No Promises Large Enough

After their world was turned upside down, two journalists race to uncover the supernatural force driving Japan's criminal underworld while coming to terms with their own emerging powers. 

The head-collecting serial killer was only the beginning. Akio and Masami find themselves more than a little changed from the experience. Now the demon hunter who helped them has gone missing, and his brainy teenage apprentice requests their help. 

To track him down, they must confront Japan's most powerful and dangerous criminal organization: the yakuza. Fueled by a supernatural secret, the gangsters are expanding at an alarming rate, set to take over all of Japan, perhaps even the world. As the two reporters struggle with their new abilities, they must face and defeat who or what is behind the aggressive yakuza syndicate.
