Toto Warsito, the Indonesian Voice of Muzan in Demon Slayer, Dies. He Started With Telenovelas in 1993
Toto Warsito, the voice of Muzan Kibutsuji in the Indonesian dub of Demon Slayer, of Henry Henderson in Spy x Family and of Eisen in Frieren, died on the evening of Wednesday, 7 October. The memorial card his studio shared gives his years as 1973 to 2026. English speaking anime fans only heard on Sunday, when the Indonesian site KAORI Nusantara published its report in English, four days after breaking the story at home.
No cause of death has been given. The Jakarta news site medcom.id, which carried the story on 8 October, said plainly that the cause and any medical history were not yet known. Nothing has changed since.
A dubbing school broke the news
The announcement didn’t come from a network or a studio. It came from Voice Institute Indonesia, a school for voice work, on its Instagram account, and medcom.id ran the post’s wording the next day. “Toto Warsito, a voice actor who had been working since 1993, is reported to have died on the evening of Wednesday, 7 October 2026,” the school wrote. It signed off with a farewell that Indonesian fans have been repeating ever since.
“Safe travels, Toto Warsito. Thank you for bringing so many characters to life through your voice.”

The picture medcom.id ran with its report was a black and white memorial card posted by ATM Studio, the dubbing house that records Muse Indonesia’s Indonesian versions of Demon Slayer and Spy x Family. It shows Warsito grinning in a dark jacket, arms folded, with the years 1973 to 2026 under his name. For a man who spent his career unseen, it’s the picture most of his listeners are meeting him by.

Thirty three years, from telenovelas to demons
KAORI Nusantara, which covers anime and Japanese pop culture for Indonesian readers, traces his career back to 1993 and the Arvisco studio, which it calls legendary. His first run of fame came through SCTV, the network that filled Indonesian afternoons with Latin American telenovelas. In Amigos por siempre he was Neftalí Güemes. In the animated Jumanji series, also on SCTV, he was Van Pelt, “the character who kept chasing Alan Parrish inside the world of the Jumanji game,” as the site put it.
VoiceEditSuiteClean a session in ninety seconds, not three hours.Anime came late. Muse Indonesia, the distributor that streams licensed anime on YouTube, only started adding Indonesian voice tracks to its shows in 2021, and by the middle of 2022 KAORI counted Kimetsu no Yaiba, Sabikui Bisco, Attack on Titan and Spy x Family among the titles dubbed at ATM Studio. That’s where Warsito picked up the roles the obituaries now lead with: Muzan, the demon king and final enemy of Demon Slayer; Henry Henderson, the housemaster at Eden Academy in Spy x Family; and Eisen, the dwarf warrior in Frieren.
The range is the story. A telenovela character, a big game hunter in a Saturday morning cartoon, a soft spoken monster and an old dwarf, all in one voice that Indonesian viewers heard for three decades without, most of them, ever learning his name.
A narrator’s secret, half told
In June 2022 Muse Indonesia invited him and a fellow Spy x Family voice to an online chat it called #Museminar. KAORI wrote it up because of one slip. Around the 50 minute mark a viewer wrote in: “I still want to hear your voice in the next anime. I’m a fan.” The host asked whether there was a new project. Warsito said he was narrating something, and that he thought it might be an anime. Pressed on which, he answered: “I don’t know. I only just started. I just made a sample earlier.”
The site never pinned down which show it was. It’s a small moment, but it’s the only recorded interview with him most fans will find this week, and it reads like the career itself: working, unbothered by billing, not always sure what the show was going to be called.
He taught the craft on his own channel
Warsito also taught. On his YouTube channel, PAKDE TO, he posted a series called Belajar Dubbing, “learn dubbing”, recorded at a home microphone in an orange T-shirt, with a clip from the 1989 Batman, subtitled in Indonesian, on screen as his practice material. The description under the second episode calls him “a professional dubber and dialogue director who has been in that world for more than 25 years.” The frames on this page come from that lesson.

Much of the rest of the channel is song covers, which tells you something else about a voice that spent its working life being other people: when it was his own, he sang.
Why a death in Jakarta matters outside Jakarta
Indonesian anime dubbing is young. Muse Indonesia began adding Indonesian voices in 2021, and KAORI’s 2022 list of dubbed titles ran to six shows across two studios. The people who gave that new line of work a professional floor were veterans like Warsito, with three decades of SCTV telenovelas behind them and the habit of turning up, reading the line and going home. Every dubbing market that grows fast leans on a few of those people. Indonesia has just lost one.
KAORI Nusantara ended its English report with a prayer: “May God accept his deeds, forgive his sins, and grant fortitude to his family. May his legacy continue to live on and be remembered for generations.” Its Indonesian edition went out under a banner reading Selamat Jalan, safe travels, with his face beside Muzan’s.
