About Leviathan

Here is what Leviathan (リヴァイアサン) is about, retold in plain terms: an adventure, mecha and sci-fi anime by Orange and Qubic Pictures (2025). What the story covers: Set in a war-torn reimagining of 1914, Leviathan follows Alek, a fugitive prince of the Austro-Hungarian Empire, and Deryn Sharp, a daring young girl disguised as a boy to serve in the British Air Service. When fate throws them together aboard the HMS Leviathan, a massive, living airship made from genetically engineered creatures, they embark on a world-changing adventure that will challenge everything they know about war, loyalty.

In an adventure series like this, exploration, new locations and a steady sense of momentum drive the story. Voice work is led by Ayumu Murase as Aleksandar von Hohenberg and Shunsuke Sakuya as Volger Hakushaku.

Think of it as a pick for anyone who enjoys travel-the-world storytelling. With 12 episodes in total, there is enough room for the story to develop.

Production & Appeal

Because it leans on adventure, exploration, new locations and a steady sense of momentum drive the story. Its 6.6/10 score suggests opinions are split, so it suits viewers who already like the genre. Voice casting, including Ayumu Murase as Aleksandar von Hohenberg, adds to the appeal for fans who follow seiyuu. Released in 2025, it competed with that season's other new series for attention.
