Ascendance of a Bookworm: Adopted Daughter of an Archduke has released its third main promotional trailer ahead of the anime’s second cour, which begins airing in Japan on July 11, 2026.
The new video combines previously unseen footage from the continuation with both of its new theme songs. Kana Nishino performs the opening theme “Power of Love,” while adieu, the musical project of actress and singer Moka Kamishiraishi, provides the ending theme “Wanna me.”
Cour 2 will continue Rozemyne’s life as the adopted daughter of Ehrenfest’s archduke, expanding the political, magical and economic challenges that began during the first half of the season.
Although her identity and social position have changed, Rozemyne remains determined to establish a sustainable printing industry and make books available to far more people. The new trailer makes it clear that this ambition will place her inside increasingly dangerous conflicts involving noble society, powerful magic and the responsibilities attached to her new family.
Ascendance of a Bookworm Cour 2 Begins on July 11
The second cour will begin its Japanese television broadcast on Saturday, July 11, 2026.
New episodes will continue airing through the nationwide Yomiuri TV and Nippon TV network on Saturdays at 5:30 p.m. JST, except in certain regions. TOKYO MX will also continue broadcasting the series on Monday evenings.
- Cour 2 premiere: July 11, 2026
- Main Japanese broadcast: Yomiuri TV and Nippon TV network
- Broadcast time: Saturdays at 5:30 p.m. JST
- Additional broadcast: TOKYO MX
- International streaming: Crunchyroll
- Animation production: WIT Studio
- Opening theme: “Power of Love” by Kana Nishino
- Ending theme: “Wanna me” by adieu
The current television production began on April 4, 2026, and was announced as a two-cour adaptation. Cour 2 is therefore a continuation of the same season rather than a separately numbered sequel.
The Third Trailer Previews “Wanna me” by adieu
The newest promotional video provides the first preview of “Wanna me,” the ending theme performed by adieu.
Adieu is the musical name used by actress and singer Moka Kamishiraishi. In her message about the project, she explained that the song expresses the beauty of believing in something important.
That idea reflects Rozemyne’s journey particularly well. Her devotion to books can appear excessive or incomprehensible to the people around her, but that passion repeatedly gives her the determination to overcome illness, poverty and political restrictions.
Her beliefs also extend beyond books. Rozemyne continues trusting the value of her lower-city family, her retainers and the people helping her develop the printing industry, even when noble society expects her to prioritize status and political convenience.
The television edit of “Wanna me” is scheduled for digital release on July 11, the same day Cour 2 begins. Its digital cover uses newly created artwork from the anime.
Kana Nishino Performs “Power of Love”
Cour 2 will open with “Power of Love” by Kana Nishino.
The song was written around the idea that feelings for an important person can become a source of strength.
That theme connects directly to Rozemyne’s relationship with the people she was forced to leave behind. She accepted adoption into the archducal family to protect her parents, siblings, friends and associates in the lower city, but the separation remains emotionally painful.
Her new authority gives her more power to develop books and printing, yet it also prevents her from living openly as the daughter of Gunther and Effa.
“Power of Love” emphasizes that her affection for those people has not disappeared. It continues motivating her even when she must behave according to the expectations placed upon an archduke’s daughter.
The Trailer Highlights Family, Bookmaking and Fantasy
The third trailer is structured around three elements that remain central to Ascendance of a Bookworm: family love, book production and fantasy.
Scenes involving Rozemyne’s former family emphasize the emotional cost of becoming a noble. She can no longer approach them publicly as Myne, even though she still thinks of them as her true family.
The bookmaking footage shows her continuing to improve the technology and organization required for larger-scale printing. Producing a few handmade books was only the beginning. Rozemyne now needs trained craftspeople, reliable materials and a system capable of making books in significant quantities.
The fantasy sequences reveal a more dangerous side of her new life. The trailer includes magical confrontations, ceremonial environments and powerful abilities that place Rozemyne far beyond the relatively small-scale challenges she faced as a commoner.
Rozemyne Faces the Responsibilities of an Archduke’s Daughter
Rozemyne’s adoption gives her political protection, but it also places her inside the highest level of Ehrenfest’s noble society.
She must learn etiquette, participate in ceremonies, meet influential nobles and understand alliances that may determine the future of the duchy.
Mistakes that once affected only Myne and her immediate associates can now create consequences for the entire archducal family.
Her unusually direct personality makes this transition especially difficult. Rozemyne is highly intelligent, but she does not instinctively understand many of the customs nobles consider obvious.
She also continues treating books, craftspeople and lower-status workers as priorities in situations where other nobles would place reputation first.
Cour 2 will continue showing how she adapts to noble society without surrendering the values that shaped her previous life.
The Printing Industry Continues to Expand
Rozemyne’s ambition is no longer limited to creating a single book for herself.
She wants to establish an industry capable of reproducing written material quickly and consistently. That requires improvements to printing presses, movable type, ink, paper production and the training of new workers.
The project also creates political and economic questions. Books are rare and expensive partly because knowledge is concentrated among nobles and wealthy institutions.
Cheaper printed material could transform education, religion and commerce throughout Ehrenfest.
Rozemyne sees that transformation as an opportunity to surround herself with books. Other people may recognize that printing can redistribute information and influence, making the industry far more important than she initially understands.
Rozemyne Must Confront Her Enormous Mana
The new trailer also focuses on Rozemyne’s extraordinary magical power.
Her mana was once a life-threatening condition known as the Devouring. After entering noble society, that same power becomes one of her greatest advantages.
However, possessing enormous mana does not mean she can use it without risk. Rozemyne’s body remains physically fragile, and uncontrolled emotional reactions can produce dangerous magical consequences.
Cour 2 will place her in situations where magical ability is necessary for ceremonies, protection and combat.
The challenge is not simply learning stronger spells. She must control power that can overwhelm her body while understanding the political significance of revealing how much mana she possesses.
Ferdinand Continues Guiding Rozemyne
Ferdinand remains Rozemyne’s principal mentor in magic, noble conduct and political survival.
His strict behavior frequently frustrates her, but he understands better than almost anyone how dangerous Ehrenfest’s noble society can become.
Ferdinand knows that Rozemyne’s intelligence, mana and inventions will attract attention from people who may view her as a resource rather than a child.
He therefore trains her aggressively, attempting to prepare her for threats she may not recognize until it is too late.
Their relationship remains one of the series’ most important dynamics. Rozemyne brings chaos into Ferdinand’s carefully controlled life, while he provides the structure that allows her ambitions to survive contact with the political world.
The Archducal Family Becomes More Important
Rozemyne’s new family includes Archduke Sylvester, Florencia and Wilfried.
Sylvester’s decision to adopt her provides protection from enemies seeking to exploit her mana and inventions. It also turns her into a political member of his household.
Florencia must help Rozemyne understand the behavior expected from a noble daughter, while Wilfried becomes both a sibling and another young person affected by the responsibilities of the archducal family.
Their relationships are not purely domestic. Every interaction can influence succession, reputation and the balance among Ehrenfest’s noble factions.
Rozemyne’s presence may strengthen the family through her mana and ideas, but it can also create instability because she entered noble society with an unusual background and almost no preparation.
Rozemyne’s Lower-City Family Remains Her Emotional Foundation
Gunther, Effa, Tuuli and Kamil remain central to Rozemyne’s emotional life even when she cannot publicly acknowledge them as family.
Her separation from them was not a rejection. It was a sacrifice intended to prevent powerful nobles from targeting the people she loved.
The trailer emphasizes that distance has not weakened those feelings.
Rozemyne continues making decisions influenced by the values she learned in the lower city. She respects craftspeople because she personally worked beside them. She understands poverty because she once lived without money, medicine or books.
Those experiences distinguish her from nobles who have never needed to consider how ordinary people survive.
WIT Studio Animates the New Season
WIT Studio is producing Ascendance of a Bookworm: Adopted Daughter of an Archduke.
The change from Ajia-do Animation Works introduced a new production team and visual approach for the beginning of the third major story arc.
The latest trailer highlights detailed noble environments, magical circles, creatures and ceremonial scenes that expand the scale of the anime’s world.
The studio also gives considerable attention to smaller character expressions. That detail is essential in a society where nobles frequently hide their intentions behind polite language and controlled behavior.
Yoshiaki Iwasaki Directs the Anime
Yoshiaki Iwasaki directs the current television production.
The adaptation must balance several different kinds of storytelling, including family drama, economic development, religious duties, noble politics and magical fantasy.
Rozemyne can move from discussing printing technology to participating in a dangerous magical confrontation within the same storyline.
Maintaining a consistent emotional focus through those changes is especially important because her love of books and family connects every part of the narrative.

What Is Ascendance of a Bookworm About?
Ascendance of a Bookworm begins with Urano Motosu, a book-loving woman who dies shortly before beginning her dream career as a librarian.
She awakens in another world as Myne, the sickly young daughter of a poor soldier.
Her new society has very few books, and the volumes that do exist are far too expensive for an ordinary family.
Rather than accepting a life without reading, Myne decides to create books herself.
Her experiments begin with paper and gradually expand into ink, printing and commercial production. At the same time, she discovers that the mysterious illness weakening her body is caused by enormous magical power.
To protect her family after attracting dangerous noble attention, Myne abandons her former public identity and becomes Rozemyne, the adopted daughter of Ehrenfest’s archduke.
The Current Anime Adapts Part 3 of the Light Novels
Ascendance of a Bookworm: Adopted Daughter of an Archduke adapts the third major part of Miya Kazuki’s light novel series.
The previous anime seasons covered Myne’s childhood in the lower city and her time as a shrine maiden at the temple.
Part 3 expands the setting considerably by placing Rozemyne inside noble society and introducing responsibilities connected to the archducal family.
The production has not officially stated the exact light novel volume or chapter where Cour 2 will end.
The Franchise Has More Than 14 Million Copies in Circulation
The Ascendance of a Bookworm franchise has surpassed 14 million copies in circulation.
Miya Kazuki originally published the story online before TO Books began releasing the commercial light novel edition with illustrations by You Shiina.
The complete main novel series consists of five major parts and dozens of volumes, leaving a substantial amount of material beyond the current anime.
The franchise has also received multiple manga adaptations corresponding to different sections of Rozemyne’s journey.
What to Expect From Cour 2
Cour 2 will continue Rozemyne’s effort to establish printing while increasing the scale of the magical and political dangers surrounding her.
Her position inside the archducal family will require greater participation in noble ceremonies and social events.
Her unusual mana and inventions will attract additional attention, while Ferdinand and her retainers must manage the consequences of her unpredictable decisions.
The trailer also promises more direct magical conflict than the earliest portions of the series, including battles where Rozemyne must actively use the power she once struggled merely to survive.
Despite the increased danger, books remain at the center of her plans. Every new responsibility is evaluated according to whether it can help or interfere with the creation of a world where she can read as much as she wants.
Final Thoughts
Ascendance of a Bookworm: Adopted Daughter of an Archduke Cour 2 begins airing in Japan on July 11, 2026.
The third main trailer previews new scenes involving Rozemyne’s family, printing ambitions, noble responsibilities and magical battles.
Adieu performs the new ending theme “Wanna me,” which will receive a television-edit digital release on July 11. Kana Nishino provides the opening theme “Power of Love.”
Yoshiaki Iwasaki directs the adaptation at WIT Studio, with Mariko Kunisawa handling series composition, Aiko Minowa designing the characters and Michiru composing the music.
Yuka Iguchi and Show Hayami continue leading the cast as Rozemyne and Ferdinand.
With the printing industry expanding and Rozemyne confronting both the power of her mana and the expectations of noble society, Cour 2 is preparing to transform her passion for books into a force capable of changing all of Ehrenfest.
