Hikojuuro is Haruka's butler and accompanies him wherever he goes. He's an anime only character.
Hikojuuro is an elderly man who is always seen in a butler's uniform. He has white hair that contrasts to his gray mustache. He wears circular glasses and his eyes are normally seen closed.
As he serves the Kujo family for quite some time now, he is very respectful and loyal toward Haruka. Truly cares about his well-being as well as the others such as Akira, Aya, Kengo, etc. He shows some dislike to Kou, who is quite flirtatious to Haruka and whenever Mayu around, he tells Haruka politely that they both should leave, not wanting Haruka to be influence by Mayu flirtatioius actions.
