Saburou

Saburou is a high school student who has no interest in Japanese history until he is suddenly transported back to the Sengoku Era. After meeting the legendary Oda Nobunaga, he is forced to impersonate the warlord because of their striking physical resemblance. To survive the era's political instability and ensure history unfolds as it should, he uses his modern history textbook as a guide through the period's turbulent events.
