Constantin von Jascheroff is a German actor and voice actor born in Berlin on March 5, 1986, who has become a prominent figure in the German dubbing industry for anime and international film. Coming from a family of actors, he is the son of Mario and Juana-Maria von Jascheroff and began his career in front of the camera as a child, making his film debut at the age of eleven. While he has an extensive list of live-action credits, including an award for Best Leading Actor at the Munich Film Festival in 2005, his voice is widely recognized by German anime fans for leading roles in major series.

Jascheroff's work in anime dubbing is extensive and spans over two decades. He has lent his voice to a wide variety of characters, from young protagonists to anti-heroes. Some of his earliest known anime roles include voicing Soichiro Arima in Kare Kano in 1998 and Syrus Truesdale in Yu-Gi-Oh! GX. He is also the German voice of Sora from the Kingdom Hearts video game series.

In recent years, Jascheroff has voiced some of the most iconic characters in modern anime. He is the German voice of Tanjirou Kamado in the hit series Demon Slayer: Kimetsu no Yaiba, a role he has reprised for the film Demon Slayer: Kimetsu no Yaiba - The Movie: Mugen Train and subsequent compilations. He also voices the ambitious David Martinez in the cyberpunk thriller Cyberpunk: Edgerunners. His range extends to delinquent characters as well; he is the German voice of the charismatic and feared Manjiro "Mikey" Sano in Tokyo Revengers. His other notable anime roles include Lui Shirosagi in the Beyblade Burst series, Yukiteru Amano in Mirai Nikki and its sequel Mirai Nikki Redial, Shun in Makoto Shinkai's Children Who Chase Lost Voices, and Mitsuru Ashikawa in Brave Story.

Throughout his voice acting career, Jascheroff has frequently collaborated with Berlin-based studios, particularly the Oxygen Sound Studios, which produced the German dubs for both Demon Slayer and Tokyo Revengers. This has led to him working alongside a regular ensemble of German voice actors, such as Dirk Petrick (Zenitsu Agatsuma), Julia Meynen (Nezuko Kamado), and Julian Tennstedt (Draken), among others. His ability to portray both kind-hearted heroes and complex, volatile characters has established him as one of the leading voices for anime protagonists in Germany.
