From Chef to Crafter to Conqueror

Ryo was a chef, an extremely good one at that. Now he's back in time in an alternate dimension and the retainer of a Feudal Japanese Lord, in charge of his defense from an upcoming Mongol invasion. What is a Space Force Food Service Specialist supposed to do?

Accompanied by an extremely advanced Artificial Intelligence, a medieval noble, and his samurai retainers, Ryo sets out to change the known world. At least this dimension's version of it!

With his knowledge of history and the help of his companions can he stop the unstoppable tide of the greatest war machine the East Asian continent has ever known?

Rejoin Ryo as he tries to change history with a little bit of luck, a lot of technical know-how, and some fantastic food!
