Amidst his broken life, Police Officer Grayson Reed is about to be thrown into the middle of a feud between the five angels of Heaven and the leader of Hell. As faith ends in the world around him, Grayson will be faced with an ultimate choice that could decide the fate of our world.

Yam Roll tells the story of an exotic land of sushi and how one of its inhabitants, a super-powered cab driver named Yam Roll, braves monsters and bad guys all in the name of unrequited love. Despite being well liked in Happy Kingdom due to his good nature and sweet, root-vegetable flavouring, Yam Roll is still a frustrated guy. Why? Because he is hopelessly in love with the town sweetheart, a spicy tuna roll named Minamiko.
