Leviathan OTT Release Date: If you’re a fan of steampunk, anime, or just love a good story with sky-faring monsters and runaway royals, mark your calendars. Leviathan, the anime adaptation of Scott Westerfeld’s bestselling novel, is landing on Netflix on July 10, and it's one of the biggest anime premieres of the year.

It's being crafted by some of the most respected names in the industry - Studio Orange, known for their jaw-dropping CG animation in BEASTARS and Trigun Stampede, and Qubic Pictures, the creative force behind Eden and Star Wars: Visions. Together, they’re bringing Westerfeld’s alternate World War I universe to life like never before with walking tanks, flying whales, and a living airship that’s as much a character as the people aboard it.

What’s the plot of Leviathan?

Set in an alternate 1914, Leviathan reimagines the start of World War I through a steampunk lens. The world is divided into two technological factions: the Darwinists, who engineer living creatures into war machines, and the Clankers, who rely on iron, gears, and diesel.

At the heart of it all are Prince Aleksandar, a young heir of the Austro-Hungarian Empire forced into hiding after his parents’ assassination, and Deryn Sharp, a brilliant Scottish girl who disguises herself as a boy to serve in the British Air Service. Their fates collide aboard the HMS Leviathan, a massive genetically modified whale-ship that floats across the sky as part of the British fleet.

Meet the cast and crew of Leviathan

Leviathan brings together an elite voice cast:

  • Ayumu Murase (Haikyu!!, Devilman Crybaby) as Prince Aleksandar (Alek)
  • Natsumi Fujiwara (Spy x Family, The Orbital Children) as Deryn Sharp

Directed by Christophe Ferreira, Leviathan is written by Yuichiro Kido. The CG direction is being handled by heavyweights Takayuki Miyakoda, Maiko Iketani, Syunsuke Aoki, and Tadao Morohashi, with Eiji Inomoto as the CG Chief Director. The score is composed by Nobuko Toda and Kazuma Jinnouchi (Ghost in the Shell: SAC_2045, Metal Gear Solid 4), with original songs by none other than Joe Hisaishi, the legend behind Studio Ghibli classics like Spirited Away and Princess Mononoke.
