Oh, the voice cast of 'Ao no Exorcist' is absolutely stellar! The main protagonist, Rin Okumura, is voiced by Nobuhiko Okamoto, who brings this fiery, rebellious energy to the role that’s just perfect. Okamoto’s range is insane—he nails Rin’s hotheadedness but also those quieter, more vulnerable moments. Then there’s Yukio Okumura, Rin’s twin brother, voiced by Jun Fukuyama. Fukuyama’s calm, collected tone contrasts so well with Okamoto’s intensity, and he really sells Yukio’s intellectual yet emotionally guarded personality.
Shiemi Moriyama, the sweet and shy herbalist, is voiced by Kana Hanazawa. Her voice is like honey—soft and gentle, which fits Shiemi’s innocent demeanor perfectly. Ryuji Suguro, the tough but loyal exorcist-in-training, is played by Kazuya Nakai, who’s got that rough, commanding voice that makes Ryuji feel like a force to be reckoned with. And let’s not forget Izumo Kamiki, the tsundere shrine maiden, voiced by Eri Kitamura. Kitamura’s sharp, sarcastic delivery is spot-on for Izumo’s prickly exterior, but she also layers in just enough warmth to hint at the character’s deeper feelings.
The supporting cast is just as impressive. Shura Kirigakure, the laid-back but deadly exorcist, is voiced by Rina Satou, who balances humor and menace effortlessly. Mephisto Pheles, the enigmatic and theatrical demon king, is played by Hiroshi Kamiya, and oh man, Kamiya’s performance is a masterclass in charismatic villainy. His playful, almost singsong delivery makes Mephisto endlessly entertaining. Even the minor characters have standout performances, like Keiji Fujiwara as Fujimoto (Rin and Yukio’s adoptive father), whose gruff but loving tone adds so much heart to the story.
What I love about this cast is how they all mesh together. The dynamics feel so natural, whether it’s the banter between Rin and Ryuji or the tense exchanges between Yukio and Mephisto. It’s one of those rare cases where the voices don’t just fit the characters—they elevate them. Every rewatch reminds me how much the voice acting contributes to the show’s emotional punch and humor. If you haven’t already, I highly recommend checking out the Japanese version just to appreciate how much these actors bring to the table.
