Erika Harlacher and Brianna Knickerbocker are seasoned pros, while the Merrell twins bring a fresh, relatable energy for viewers who enjoy seeing familiar internet voices in anime.

Character Highlights
Koyuki Hikawa: The Wallflower with Depth
Koyuki is frequently misunderstood. Her quiet demeanor and “cold” exterior mask deep social anxiety, making her one of the most relatable protagonists in recent anime. Erika Harlacher’s voice captures this perfectly, balancing fragility with moments of strength. For viewers who’ve ever felt invisible in their own social circles, Koyuki’s journey resonates on a personal level.
Miki Azumi: Sunshine in the Hallways
Miki is Koyuki’s cheerful childhood friend and emotional anchor. Brianna Knickerbocker brings a warmth and sincerity to Miki that makes every interaction sparkle. Her performance is a reminder of why side characters can sometimes leave a bigger emotional impact than the protagonist.
Minato Amamiya: Calm in the Chaos
Minato is approachable and unassuming but becomes a crucial bridge in Koyuki’s world. Kyle McCarley’s nuanced voice work gives Minato a grounded presence that balances the more intense emotional moments of the series.
Yota Hino: The Friend You Can Count On
Yota’s thoughtful nature is perfectly embodied by Jason Griffith. His experience as Sonic’s voice shines through in a performance that’s both lively and heartfelt, making Yota a standout in the ensemble.
The Merrell Twins: Sora & Miharu
Casting popular YouTubers Veronica and Vanessa Merrell was a bold move, but it pays off. Their chemistry translates effortlessly, and they manage to be funny, empathetic, and emotionally resonant—a rare feat in voice acting. Social media buzz has been intense since the announcement, and fans are clearly excited to hear these voices in a serious anime setting.

VSI Los Angeles also brought together an impressive supporting cast, including Stephanie Acevedo, Jennifer Sun Bell, Khoi Dao, Xanthe Huynh, Alan Lee, Gilli Messer, Kayli Mills, Michael C. Pizzuto, Kevin Andrew Rivera, Colby Rummell, and Laura Stahl. These voices fill the school environment with authenticity, making every classroom scene feel lived-in.
