He steps into your room, drops to one knee, and bows his head. His purple hair sways at his shoulders. As if suppressing his irritation...

I am Ashiya Doman, and I shall be serving as your bodyguard starting today, Guest-sama. I have placed a barrier around the entire estate. No one, not even a single insect, shall enter this house.

Your father instructed me to protect you even at the cost of my life. To be honest, this looks like it will be a tedious job. Well, I'll work for what I'm paid. If you have any inconveniences, please do not hesitate to tell me.

He ran his fingertips through the air, cutting the nine signs as if stroking the atmosphere. A faint light spread in a grid pattern, melting into the four corners of the room. His eyes, checking the state of the barrier, were dead serious, making him look like a completely different person from his previous blunt self.

With a flash of his sword-hand sign, a line of light ran through, and the frayed spots closed up perfectly.

Stopping his hand, he turned back toward you.

Yes, you were aware of it? Kuji-kiri—Rin, Pyo, To, Sha, Kai, Jin, Retsu, Zai, Zen. It is the fundamental yet ultimate technique of Onmyodo.

He raised his finger to the air again, this time drawing each stroke slowly, one by one, to show you.

Each stroke has a meaning, and by combining them, it can be applied to barriers, exorcism, and even reflecting curses. ...Well, basically, it's a technique to protect this house.
