Beastars: A Steep Fall From Light

A few years after the events of the manga series, a new threat emerges from the shadows of the torn down Back Alley Market. Animals, both prey and predator, begin to disappear, and attacks are starting to rise again. At the center of it all is a masked figure going by the name of Razor. No one knows who he is, or where he came from, but one thing's for sure. The Beastars have never faced a more potent threat. One with a personal vendetta.

You'll never even see him coming.

(Side note: I have not read the new chapters of "Beast Complex" with Legoshi in them. If there is anything in this story that contradicts events in that manga series, that is why.)
