Oni no Ou to Chigire - Chapter 2 Pg 55

Yato?

Yeah!

He answered full of energy, smiling widely. The white fangs peeking out of his mouth were as puny as his horns. They didnt look like they would hurt even if they bit him. The stray cat his grandparents would chase out of the garden had much sharper and longer fangs.

Are you going to eat me, Yato?

Due to Katsumotos special lessons, and the encouragement of his usual cowardly and cautious personality, that was the most important thing Tokimori wanted to confirm for now.

Im not going to eat you.

Really? You wont eat anyone else either?

Yeah, I wont eat you or anyone else.

Can you pinky swear?

I can.

Yato held out his arm toward Tokimori and offered his pinky.

I pinky swear, if I lie, Ill swallow a thousand needles.

Unable to actually hook their pinkies together, they both held out their pinkies and recited the pinky swear together. Tokimori finally relaxed.
