Bunakkabyō

The Bunakkabyō (分悪化病, Division Degeneracy Virus) is a unique virus capable of halting and  within targets.

When initiated, the Bunakkabyō infects the target on the cellular level, destroying the in its entirety while preventing its regeneration and completely halting. As a result, the target's cells are rendered incapable of division, thus terminally shortening the target's lifespan, while making healing impossible. Because this stops the production of, the target is incapable of producing antibodies, while also making any immunizations previously acquired obsolete. As a result of the virus, not even pathogens within the target's body are capable of division. The effectiveness of the Bunakkabyō is so immense that it is capable of disabling powerful such as the  and healing abilities such as the.
