Demonic Flute: Phantom Sound Chains

A genjutsu that relies on the sound of the flute. Whoever hears it will be assailed by the vivid sensation that their limbs have been fastened with sturdy ropes, thus becoming unable to move about freely. Even without physical intervention from an outside force, the body is robbed of all mobility, and consciousness itself progressively fades away. At the same time, they are fed morbid hallucinations, which makes it also possible to run them down mentally. Given that the means of transmission is sound-based, it has a large range of effectiveness, on top of which it can be applied even without knowledge of the enemy's position, which makes for an exceedingly convenient technique.
