brain that controls power to draw out superhuman physical abilities and strong fighting instincts. Because of this, those who only know a fraction of his power misidentify it as "Physical Enhancement." - Any creature with a brain, such as crows or mantises, can be a target. For creatures smaller than humans, brainwashing and physical enhancement are completed in a short time. - Conversely, brainwashing humans requires a significant amount of time, making it difficult to achieve during active combat. - Even if Ukyo dies, the brainwashing remains and can only be released by Ukyo's own will.
