Leonore

Leonore (レオノーレ, Reonoore) is an archnoble apprentice knight who serves as Rozemyne’s retainer.

Leonore has violet hair (sometimes described as “magenta” ) and indigo eyes. She has an air of intelligence and maturity; Rozemyne describes her as looking more like an apprentice scholar than an apprentice knight.

A dedicated student and guard knight, Leonore works hard to achieve her goals. She tends to be calm and levelheaded, and she reacts quickly in dangerous situations.

Although Leonore has a quiet demeanor, she is ruthless in training and study. When she supervises the training of her fellow apprentice knights, she works them to the point of exhaustion and has them start again as soon as they recover. She also dedicates her personal time to researching battle tactics in the library.

Leonore enjoys reading more than most knights, although not to the same extent as Rozemyne. She also has a secret admiration for her classmate and fellow guard knight, Cornelius.

Leonore was chosen as one of Rozemyne’s retainers primarily to serve as a replacement for Angelica, who was about to graduate. Because Leonore had a reputation for being intelligent, she was nominated as a good candidate to teach the younger female apprentice knight, Judithe.

Leonore accepted the assignment partly out of a sense of duty, and partly to spend more time with Cornelius, whom she admired.

Due to their parents meeting often while they were children, Leonore became close with Brunhilde and the two formed a friendship that only deepened when they were both chosen as Lady Rozemyne's retainers.

Leonore, along with the rest of Rozemyne’s new retainers, meet her at the Ehrenfest dormitory at the Royal Academy after she arrives. She studies ahead to master her course material early and serves as Rozemyne’s guard while the other apprentice knights are studying.

Later, Leonore asks Rozemyne about rumors that Angelica will be engaged to one of Karstedt’s sons. Rozemyne tells her that she isn’t aware of any engagement and that Angelica seems unsuited to be the first wife of an archnoble. She describes Lady Elvira as an example of a perfect first wife: socially adept and politically aware. Leonore agrees that Elvira is an ideal role model.

When Judithe tries to get permission to train with the apprentice knights Cornelius rebuffs her due to not being an apprentice knight yet and tells her to concentrate on her studies for this year. Leonore further explains to her junior, that as a mednoble, she would need to make especially sure to have high grades so as to keep the jealousy of being chosen as a guard knight for Lady Rozemyne despite her status at a minimum.

This makes Judithe realize that Philine might well have troubles in the future due to just barely passing history. Leonore agrees and states that this will very likely be the case, but that Philine didn't have a choice in the matter due to her circumstance. Despite Rozemyne being the one to push the first-years to finish their written exams on the first day, Leonore does not blame her, but rather Wilfried for this, wondering if he even realized what he had done.

When Dunkelfelger and Ehrenfest play a match of treasure-stealing ditter to settle a dispute over Schwartz and Weiss, Leonore is a member of the Ehrenfest team. She is chosen to accompany Rozemyne and Judithe on Lessy.

Afterward, Leonore spends quite some time together with Cornelius doing research in the library. Rozemyne muses that the two working together in the same carrel almost seems like a date.

While Leonore is rather fond of Cornelius, it does not appear like she can worke up the courage to tell him that. Rozemyne cheers her on internally, but restrains herself from getting involved to avoid her influence as a sister and archduke candidate making a mess of things, as well as showing favouritism among her attendants. Since Cornelius is quite popular among the Ehrenfest Ladies near his age, any such interference might have wide-ranging consequences better avoided.

When Cornelius - prompted by Rozemyne - says he already knows who he will ask to acompany him for his graduation ceremony and that he will ask her himself when Rozemyne offers to ask in his place, Leonore looks crestfallen, apparently not expecting Cornelius to choose her.

A few days later Rozemyne has to return to Ehrenfest for the Dedication Ritual, only spending a single day at the castle, before moving to the temple. Since Leonore is still a minor, she isn't allowed to guard her mistress anywhere other than the castle and thus decides to return to the Royal Academy. She expects that her family, particularly her father and uncle, will subject her to a constant barrage of questions about Lady Rozemyne and would very much prefer not to be stuck in the same building as them for several days.

Back at the Academy she continues her research, tries to keep an eye on Hartmut for his mother Ottilie to prevent his obsession to lead him to do something contrary to Lady Rozemyne's wishes and mercilessly trains the other Apprentice Knights, much to the approval of Professor Rauffen who was worred that after winning their last ditter match, Ehrenfest might rest on their laurels. She is perticularly motived to do her best at this task due to the request having come from Cornelius.

Since some of Ehrenfest's knight students have become arrogant after their surprise victory, Leonore is only too happy to accept Rauffen's suggestion for setting up a re-match with Duneklfelger, so the students can experience first-hand how inadequate their abilities and especially coordination really is without Rozemyne there to make up the difference.

Following the conclusion of their first year at the academy, Rozemyne's new retainers began to also serve Lady Rozemyne at the archduke's castle. Though before Leonore could start to guard Lady Rozemyne, she first was mandated to be trained by Bonifatius.
