Otakon Bookworm Panel: Staff Energy, Battle PV & Witch Hat Collab

Otakon 2026’s Ascendance of a Bookworm: Adopted Daughter of an Archduke panel felt less like a standard industry Q&A and more like a pep rally for noble intrigue. Producer Goshi Yoshida burst into the room, circled the crowd, and high-fived fans down the center aisle—an entrance that matched how hard the crew is swinging for this WIT Studio chapter of the biblio-fantasy.

Voice actress Yuka Iguchi (Rozemyne) gushed that the book-obsessed heroine remains one of the cutest roles she’s ever voiced, while trading sessions with veterans such as Kazuhiko Inoue (Sylvester). Director Yoshiaki Iwasaki said the cast is so locked into their characters that he barely needs to nudge them anymore. Original author Miya Kazuki still sits in on recordings, which keeps everyone sharp: the team debates how to expand scale—especially as fights grow fiercer—beyond what’s spelled out on the page.

Fans got a special promo reel with upcoming cuts: Sylvester teaming with Rozemyne, her magic training ramping up, and a clash against the winter lord, framed as a massive white tiger. Iguchi flagged combat-prep scenes as personal favorites and teased a Ferdinand moment she first loved in an audio drama. Staff also hinted that more characters will share the spotlight, that most of the crew has read the light novels cover to cover, and that romance may finally step past purely familial warmth.

The panel closed on a crossover promo pairing Bookworm with Witch Hat Atelier—no new animation, but a clever cut emphasizing ink-and-magic craft from two series whose authors are real-life friends. If Otakon’s room energy is any gauge, this adopted-daughter arc is charging into a louder, more spectacular stretch of the story.
