Twilight: The Children of the Moon

In the Twilight World, werewolves stand among four supernatural species alongside shape-shifters, vampire-human hybrids, and vampires. The Children of the Moon, known as true werewolves, are humans transforming into fearsome wolf-like creatures under the full moon's influence. Unlike shape-shifters, these werewolves possess formidable strength, capable of single-handedly challenging vampires. However, their lack of control over the transformation makes them dangerous.

Our main character, a transmigrater, unwittingly becomes a target for vampires after surviving a near-death encounter with a monstrous creature. Little does he know, he's infected with werewolf venom, marking him as prey for the vampire hunters.
