Jimetsubyō

The Jimetsubyō (自滅病, Self-Destruction Virus) is a deadly virus capable of sensing hostile intent within infected targets. Once infected, should the virus detect a given level of hostile intent, as predetermined by the user, it will take over the mind of the affected, inducing extreme suicidal behavior within them. From here, the affected individuals will attempt immediate suicide in the most effective and efficient manner possible.

A secondary use developed by incubators of the virus is self defense. Because the virus is capable of sensing hostile intent, users are able to utilize the virus within their own body to sense negative emotions of targets around them and react accordingly. Because the virus takes over the mind of the target, it is capable of autonomously engaging the motor functions of the user, allowing them to dodge attacks without consciously thinking to do so. The virus itself has displayed the ability to adapt over time, allowing it to induce stronger suicidal thoughts in targets as well as react faster to hostile intent the more it is used.
