Ascendance of a Bookworm: Adopted Daughter of an Archduke episode 24, titled Rescue, is scheduled to release on Saturday, October 3, 2026, at 5:30 PM JST on Japanese television networks. For international audiences, the episode will stream on Crunchyroll starting at 1:30 AM Pacific Time on the same day. This marks the penultimate episode of the season, following the intense kidnapping and poisoning cliffhanger from episode 23.
What to Expect in Episode 24
Episode 24 is titled Rescue and picks up directly from the shocking events of the previous episode. The official Japanese synopsis reveals that Rozemyne, captured by attackers, is saved by her grandfather Bonifatius, who springs into action to protect his granddaughter. However, the poison ravaging her body is severe, forcing Ferdinand to make an emergency decision to use Jureve, a powerful magical potion that puts Rozemyne into a long, deep sleep.
The episode will show the aftermath of the attack from multiple perspectives. Rozemyne’s lower city family is relieved that she survived, while Wilfried and Charlotte step in to perform religious duties in her absence. Her lower city friends and temple attendants continue working on book production, and Ferdinand remains by her side, waiting for the moment she awakens.
The previous episode ended with Rozemyne being captured by assailants after Charlotte was targeted during her baptism ceremony. The attackers’ true goal appears to have been Rozemyne herself, not Charlotte.
Episode 23 Recap and Character Story Progress
Episode 23, titled Charlotte’s Baptism Ceremony, aired on September 26, 2026. The episode centers on the baptism of Charlotte, Rozemyne’s younger foster sister, and the political maneuvering surrounding the event.
Rozemyne begins the episode determined to make Charlotte’s baptism perfect. She is visibly moved when Charlotte calls her “Sister Rozemyne” for the first time. During the ceremony, Rozemyne successfully performs a blessing for Charlotte as the high bishop.
Sylvester uses the baptism gathering to publicly address the situation with Wilfried, setting the record straight on what happened with his son and signaling a shift in the political landscape of the duchy.
The ceremony itself unfolds smoothly until the banquet. During the post-baptism banquet, Rozemyne must navigate complex conversations with various nobles, speaking in thinly veiled codes. The episode builds tension with subtle hints of suspicion before a group of attackers bursts through the window.
Angelica, one of Rozemyne’s retainers, makes a strong showing in the ensuing battle, fighting fiercely before being magically flung to catch Charlotte at a critical moment. Bonifatius, Rozemyne’s grandfather, also enters the fight, punching an attacker with enough force to make him explode.
The episode ends on a cliffhanger: Charlotte is captured, and Rozemyne is also taken by the attackers. The finishing moments suggest the entire plot was designed around poisoning and abducting Rozemyne herself, with Charlotte’s kidnapping serving as a distraction.
