A broke engineer and a cowardly samurai build a steam-powered car and race across 1890s America because staying in Japan means execution. What sounds like a setup for a road-trip comedy becomes a genuinely unhinged adventure where the premise refuses to apologize for itself, and neither do the characters. Appare solves impossible problems with absolute confidence while Kosame panics at everything, and somehow that dynamic never gets old because the show keeps throwing weirder obstacles at them. The main character's genius makes some battles feel predetermined, which dulls the tension. What carries you through is pure momentum, bizarre creativity, and two idiots in a metal box discovering that the real treasure was the chaos they caused along the way.

A brilliant engineer and a cowardly samurai end up adrift at sea and are carried to Los Angeles with no money and no plan. Appare Sorano is a gifted inventor from rural Japan in the late 19th century, clever with machines but awkward with people. Kosame Isshiki is a shrewd, capable swordsman whose courage tends to fail him, and he was assigned to keep Appare's eccentric behavior under control. Hoping to get home, the pair enter the Trans-America Wild Race, a cross-country contest with a cash prize. Appare builds their own steam-powered car, and the two set off on a run through the wild West from Los Angeles toward New York, taking on eccentric rival racers, outlaws and the dangers of the open wilderness. Expect an action comedy with plenty of adventure on the road.
