Desire Unleash

Desire Unleash (欲望開放）is the second supernatural phenomenon by Heartseed that the StuCS experiences. This phenomenon first appeared in Kizu Random but would later reappear in  Asu Random II, plaguing the first year students.

Description
As the name implies, this phenomenon forces a person to give into their impulses and desires, completely disregarding any restraint they would normally have. As such, even impulses to steal or murder can potentially be unleashed. When the phenomenon activates is completely random, but it seems to be more prone to activate when a person is experiencing more acute emotions. Apparently, when the phenomenon activates, the person can hear a voice in their head commanding them to act out their impulses.

This phenomenon demands immediate gratification, so if the desire is a task that would take a long time to carry out, the impulse may peter out before it is completed. It is suggested that an unleashed desire can be overridden by an even stronger desire, but this theory was never successfully implemented.

Trivia

 * Compared to the novel/manga, in the anime, this phenomenon is significantly toned down due to the darker and inappropriate content.
