The anime adaptation of Kamome Shirahama’s acclaimed fantasy manga, Witch Hat Atelier, is deepening its cast as it enters a critical narrative phase. The production team has announced the addition of two significant voice actors for the upcoming “Second Pentagram Test Arc”: veteran performer Ryusei Nakao will voice the enigmatic Brimmed Cap member Sasaran, while Hiiro Ishibashi has been cast as Euini. These additions signal a major escalation in the story’s scope as the series builds toward one of its most pivotal storylines.
Who Are Sasaran and Euini in the Witch Hat Atelier Story?
Ryusei Nakao, a voice acting legend known for iconic roles such as Frieza in Dragon Ball and Mayuri Kurotsuchi in Bleach, will embody Sasaran. Sasaran is a member of the mysterious and antagonistic Brimmed Caps, a group of rogue magicians who operate outside the established magical order. Nakao revealed that his character makes his debut in Episode 10, titled “A Promise in Silver,” which was released today. Hiiro Ishibashi joins as Euini, a character set to appear in Episode 11 on June 8. Their introduction marks the beginning of the Second Pentagram Test Arc, a section of the manga known for its intense magical exams and deepening conflicts.
Voice Actors Reflect on Joining the Fantasy Series
In statements provided by the production committee, both actors expressed enthusiasm for the world of Witch Hat Atelier. Nakao shared a personal connection to the material, stating, “I was looking forward to Witch Hat Atelier because I really liked its world. And I’ve become very fond of playing Sasaran, a character shrouded in mystery. I’m excited to see how the story develops.” His comments highlight the allure of the series’ richly detailed universe, which blends a soft magic system with intricate moral questions.
Ishibashi, who joins the cast midway through production, described the experience as a compelling challenge. “The more I read the original manga, the more I found myself completely drawn into its world. It’s a great honor to be part of a work that is loved around the world,” he said. He added, “I joined the recording sessions midway through production, but I was inspired by the passion of Motomura-san, the rest of the cast, and the production staff. I gave everything I had to bring Euini to life. There are still many things I can’t talk about yet, but… the kindness he keeps hidden is genuine!”
The Second Pentagram Test Arc: A Defining Challenge for the Protagonists
The “Second Pentagram Test Arc” represents a significant turning point in the narrative. In the original manga, this storyline follows the young apprentice witches, led by the determined Coco, as they face a series of grueling examinations designed to test their magical aptitude, creativity, and ethical judgment. This arc is notable for expanding the world’s magical lore—particularly the rules governing the forbidden “Witch Hat” techniques—and for introducing new characters who challenge the protagonists’ understanding of magic.
The introduction of Sasaran and Euini is not merely a casting announcement; it directly signals the arrival of key antagonists and allies who complicate the central conflict between the lawful magic society and the renegade Brimmed Caps.
Why the Witch Hat Atelier Anime Faces Unique Production Challenges
The arrival of these new characters comes amid a broader conversation about the anime’s production. Director Ayumu Watanabe recently described the adaptation as a “reckless undertaking,” citing the immense difficulty of translating Shirahama’s highly detailed and painterly art style into fluid animation. Studio BUG FILMS, the production house responsible for the series, bears the weight of this visual ambition. The director’s candid assessment underscores the high stakes for the studio, which must balance fidelity to the source material with the practical constraints of animation. The Second Pentagram Test Arc, with its complex magical sequences and expressive character work, will serve as a major test of the studio’s capabilities.
What Is the Background and Global Reach of the Witch Hat Atelier Manga?
To understand the significance of this anime adaptation, one must appreciate the source material’s stature. Shirahama’s manga, serialized in Kodansha’s Morning Two magazine since July 2016, has achieved remarkable critical and commercial success. As of April 2026, it has amassed 16 compiled volumes and has surpassed 7 million copies in circulation. The series earned international prestige by winning the Harvey Award for Best Manga in 2020 and the Eisner Award for Best U.S. Edition of International Material—Asia, a rare double honor that places it among the most influential manga of the decade.
The English-language publisher Kodansha USA describes the premise: In a world where magic is treated as a mundane wonder, young Coco dreams of becoming a witch despite not being born with magical talent. Her life changes when she meets Qifrey, a mysterious traveling magician, and discovers that the secrets of magic are not limited by birthright. This coming-of-age story, rooted in curiosity and the love of craftsmanship, has resonated with a global audience.
How the New Cast Supports the Series’ Growing Ambition
The casting of Nakao and Ishibashi aligns with the production’s overall goal of delivering a faithful and high-impact adaptation. Nakao’s distinctive vocal range is ideally suited for a character like Sasaran, whose mystery and potential menace require a nuanced performance. Ishibashi, a rising talent, brings fresh energy to Euini, a role that involves hidden depths. Their commitment, as expressed in their comments, suggests that the recording sessions for the Second Pentagram Test Arc are being executed with meticulous care.
When Do the New Characters Appear and How Can Fans Watch?
For viewers tracking the series as it airs, Sasaran appears in Episode 10, which is now available. Euini will make his debut in Episode 11, scheduled for June 8. These episodes are part of the ongoing weekly release schedule, and they mark the formal entry into the Second Pentagram Test Arc. Fans can watch the series on major streaming platforms that hold the license for the English-subbed and dubbed versions.
The announcement of these cast additions, paired with the director’s candid remarks about the production’s difficulty, paints a picture of an anime that is as ambitious as it is risky. The success of the adaptation hinges on how well it navigates the transition from the manga’s static, breathtaking panels to the dynamic, flowing medium of animation. The arrival of Sasaran and Euini in the coming episodes will provide the first real evidence of whether Studio BUG FILMS can meet that formidable challenge and deliver the Witch Hat Atelier experience that fans have been waiting for.
