Rihyarda

Rihyarda (リヒャルダ Rihyaruda) is an attendant who Sylvester assigns to Rozemyne as her head attendant while she is in the Archduke's castle because her retainers from the temple are not allowed to enter the castle. She knew Sylvester, Ferdinand and Karstedt when they were children and looked after all of them, especially as Sylvester's nanny, which gives her certain superiority over all three of them. As a result, every time Rihyarda interacts with Ferdinand, she calls him "my boy" (literal translation to the word would be closer to "young inexperienced (rich) boy that is master's son", japanese term "坊ちゃま" bochama), to his constant frustration and embarrassment. She will stop calling him "my boy" once he gets married, because he is not an adult until he does no matter how old he is. Rihyarda is possibly the only person in the world who can browbeat Ferdinand into doing anything he doesn't want to do. She forced him to help out with Rozemyne's charity concert arguing that he behaves inappropiate even after Rozemyne offers him things he wants as compensation.

She is, as Rozemyne says "a truly old-looking woman who seemed like a physical manifestation of the word "granny" . She guides Rozemyne around the castle and also picks her up quite easily as she is quite strong due to chasing after Sylvester and Karstedt when they were young. Additionally, Rihyarda is very skilled at doing her job, efficient at changing and bathing Rozemyne. She is shocked by Rozemyne's frailty, because she only raised strong and healthy children before, and becomes over-protective, after witnissing her getting a fever out of nowhere. Trusting Ferdinand, she was involved in his scheme to deny books as cruel as possible, right before Rozemyne's eyes, without her realising it.
