A high school kid replaces history's most famous warlord, then the show immediately forgets the time travel hook and just tells you who Nobunaga actually was. The art style looks deliberately unfinished at first, all rough linework and color bleeding, but it becomes the only visual language that could carry this much personality without drowning it in spectacle. The soundtrack doesn't score moments, it becomes the emotional weather of the entire era.

Saburou is a carefree high school student who shrugs off Japanese history as irrelevant to his life, until he is suddenly thrown back to the Sengoku era. He lands right in front of Nobunaga Oda, the famous general, who is fleeing his retainers and too frail to carry on. Because the two look almost identical, Nobunaga begs Saburou to take his place, hands over the items that prove his identity, and slips away. Still bewildered, Saburou begins posing as the warlord who set out to unite Japan, relying on his modern knowledge to get by. The series is a comedy with romantic elements.
