In the Japanese version of Frieren: Beyond Journey’s End, Sein is voiced by Yūichi Nakamura. In the English dub, Sein is voiced by Christopher Wehkamp. Nakamura’s performance gives Sein his weary humor, grounded warmth, and understated emotional intelligence, which makes the priest feel distinct the moment he joins Frieren’s party.
Japanese Voice Actor: Yūichi Nakamura
Date of Birth

Full Current Filmography
The list below reflects documented credits verifiable from Intention’s official profile and major public reference sources as of March 25, 2026. Because Nakamura’s career is extensive and public databases do not always align perfectly, this should be treated as a source-backed documented filmography rather than a guaranteed exhaustive list of every role.

Original video animation / films
OVA / ONA / films documented in public sources: Jujutsu Kaisen 0 (Satoru Gojo); Macross Frontier films (Alto Saotome); Fairy Tail films (Gray Fullbuster); The Irregular at Magic High School film projects (Tatsuya Shiba); JoJo’s Bizarre Adventure franchise projects (Bruno Bucciarati). Because the sources reviewed here were stronger on TV and agency listings than on a normalized film-only list, I’m labeling this as documented screen work rather than a complete film-exclusive breakdown.
Video games
Intention’s official profile documents extensive game work, including Genshin Impact (Flins), Touken Ranbu ONLINE (Dōjigiri Yasutsuna), Fatal Fury: City of the Wolves (Kain R. Heinlein), Metaphor: ReFantazio (Louis), Romancing SaGa 2: Revenge of the Seven (Wagnas), Final Fantasy XVI (Dion Lesage), Live A Live (Oersted), Triangle Strategy (Roland Glenbrook), The Great Ace Attorney (Kazuma Asogi), Fire Emblem Fates (Ryoma), Like a Dragon series (Han Joon-gi), Final Fantasy XIV (Thancred), and Final Fantasy XV (Ravus Nox Fleuret).
Dubbing / narration / other documented credits
Intention also lists major dubbing and narration work, including Captain America / Steve Rogers in Marvel projects, Hangman in Top Gun: Maverick, Zenk in Dungeons & Dragons: Honor Among Thieves, Michael Morbius in Morbius, Orion Pax / Optimus Prime in Transformers One, and narration for Japanese television and commercials.
Critical Reception
Nakamura’s strongest formal recognition in the sources I checked is his Best Supporting Actor win at the 16th Seiyu Awards, plus later MVS (Most Valuable Seiyū) recognition in public award listings. Those awards fit the shape of his career: he has been a consistent first-choice lead or major supporting presence across mainstream anime for more than a decade.
For Frieren specifically, Sein’s arrival was treated as a significant cast addition because he joins the core traveling group, and Nakamura’s name carried immediate recognition thanks to his long list of marquee roles. That makes his casting notable not just as another supporting credit, but as part of the series’ central ensemble. That final point is an inference based on cast positioning and the prominence of his role in official agency and cast listings.

English Voice Actor: Christopher Wehkamp
Date of Birth
February 25. Behind The Voice Actors publicly lists Christopher Wehkamp’s birth date as February 25, but the source snippet I found did not include a birth year, so I’m not stating one here as verified.
About Christopher
Christopher Wehkamp is an American voice actor and director known for anime dubbing, video game work, and ADR-related production roles. Public profiles identify him with major performances including Shota Aizawa / Eraser Head in My Hero Academia, Susumu Kodai in Star Blazers: Space Battleship Yamato 2199, Miles Edgeworth, and Sein in Frieren: Beyond Journey’s End. His official website presents him as a professional voice actor and voice-over artist, while IMDb describes him as an actor and director working in anime television series, films, and games.
Hometown
IMDb’s biography page says Wehkamp was born in Marietta, Georgia, USA and later lived in Dallas, Texas. I did not find a separate official source clearly stating a hometown in the narrower sense, so Marietta is the most supportable publicly documented origin point from the sources I checked.
Career Highlights
For Frieren: Beyond Journey’s End, Wehkamp is the English dub voice of Sein, and Behind The Voice Actors lists him specifically for that role. Crunchyroll also confirms the series is available in English dub, supporting the existence of the English-language performance context.
Outside Frieren, the most consistently highlighted roles in the public sources I checked are Shota Aizawa / Eraser Head in My Hero Academia, Susumu Kodai in Star Blazers: Space Battleship Yamato 2199, and *Miles Edgeworth. IMDb also summarizes him as being especially known for work associated with My Hero Academia, Tokyo Ghoul, and Attack on Titan.
Full Current Filmography
The list below reflects documented publicly accessible credits I could verify from major reference sources as of March 25, 2026. Because public dub databases do not always align perfectly across platforms, this should be treated as a source-backed documented filmography and may not be exhaustive.
Anime / TV animation
Known major documented credits: My Hero Academia (Shota Aizawa / Eraser Head), Star Blazers: Space Battleship Yamato 2199 (Susumu Kodai), Tokyo Ghoul, Attack on Titan, and Frieren: Beyond Journey’s End (Sein). These are the clearest, repeatedly surfaced credits across the public sources I checked.
Additional documented anime credits from public TV listings: Hyouka, One Piece, Dragon Ball Super, Overlord, Radiant, SSSS.Gridman, Steins;Gate 0, Fuuka, Tsukigakirei, The Royal Tutor, Interviews with Monster Girls, Knight’s & Magic, A Certain Magical Index III, How NOT to Summon a Demon Lord, Dr. STONE, Fire Force, Sarazanmai, The Ones Within, Midnight Occult Civil Servants, One Piece: Episode of Skypiea, Stone, Hensuki, and others listed by TV Guide. Because that source provides a broad credits roll rather than a normalized role-by-role dub breakdown, I’m presenting these as documented titles rather than a fully resolved character list.
Animated films / specials
Public credits also include animated film and special appearances such as Project Itoh: Genocidal Organ, One Piece Film Z, One Piece: 3D2Y, One Piece Heart of Gold, One Piece: Episode of Sabo, One Piece: Episode of Skypiea, City Hunter: Shinjuku Private Eyes, and New Initial D the Movie entries. Again, the source I reviewed was stronger on title-level credit aggregation than on fully normalized character attribution.
Video games
IMDb and public profiles identify Wehkamp as working in video games as well as anime, but the search results I reviewed did not provide a clean role-by-role master list comparable to the acting credits pages for some other performers. I can verify that he is publicly described as active in games, but not enough from the checked sources to responsibly publish a more complete normalized gameography here.
Voice direction / ADR work
Wehkamp is also publicly credited for direction-related work. TV Guide lists him under ADR director for Banished from the Hero’s Party, I Decided to Live a Quiet Life in the Countryside and assistant director for SK8 the Infinity. IMDb likewise describes him as both an actor and director.
Critical Reception
Wehkamp’s public critical profile is driven more by sustained prominence in English dubbing than by a single award narrative in the sources I checked. Behind The Voice Actors highlights Eraser Head / Shota Aizawa, Susumu Kodai, and Miles Edgeworth as the roles he is best known for, which is a useful shorthand for the performances most associated with his name in public-facing voice-acting coverage.
For Frieren specifically, Wehkamp’s Sein is part of the established English dub cast tracked by Behind The Voice Actors, and Crunchyroll’s continuing dub support for the series reinforces the visibility of that performance within the franchise’s English-language release. Since Sein joins the main traveling group for a significant stretch, Wehkamp’s role carries more weight than a one-off guest part; that last point is an inference based on the character’s placement in the series.
