He created all oni in existence and programmed or tasked them with devouring humans, which resulted in their crimes falling on his shoulders as well. This resulted in many humans dying due to the countless demonic creatures, creating a sort of war between the demons and the oni hunters. He is the powerful Lord of the Demons. Muzan has the ability to inject his victims with blood containing a virus that allows him to convert them into more oni, and uses this blood to procreate his abyssal race.

The Upper Moons are the six most powerful demons under Muzan Kibutsuji's command. These demons are immensely strong, with unique and devastating abilities. Most of them hold their positions for long periods, demonstrating their resilience and ability to survive the challenges imposed by Muzan.

Gyutaro and Daki are two demons who share the position of Upper Moon Six in the Twelve Kizuki in Demon Slayer: Kimetsu no Yaiba. Gyutaro is the older brother and, despite sharing the position with Daki, is considered the true holder of the position by Muzan Kibutsuji. They are notable for possessing a single body, with Gyutaro usually residing within Daki.
