ユベール

He is a prime minister who is resourceful and proficient at schemes. He is also 27 years old (age of his outward appearance) and known as the walking dictionary in Parterdeame. Being in charge of the heroine's lessons, he exists closely as an older brother figure. He is basically sweet towards the heroine but he is strict when he treats her as the Reine. He is not the type to mix business with personal matters.

His mansion has calm colors and scores perfect in conveying an adult-like feeling for an intellectual like him. The lights produce a subdued Japanese taste.
