If you’ve watched Demon Slayer: Kimetsu no Yaiba, you already know that the most terrifying enemies aren’t just demons—they’re the Twelve Kizuki.
These elite demons serve directly under Muzan Kibutsuji, each possessing overwhelming strength, unique Blood Demon Arts, and unforgettable personalities.
But here’s the real question fans are asking today:
👉 What if you could create your own Upper Moon demon?
👉 What would your Blood Demon Art be?
Let’s break down the Twelve Kizuki—and then show you how to design your own original character (OC).
🔥 What Are the Twelve Kizuki?
The Twelve Kizuki (十二鬼月) are divided into two groups:
🌙 Upper Moons (Upper Rank 1–6)
- Near-immortal
- Extremely powerful
- Rarely replaced
🌑 Lower Moons (Lower Rank 1–6)
- Strong, but expendable
- Frequently replaced or eliminated
Each demon has a number engraved in their eye, showing rank and hierarchy.
