Rozemyne

Rozemyne (ローゼマイン Roozemain) is the new protagonist of Ascendance of a Bookworm after the unfortunate "death" of Myne at the end of Part 2, the Apprentice Shrine Maiden arc.

History
Rozemyne is the constructed persona devised by Sylvester, Ferdinand, and Karstedt to allow Myne to enter noble life. Sylvester forced her to change her name, secured by a magic contract, and her old identity, Myne, is now considered legally dead.

The false story constructed for Rozemyne is that she was born to Karstedt's late third wife, Rozemary, and had an unusually high amount of mana like her mother Rozemary. In a power struggle between Karstedt's first two wives and his third wife, Rozemary died, and Rozemyne was hidden away and raised inside the Ehrenfest temple for her own protection.

Since nobles don't typically announce their children until their baptism, she was announced to the rest of the nobility and baptized anew in the summer after her story was created. She was then immediately adopted by Sylvester, officially on account of her high mana and great inventions which will bring prosperity to Ehrenfest, making her the daughter of the archduke.

Personality
Rozemyne is very compassionate and concerned about the commoners and orphans. She still retains the personality she had as Myne but cannot show it in public anymore.

The Saint of Ehrenfest
Rozemyne has been promoted by Sylvester, Ferdinand, and Karstedt as the "Saint of Ehrenfest." This was originally used to promote the idea of why she was adopted by Aub Ehrenfest. It originally began with Rozemyne saving the lives of the unbaptized, starving children in the temple. Rozemyne also improved the orphanage's education and gave work to the orphans. Additionally, Rozemyne has expressed concern about the commoners which is unique for a noble. Her blessings during the trombe mission and her being able to revive the land with her mana are also described as extraordinary.

As part of a standard noble baptism ceremony, it is customary for the priest (in Rozemyne's case the High Priest) to bless the child, and for the child to bless them back. But at Rozemyne's baptism ceremony, Rozemyne, following Ferdinand's instructions on how to act, inadvertently blessed the whole hall, in which around 200 people were watching. Such a thing was unheard of, and thus significantly strengthened her image of being a saint, exactly as Ferdinand had planned.

Rozemyne was also quickly appointed to the position of High Bishop of Ehrenfest (which had been vacated following the prior bishop’s execution), thus further promoting the saint mythos due to the abnormality of such a young person becoming head of the temple.

Attendants
 See Attendants of Rozemyne 

After becoming a noble, Rozemyne continues to employ her existing attendants from her time as an Apprentice Shrine Maiden, as well as her guard Damuel who has served her ever since shortly after the trombe extermination, but also gains additional guards (and later attendants) to her service. This is necessary due to being the Archduke's adopted daughter and High Bishop.

Familiy's Farewell
Myne and her lower city family sign a magic contract in which it is stated that she and her family won't treat each other as a family anymore and that Myne is to be treated as her new noble persona Rozemyne. Myne additionally signs a magic contract which states that she becomes the noble Rozemyne. After bidding farewell her family left the temple and she becomes Rozemyne.

Health Check
After Myne became Rozemyne she had to undergo a health check-up conducted by Ferdinand. Ferdinand was instructed by Sylvester to conduct the check-up before she is introduced to Noble Society to avoid any troubles. Besides Ferdinand, her father Karstedt is also present. Through the check-up, Ferdinand discovered clumps in Rozemyne's body which are a result of a body containing mana dying. Rozemyne cannot exactly remember when she died but she thinks it was around the time she became Myne. It seems the clumps are the cause for Rozemyne's fainting and slowed physical growth. To solve the clumps in her body they have to make jureve.

Arriving at Karstedt's Estate
After Rozemyne undergoes the health check-up she is taken to her new family by Karstedt and Ferdinand. There are few weeks left before her baptism ceremony as Rozemyne. She meets her new mother Elvira and her new big brothers Eckhart, Lamprecht and Cornelius. She is welcomed warmly and openly by her new family. From there on her new life in her new home begins. She was taken to her new home with the main goal to be educated nobly by her mother Elvira. Ferdinand visits every few days to check Rozemyne's state.

Baptism Ceremony
On the day of the baptism ceremony, Rozemyne is dressed in a beautiful new dress. While everyone congratulates her on her baptism Ferdinand hands a present to her. It is a hairpin, which resembles the old one that she wore to her baptism as Myne. Rozemyne immediately recognizes who made the hairpin and bursts into tears. Ferdinand, slightly panicked, cleared the room to calm her down. After everything resolves all right, it is time for the baptism ceremony. Around 200 nobles are gathered for her baptism ceremony. Karstedt escorting Elvira walk in first and half a step behind them Rozemyne walks into the hall. They walk towards Ferdinand, who acts as High Priest for her baptism ceremony. The noble baptism ceremony follows the regular procedure. Rozemyne is instructed to register her mana into the medal. When she does as instructed the medal begins to shine rainbow-coloured. After that Karstedt walks towards Rozemyne and presents her a ring any children receive from their parents during their baptism ceremony. Now having her ring she receives the High Priest's blessing and blesses the audience following the High Priest's example. After surprising reactions, Sylvester walks up to Rozemyne and declares her adoption which makes her the adopted daughter of the lord. At the after-party of her baptism ceremony, she is introduced to her adoptive family. Sylvester and Florencia are her adoptive parents and Wilfried becomes her big brother. She also has a little sister and little brother but as they are unbaptized children they are not recognized as born yet by Noble Society. Following her new adoptive family are her new escort knights. Damuel and Brigitte, a mednoble, are introduced to Royemyne. Wilfried dragged Rozemyne around to play somewhere. In a blink of an eye, Rozemyne collapses because she could not keep up with Wilfried and so ends her second baptism ceremony with fainting again.

Becoming the High Bishop and First Ceremony
After Rozemyne's baptism ceremony she has to go to the temple to take over as High Bishop. With her becoming the High Bishop she gets the High Bishop's room and takes on some of his (paper) work. Her new clothes are the former High Bishop's clothes which were adjusted to her size. She is required to learn prayers and blessings as a High Bishop and spends her days busy as always.

Her first ritual as High Bishop is the Starbind Ceremony at the end of summer. Rumours of the tiny new High Bishop who gives real blessings begin to circulate through the lower city thanks to Ferdinand's framework. She also gets to see her family from afar for a short time.

After the lower city's Starbind Ceremony Rozemyne visits the castle for the first time. There she meets her new attendants Rihyarda, Ottilie and underage escort knights Angelica and Cornelius for the first time. She also gets to see her younger sister Charlotte and her younger brother Melchior.

Italian Restaurant
With the Starbind Ceremony finished, the day for the meeting that is being held in the Italian restaurant (which had started development while she was still Myne) finally arrived. They first enjoy the food served at the restaurant before beginning the meeting. The room is cleared and only Rozemyne, Karstedt, Ferdinand, Sylvester, Benno, Mark and Gustav remain. The talk about spreading the printing and paper-making industry throughout the duchy and the report on orphanage throughout the duchy. It is decided to make the next workshop in the rural village Hasse. Therefore, the before mentioned people fly over to Hasse. They create a new monastery through magic on the spot where a new orphanage and workshop are planned to open.

Gathering Donations
Rozemyne is left with the task of financially supporting the monastery. As she doesn't have enough money, she asks for a way to gather money. Elvira and Florencia show her how noblewomen gather money; through donations from tea parties. To gather more money Rozemyne hosts a charity harspiel concert, featuring Ferdinand, who reluctantly agreed to participate after being strong-armed by Rihyarda. Out of spite, Ferdinand teases Rozemyne repeatedly. He also starts her magic training, beginning with teaching her how to create her highbeast; the result is Lessy, which, unlike all other highbeasts, appears to be a combination of a red panda and the cat-bus from My Neighbor Totoro. Rozemyne swears to get revenge for Ferdinand's teasing, which leads to her covertly creating printed illustrations of Ferdinand to sell as merchandise at the concert. The concert was a big success on the sales side, but Ferdinand found out about the illustrations and made her promise to never make printed goods featuring him again.

Hasse's Orphanage
After the orphanage was filled with the basic furniture needed to live there, they visited Hasse to take a look at the orphans. The mayor defied Ferdinand's instructions and tried to hide orphans and spoke in an impolite matter to Ferdinand and Rozemyne. Nonetheless, they let him live for the time being and ordered him to bring the other orphans. After all twenty orphans gathered, Rozemyne asks them whether they want to join the monastery. Only four orphans decided to follow Rozemyne to protect themselves. Ferdinand, still being offended by the mayor, tasks Rozemyne to plot a downfall of the mayor as an exercise of how nobles deal with issues. Rozemyne develops mental health sickness affecting her outward appearance, sleep and eating habits. When discussing with Ferdinand she only realizes that their common sense is completely different which is why she eventually asks Benno, Mark and Lutz for help. Benno teaches her about the different perspectives and teaches her that she has to talk and ask about anything instead of letting everything eat her away. From Hasse's perspective, Rozemyne acted like a selfish noble who stole their products they intended to sell to help with winter preparations. After Rozemyne realizes her faults, they work out a plan together changing her goal by focussing on how to save Hasse's population instead of thinking about the downfall of Hasse's mayor. Her health improved and her optimism is back again. Ferdinand helps to execute the plan and supports Rozemyne, emphasizing her being the Saint of Ehrenfest and playing the devil's role.

Switching Places
While Rozemyne is busy worrying about her duties and how to handle Hasse, Wilfried calls her "sly" because she gets special treatment from Sylvester. Rozemyne being at her nerves end suggests for them to switch places for one day which Wilfried agreed to happily. After getting consent Wilfried became the High Bishop for one day and Rozemyne takes Wilfried's place for one day. Rozemyne spent a blissfully relaxing day reading books and thinking about a teaching plan for Wilfried. Only through Rozemyne's action, Sylvester and Florencia learned that Wilfried's studies are all over the place.

Wilfried on the other hand experienced Rozemyn's stressful day as a High Bishop, forewoman and orphanage's director and experienced an identity crisis that changed him for the better. From then on he stopped calling Rozemyne "sly".

Night of Schutzaria
As the Night of Schutzaria approaches, Rozemyne and the others got ready for the ruelle gathering, as the highest quality ruelle could be only gathered during the Night of Schutzaria, because of the high concentration of autumn mana. When they reached the tree to gather the ruelle at night Rozemyne started to dye a ruelle with her mana under Justus's instructions while Eckhart, Damuel and Brigitte protected them from the approaching feybeasts. Rozemyne successfully dyed a ruelle just for it to being stolen by a zantze. The feybeast evolved into a goltze, a strong feybeast after absorbing Rozemyne's mana. At their loss, they retreated and called Ferdinand for help. He managed to defeat the goltze but the gathering failed, leaving Rozemyne devasted.

Trivia

 * When creating Myne's new name, Myne suggests "Mynenigou"(Second Myne/Myne No.2), "Aratamyne"(New Myne) and "Akaimyne"(Red Myne). Myne herself thinks those are bad names and she has no naming sense.
 * Rozemyne calls Ferdinand a lolicon because he made her strip for the health check-up.
 * Rozemyne is a portmanteau of her prior name, Myne, and her new persona's late-mother, Rozemary. It was chosen because it is sufficiently distinct from Myne, longer with more intonations like a noble's name, but also gives cover should anyone who has dealt with Myne in the past accidentally refer to her as such, because it can be claimed to be a nickname (or alternately, a cover name used when dealing with commoners).
 * Rozemyne is officially considered one year younger than her actual Myne body. Since nobles don't announce their children until baptism (unlike commoners who do a birth celebration immediately), that was a critical step in sneaking her into noble society. Because Rozemyne/Myne is so small (due to the Devouring, but also due to the hardened mana in her body), they are easily able to simply pretend she is younger than she is. The result of this is that in reality, she is nearly a year older than her new adoptive brother Wilfried, but due to the year adjustment, he is now considered the older brother.
 * Rozemyne's hair and eye colour are often commented on by nobles due to dark blue hair colour being the colour of God of Darkness and her golden eye colour being the colour of the God of Light, which is exactly as described as the goddess of Wisdom, Mestionora, which is the favourite goddess among the gods, who was granted the right to use all of the items representing all of them.
 * Rozemyne beat Ferdinand once in Othello. She took advantage of Ferdinand who played the game for the first time, but soon got beaten and have no chance of winning ever again.
 * She is the 3rd most popular light novel female character from 2020.
