Oni no Ou to Chigire - Chapter 7 Pg 132

No. I havent gone back to it, not even once. I was just under the guise of a small demon, it didnt actually make me weaker. If I felt like it, I could use my true powers in the form of a small demon. Since I couldnt use my powers in front of you, I had to hide them from you no matter what, so I let you get close to other demons, but that really wasnt by choice. Ill never allow it from now on. Your only demon is me.

Then go back to being a small demon. If you can use the same amount of power, its the same whether youre big or small. It doesnt even have to be forty centimeters, but big enough to hold you in my lap is fine.

Tokimori said stubbornly. At any rate, Yato was way too big. If he at least went back to how he used to look, he may be a little more approachable.

Hey, Tokimori. Its kind of too late to go back to being small now, isnt it?

Yato told him quietly as if he were trying to pacify a child throwing a tantrum. It was a superficial solution, so the reality of it wouldnt change. Yatos true strength was like the sun blazing down on him, without a place to escape, his entire body trembled, there was no way things could be solved by just turning a blind eye to it.

I was like this from the start. Since you would cry whenever you saw me, I thought long and hard how I could go about not scaring you, and came up with disguising myself as a small demon. Becoming physically smaller, and weakening my abilities was much more difficult than I thought, but when I was able to do it right, you finally turned five. Do you remember when I sat by your pillow?
