Ascendance of a Bookworm: Adopted Daughter of an Archduke (Season 4)

After her family is attacked by the High Bishop, Myne agrees to become the Archduke's daughter to prevent her family from being executed for attacking a noble, even if it was in self-defense. Gunther, Tuuli, and Effa have now spread the word that Myne is dead. Although they can still see their daughter, they must treat her as a noble and refer to her as Rozemyne, the new name given to her by the Archduke.

Rozemyne first goes to Karstedt's estate, where she learns noble etiquette and is formally accepted as his daughter to help put Archduke Sylvester's plan to rewrite her history into action. According to her new backstory, she is the daughter of Karstedt's third wife, who has since passed away. She was raised in the cathedral, unaware of her noble origins, until Archduke Sylvester recognized her talents and accomplishments and decided to adopt her as his new daughter.

During her baptism, the announcement is made that the Archduke will be adopting her and that she will also be taking over the position of High Bishop following the previous High Bishop's death. As she greets the various nobles, she is unexpectedly pulled away by Wilfried, the Archduke's son. Unaware of her frail condition, he pulls her along too quickly, causing her to pass out. Will Rozemyne be able to adapt to noble society and successfully fulfill her duties as High Bishop?

Ascendance of a Bookworm: Adopted Daughter of an Archduke was amazing. I honestly had my doubts about this season when it first started. The animation style is completely different from the previous three seasons, and I was afraid that her becoming a noble would mean less time spent on her work with books and other business endeavors. However, by the end, I found myself wishing they had spent more time showing her developing relationships with the Archduke's family.

This season was the most enjoyable so far, in my opinion. It also reminded me a little of The Saint's Magic Power Is Omnipotent and The Most Heretical Last Boss Queen: From Villainess to Savior. I also really enjoyed how magic is performed through chanting in this world. In most isekai anime, characters either cast spells without saying anything or simply say something like "Fireball" before casting one. I appreciate the more elaborate approach this series takes.

While there is a bath scene, it doesn't focus on Rozemyne's body. There are also a few swear words throughout the season. If you enjoyed the previous seasons, I would definitely recommend giving this one a try as well.
