Donatsu is a cute chubby ninja whose story you follow in Ninja Chowdown. He loves donuts more than anything!

The Dough-jo Donuttery, a food chain and a ninja dojo at the same time, is climbing to the top of the food chain... the top of the chain of world's food chains! Like every other one in this world, run by cuisine champions and competing food clans. A strong flavor breeds an equally strong fighting spirit!

The adventure begins when The Traveling Rollnin's leader, Sushi Sam, steals the Know-nut, the Doughnut of Ultimate Knowledge, from the Dough-jo. And no one but Donatsu is skilled and badass enough to get it back!
