High school student Saburo (Shun Oguri) went on a field trip to a period-drama theme town, but after falling from a wall, he’s sent back in time to the Warring States period (1549). Then, he meets a young lord who is the spitting image of him. Due to his poor health, the young lord asks Saburo to act as his double, but the lord is none other than Nobunaga Oda! The guy who unifies the country! Originally convinced he'd entered a special attraction, Saburo witnesses battle right before his eyes, and reality settles in. An entertainment show straight from the Warring States period, Saburo and young warriors from the Oda family attempt to unify the country!
