The success of a deadpan comedy depends heavily on timing. The Disastrous Life of Saiki K. relies on deadpan delivery, rapid-fire internal monologues, and chaotic energy. Behind Kusuo Saiki and his eccentric classmates stand talented Japanese seiyū and English dub actors who bring this psychic comedy to life.
If you want to know who voices your favorite PK Academy students, you're in the right place. We'll break down the primary voice cast, explore the differences between the original Japanese performances and the English adaptations, and look at the cast changes that happened when the series moved to Netflix for Reawakened.
The Main Cast Behind the Psychic Chaos
Every great comedy needs a straight man who is secretly losing his mind. Kusuo Saiki plays this role perfectly, surrounded by peers who make quiet living impossible.
Kusuo Saiki
- Japanese Voice: Hiroshi Kamiya
- English Voice (Seasons 1-2): Jerry Jewell
- English Voice (Reawakened): Kyle McCarley
Hiroshi Kamiya captures Saiki's world-weary, deadpan exhaustion with precision. Kamiya is famous for voicing other iconic anime characters like Levi Ackerman in Attack on Titan and Koyomi Araragi in the Monogatari series. In the Funimation English dub, Jerry Jewell handles Saiki's internal sarcasm brilliantly. When Netflix produced Reawakened, the English cast changed completely, and Kyle McCarley took over the role, offering a slightly different, more subdued tone.
Riki Nendō
- Japanese Voice: Daisuke Ono
- English Voice (Seasons 1-2): David Wald
- English Voice (Reawakened): Kaiji Tang
Riki Nendō has no psychic resistance, an empty head, and a heart of gold. Daisuke Ono uses a deep, raspy delivery to voice Nendō in Japanese, highlighting his complete lack of intelligence. David Wald matched this energy in the Funimation dub with a hilariously blunt performance. Fun fact: Daisuke Ono also voices Nendō's equally block-headed father in the series.
Shun Kaidō
- Japanese Voice: Nobunaga Shimazaki
- English Voice (Seasons 1-2): Micah Solusod
- English Voice (Reawakened): Zach Aguilar
Shun Kaidō lives in a constant state of chuunibyou delusion, convinced that his right hand contains a dark seal. Nobunaga Shimazaki leans hard into Kaidō's dramatic, high-pitched outbursts and swift panics. Micah Solusod mirrors this theatrical desperation in the English dub, making Kaidō's fragile ego one of the funniest parts of the show.
PK Academy Classmates and Supporting Voices
The supporting cast drives the narrative forward by dragging Saiki into unwanted social situations.
Kokomi Teruhashi
- Japanese Voice: Ai Kayano
- English Voice (Seasons 1-2): Tia Ballard
- English Voice (Reawakened): Kayli Mills
Kokomi Teruhashi is the self-proclaimed perfect pretty girl whose internal catchphrase is "Off-guard!" Ai Kayano plays her with a sweet, bubbly exterior that hides a fiercely competitive ego. Tia Ballard captures this dual personality perfectly in English, shifting smoothly between angelic public charm and petty internal monologues.
Reita Toritsuka
- Japanese Voice: Natsuki Hanae
- English Voice (Seasons 1-2): Joel McDonald
- English Voice (Reawakened): Kellen Goff
Reita Toritsuka is a medium who knows about Saiki's powers and wants to use them to get popular with girls. Natsuki Hanae injects frantic, energetic desperation into Toritsuka's performance. Joel McDonald adopts a fast-talking, sleazy charm in the English dub that sells Toritsuka's constant failures.
Understanding the Saiki K. English Dub Recasting
If you watched the original television series on Crunchyroll and later jumped to Netflix's Reawakened, you likely noticed that every single English voice actor changed.
The original television series was dubbed by Funimation in Texas, featuring their regular stable of voice talent. When Netflix acquired the rights to distribute Reawakened, production shifted to VSI Los Angeles. Industry union differences and localized studio logistics meant that none of the original Texas-based English cast members were brought back.
Meanwhile, the Japanese cast remained completely consistent across all seasons, anchored by veteran studio J.C.Staff production choices. If you prefer consistency in your audio, sticking with the Japanese sub version ensures you hear Hiroshi Kamiya and the original crew throughout the entire run.
