Karneval - S01

A young boy named Nai is searching for his lost friend when he’s captured by a stunning yet terrifying woman who feasts on human flesh. Meanwhile, Gareki, a skilled thief, is busy robbing her lavish home. When he creates a distraction, he agrees to help Nai escape-but their plan is foiled when the woman returns and transforms into a monstrous creature, forcing them to flee. While on the run, Nai and Gareki are discovered by "Circus," a government agency that handles crimes too dangerous for the police and protects people from "varuga"-horrific monsters that prey on humans. Hoping it will lead Nai closer to his friend, the two decide to join Circus. As they journey through perilous encounters with varuga, they slowly unravel the mysteries of a sinister organization called Kafka.
