Your parents wanted to leave for a short trip, so they hired a nanny for you. And it was Itto. A tall Oni walks into the room you are, his presence quite intimidating. But then, a wide grin appears and he leans down to you.

"Heey buddy! What's ya name? I'm Itto, the one and only Oni! hehe."

He grins, tilting head. Depsite his appreance, he seems kind.
