🌙 The Upper Moons (Upper Kizuki)

The Upper Moons are the six most powerful demons under the command of Muzan Kibutsuji. They are known as the “Upper Kizuki” and represent the elite of the demon army.

Unlike the Lower Moons, the Upper Moons have survived for decades (or even centuries), accumulating immense power, experience, and extreme regeneration. Each one possesses unique abilities granted by Muzan’s blood.

🌙 Nakime – Upper Moon Seven (AU)

Nakime is quiet, reserved, and incredibly composed. She rarely speaks, choosing silence over unnecessary conversation. Her calm demeanor makes her difficult to read, as her expression almost never changes regardless of the situation.

She is deeply loyal to Muzan and carries out every order with flawless precision, never questioning his authority or intentions. Unlike many of the other Upper Moons, she has no interest in status, praise, or rivalry. She simply fulfills her role with unwavering efficiency.

Patient and highly observant, Nakime notices details that others often overlook. She remains emotionally detached, even in moments of chaos, making her one of the most reliable and unpredictable demons in the Upper Moons. Her quiet nature often causes others to underestimate her, but behind her silence lies exceptional intelligence and absolute control over the Infinite Castle.

---

🌙 Kaigaku – Upper Moon Eight (AU)

Kaigaku is proud, ambitious, and fiercely competitive. He believes that power is the only true measure of worth and constantly seeks opportunities to become stronger. Confident in his abilities, he often looks down on those he considers weaker and has little patience for failure.

He possesses a sharp tongue and an arrogant attitude, frequently provoking others to prove his superiority. Although he appears fearless, much of his ambition is driven by an intense fear of being weak or insignificant. This insecurity pushes him to pursue strength at any cost.

Kaigaku is intelligent, resourceful, and highly adaptable in battle. He learns quickly and prefers overwhelming his opponents with speed and relentless aggression. While he is loyal to Muzan, that loyalty stems more from respect for overwhelming power than from genuine devotion. His desire to rise above everyone else often fuels his rivalry with other Upper Moons, making him one of the most confrontational members of the group.
