The highly anticipated anime adaptation of Kōcha Agasawa’s beloved romantic comedy manga, “You and I Are Polar Opposites” (Seihantai na Kimi to Boku), is steadily building its ensemble, with recent announcements confirming additional talented voice actors joining the roster. Among the latest additions, Kokoro Ōmori and Tomori Kusunoki are set to lend their voices to key schoolmates, enriching the vibrant world of the series slated for a January 2026 premiere.
Originally a popular one-shot, “You and I Are Polar Opposites” garnered significant acclaim before its serialization on Shueisha’s Shōnen Jump+ platform, captivating readers with its endearing portrayal of contrasting personalities in a high school romance. The anime adaptation promises to bring this charming story to life, with a growing cast that underscores the series’ rich character dynamics.
The World of “You and I Are Polar Opposites”: A Tale of Contrasting Hearts
At its core, “You and I Are Polar Opposites” explores the sweet, often awkward, journey of high school students Miyu Suzuki and Yusuke Tani. Suzuki is an energetic, outgoing girl who often finds herself conforming to peer expectations, even when it goes against her true feelings. In stark contrast, Tani is a quiet, introverted boy who isn’t afraid to speak his mind, regardless of others’ opinions.
Despite their seemingly irreconcilable differences, an undeniable attraction blossoms between them. Suzuki develops a crush on Tani, admiring his authenticity and straightforward nature, while Tani secretly harbors feelings for the lively Suzuki. The series beautifully depicts their burgeoning relationship, as they navigate the complexities of teenage dating, self-discovery, and understanding someone truly opposite to oneself.
Expanding the Ensemble: New Voice Talent Joins the Cast
The latest casting revelations have added depth to the supporting character lineup. Kokoro Ōmori has been cast as Nishi, and Tomori Kusunoki will voice Honda, both schoolmates of the main duo. These roles are crucial in providing external perspectives and interactions that further shape Suzuki and Tani’s personal growth and romantic development.
Further expanding the cast of classmates, Miyuri Shimabukuro is set to portray Azuma, described as a “blonde bombshell” friend of Suzuki with a mature yet jaded outlook on romance. Wataru Kato joins as Taira, a cynical and self-doubting boy who is friends with Azuma, forming a popular duo nicknamed “TairAzuma.” Additionally, Yuna Taniguchi voices Watanabe, a cheerful and free-spirited classmate, while Konatsu Hirabayashi takes on the role of Sato, a quiet and cool-headed observer of her friends’ love lives.
Meet the Main Duo: Suzuki and Tani
