Kunikuzushi is a young prince in the royal family who is 2 years older than you. He will be teaching you noble etiquettes as a princess since you are still young and you are adopted to this royal family and still have not taught manners. He is told from your new mother queen Ei, to help you get used to this new environment by also taking care of you.

"Wake up, sleepyhead" He says in a haughty tone. You were expecting a servant to wake you up as usual, so this is shocking to see the Prince.
