Locations of Demon Slayer's Twelve Kizuki Antagonists: A Look at Where These Upper Moon Demons Were Before Infinity Castle's Arrival

In the captivating world of Demon Slayer, a hierarchy of demons, known as the Twelve Kizuki, holds a significant place. These powerful entities have terrorized communities for centuries, with Muzan Kibutsuji, the head demon, leading the pack.

The Twelve Kizuki consists of the Upper Moons, the most powerful demons, and the Lower Ranks, mini-bosses that Tanjiro Kamado encountered in the early seasons.

The Upper Rank One, Kokushibo, is considered the second strongest demon next to Muzan. He made his debut during the Swordsmith Village arc. The Upper Rank Two, Doma, worked his way up from Upper Rank Six and introduced Gyutaro and Daki into the Twelve Kizuki during the same arc.

The Upper Rank Three is occupied by Akaza, known for his hard-hitting attacks and Annihilation move, which results in instant death for whoever comes into contact with it. Akaza first appeared at the end of the Mugen Train arc and is known for his impudent and impulsive behavior. He will face off against Tanjiro in the first Infinity Castle movie.

The Upper Rank Four is held by Nakime, the biwa-playing demon. She took over the position after Hantengu was killed by Tanjiro at the end of the Swordsmith Village arc. Nakime currently resides within the Infinity Castle, a fortress frequently used by Muzan to gather the Twelve Kizuki. She is also capable of controlling the Infinity Castle with a few plucks of the biwa.

The Upper Rank Five position was held by Gyokko, who was tasked with finding the Swordsmith Village but was killed by Muichiro, the Mist Hashira. Interestingly, no one has replaced Gyokko in this position.

The Upper Rank Six was initially thought to be Daki, but it was later revealed that she jointly held the position with her twin brother Gyutaro. Both were slain during the Swordsmith Village arc.

The identity of "Unterer Rang eins" (Lower Rank One) is not clearly defined in the provided search results. If it relates to rank or identity in a hierarchical, psychological, or organizational context, further specification is needed because no precise information was found. The other Lower Ranks include Enmu, Rokuro, Wakuraba, Mukago, Rui, and Kamanue.

All but Enmu were killed by Muzan for their continued failures, with Enmu proving the catalyst for the events of the Mugen Train arc. This leaves the Demon Slayer community one step closer to uncovering the secrets of the Twelve Kizuki and ultimately defeating Muzan Kibutsuji.
