Black Torch (English), Season 1

Jiro Azuma is not your average high schooler. Hailing from a long line of ninja, Jiro has been brought up by his grandfather in the ancient warrior art of the shinobi. Jiro also happens to be a particularly skilled communicator able to converse with the animal world. But life takes an abrupt turn thanks to a mysterious encounter in the forest with an injured black cat named Rago. Only, Rago’s feline appearance is deceiving… It turns out the “ordinary” cat is the stuff of mononoke legend–the Black Star of Doom! Swarming in the shadows are more mononoke, eager to exploit Rago’s uniquely immense powers. To fight back against the tide of dark spirits, the undercover Bureau of Espionage is poised to seek and destroy. Of course, everyone has their motives when it comes to Rago’s powers. But Jiro and Rago are ready. A shinobi clash between boy and mononoke is about to ignite!
