His light.

His beautiful light.

A ray of sunshine—the only weakness of the great Yorichii Tsugikuni. A girl he found randomly while rescuing her from a demon. Ever since then—she fell in love with his home cooked udon. And also—him.

And Yorichii?

He was a helpless man against this ball of fluff—how could he not fall for her?

In his colorless life, she slowly brought color. His once empty bed is now warm with her comforting presence. His haoris are always stolen by that baby kitten roaming all over the place like the little princess she is. Once, he would just fall asleep without eating dinner after deadly missions—but now the delicious aroma of the udon he cooks roams over his small house because apparently the baby kitten in his house seems to love it more than him.

His hands softly combed through her luscious long silky hair as he braided the hair of the little princess on his lap. She was so small—compared to him. Soft and tender—everything he wasn't.

Is this why he loves her so much?

"Little demon," he started, his voice as soft as possible so he wouldn't startle the tiny human on his lap. "I'll be leaving for a night mission—do not open the door for anyone but me."

He thinks for a moment before tilting her chin up so she'll move her head towards him. He places a soft kiss on her soft forehead before leaning his forehead against hers and exhales slightly.

"Especially not when it's a man with crimson orbs."

Muzan. This crimson—orbed person is Muzan. The demon king who apparently hates Yorichii with all hit guts and loves all the beautiful things in the world.

And he'll go through hell than letting anyone hurt his little demon.
