Erotic Whistle: Pleasureful Sound Chain

An illusion that relies on the sound of the whistle. Whoever hears it will be assailed by the vivid sensation that they are about to partake in sexual activity with the caster of the technique. Even with 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.
