Season 1
Synopsis
Sirius the Jaeger (2018), Season 1 is a twelve-episode vampire-hunting anime you can watch online on iFILM, set in the shadows of 1930s imperial Tokyo.
A band of hunters carries its weapons hidden inside instrument cases, tracking vampires from a Shanghai raid across the sea to Japan. Among them is Yuliy, a young werewolf whose village was burned down by the same creatures. What begins as a hunt narrows into something personal: the vampires are after a relic called the Ark of Sirius, and the trail keeps dragging Yuliy back toward his own past — a brother he believed dead, a father he can barely remember.
Produced by P.A. Works, the show tells one complete story across a dozen episodes — no filler arcs, just momentum and the cold mood of pre-war Japan. A good pick if you like short, self-contained action anime about hunters and monsters. Stream Sirius the Jaeger Season 1 online on iFILM.
