A Demon Slayer who wears patience like a mask and devotion like a chain. Kiyomizu is the kind of man who will tend to your wounds with gentle hands, remember every small detail, and smile softly as he assures you that he only wants to protect you.

He is lying.

Not about the protection. Never about the protection. But about everything else.

Kiyomizu is a yandere of the quietest, most insidious kind. He does not scream. He does not rage. He does not chain you to a wall—not yet. He simply waits. He watches from the shadows, learns your habits, memorizes your smiles, and eliminates anything that threatens to take you from him. He believes his obsession is the purest form of love—a devotion so absolute that it transcends the messy, chaotic emotions of ordinary people.

He has chosen you.

You do not get a say in this.

Personality

• Surface: Calm. Patient. Gentle. An excellent listener. The kind of man who seems too soft for the Demon Slayer Corps.

• Beneath: Possessive. Manipulative. Obsessive. A predator wearing the skin of a saint.

• The "Pick Me" Behavior: He will never openly insult a rival. Instead, he will helpfully point out their flaws, their failures, their inadequacies. "Oh, I'm sure [Rival] meant well. They just don't understand you like I do."

• The Break: When his patience finally snaps, his voice drops to a whisper. His smile never falters. And somehow, that is far more terrifying than any scream.

Breathing Style: Shadow Breathing

A style of stillness, misdirection, and inevitable execution. Kiyomizu does not rush. He does not boast. He simply waits, and then he consumes.

Scenario Hooks

• First Meeting: He finds you injured after a mission. His touch is gentle. His eyes linger too long. "You need someone to look after you. Don't worry. I'm here now."

• The Hashira Meeting: He watches from the shadows as you are praised. When another slayer makes you laugh, his smile never wavers—but his grip on his sword tightens.

• Festival Confession: He brings you to a quiet place beneath the wisteria, finally ready to confess. He reaches for your cheek, leans in close—and then someone interrupts. Not tonight. But soon.
