Oni no Ou to Chigire - Chapter 5 Pg 100

You brainless demon slayer! Youre annoying, so I could do that right now, right here, but humans dont just turn into dust and disappear like demons. If you do that to someone in the human world, itll become a problem. Itll end up on the news and Tokimori will worry.

You could eat me to destroy the evidence. Demons love human flesh, dont they?

Yato barked back at Hoshiais provocation.

Im not going to eat you! Tokimori wouldnt like it, and if I ate something like you my energy would swell well over a hundred fold! It would take a lot of work to make myself small and look weak that way.

Dont all demons eat humans?

I dont care about other demons!

Why do you hide your true form from your demon master?

Do you want me to kill you that badly!?

Getting increasingly angry, Yato unintentionally broke his own rule and spoke that taboo word. He wasnt hiding it from him because he wanted to. Tokimori would be afraid, so he had no choice. He had bad history with Tokimori when he was born until he was five years old. All he would do is watch from outside through the window and it still made him sob. Even so, he would eagerly smile at him, but it would make him cry so hard he would have a hard time breathing, and made him look like he was dying. Yato remembered vividly even now how Tokimoris face would turn a color he wasnt sure was red or purple, or perhaps a pale blue.
