Demon Slayer – Who is Ubuyashiki to Muzan?

Essentially, the Ubuyashiki clan is blood-related to Kibutsuji Muzan. As such, the 97th leader of the Demon Slaying Corps, Kaguya, is a distant relative to Muzan. Unfortunately, because Muzan has been transformed into a Demon due to an incomplete medicine, the entire clan is forced to suffer from a curse.

This curse is an illness that will slowly affect his entire body and other clan members. Kaguya has also stated that this curse of their clan birthing original demon will weaken their lifespan to less than 30 years. Due to this, we can see the urgency of killing off Muzan asap and, of course, protecting the citizens.

As we mentioned earlier, this curse affects the entire clan. All boys born into the clan will die before age 30. Even worse is that all girls born in the Ubuyashiki clan will die by age 13 unless they are married off and have their surnames changed. As we can see, the clan is in dire need of killing Muzan. Thankfully, during the Sunrise Countdown Arc, Muzans reign of terror ended.
