Cornelius

Cornelius (コルネリウス Koruneriusu) is Rozemyne's older brother and the third son of Elvira and Karstedt. He is an apprentice knight who is assigned to Rozemyne once she is adopted by Sylvester. Like Angelica, he only guards her while she is in the Aub's Castle as they have not yet come of age.

He is friendly with Rozemyne, impressed with her ability and dedication to learn how to become a proper noble. Seeing Rozemyne's efforts he is motivated himself to gives his best.

When Rozemyne moves into Karstedt's estate, he is quick to push her into taking over his role of emotional support for his mother, Elvira, as they are both fellow females. When Elvira told Cornelius about Rozemyne, he feared that the same quarrels from when Rozemary was still alive would destroy the family again.

He tries to bond with Rozemyne and asks Ferdinand what he could give to Rozemyne. As Rozemyne is only interested in books, they make a field trip to the estate's book room. Cornelius unaware of Rozemyne's poor health, was taught the cruel way that Rozemyne would immediately faint. Without even reaching their destination Rozemyne faints. After learning about Rozemyne's poor health, he talks to Ferdinand about it. They set up a trap for Wilfried to teach him to be careful with Rozemyne. This does leave Rozemyne unconscious and blood-covered but she is healed by Ferdinand. This is done before her guardian knights officially their duty so that they wouldn't be held responsible for Rozemyne's wounds.

Due to Rozemyne's influence he starts to take his studies more seriously, as he is impressed with what she does and what she can do even with her lack of health. He becomes part of the study group for Angelica with Damuel and Brigitte, to help her pass, as she was failing her knights course. Rozemyne used one of her desert recipes to convince him to help her study.

His mother Elvira continues to see Cornelius improve at school as well as his knight training. He becomes a good student compared to the lazy attitude he use to have before Rozemyne. Cornelius also becomes very fond of the new food that has been introduced to him by Rozemyne, especially the deserts. For the opening of the new Italian Restaurant, he volunteers to go as a guard so he is able to eat the new food.

Cornelius helps defend Rozemyne during the kidnapping of Charlotte. When the kidnapper threw Charlotte away in mid-air, it was Cornelius who saved her from falling to her death. Unfortunately while he returned Charlotte to the castle at Rozemyne's own insistance, Rozemyne was captured by a second assailant and poisoned, before Cornelius could return to help. Before Ferdinand took her to the temple to heal her, Cornelius was able to return his sister's highbeast feystone to her, which he found while trying to track down the culprint. During the time Rozemyne is asleep he is trained by Bonifatius, his grandfather in body strengthing technique as well as knight training.

Spoiler for Part 4 Volume 2 He becames Rozemyne head knight with Damuel after she wakes up and is in charge of her security at the Royal Academy. His growth as a knight can be seen during the ditter with Dunkelfelger where his leadership and high mana capacity can be seen.

Cornelius and Rozemyne grow closer as "brother and sister" during the time at the Royal Academy. One of the reasons is that adults are not around and they interact in a less formal manner in the Ehrenfest Dormitory. Fellow Attendants to Rozemyne notice how they interact and make the comment about how close they are. Cornelius handled the rostering the knights to guard Rozemyne while also making sure they were still able to do their studies. He also managed Angelica's study while also guarding Rozemyne himself, he asked Rozemyne if she could go to the library every other day so it would be easier for him. Rozemyne refused, and she said she had complete confidence for to be able to do both.


 * Cornelius has four elemens: Light, Water, Fire and Wind.
 * Like his father, his highbeast has the shape of a winged wolf.
 * Learning the Rozemyne Mana Compression Technique has increased his already large mana capacity even further. At his own estimation he has already surpassed his father despite only being 14 and thus not yet at the end of his growth period.
