Nobunaga Teacher`s Young Bride

"Nobunaga Teacher's Young Bride" (Japanese: ノブナガ先生の幼な妻, Hepburn: Nobunaga Sensei no Osanazuma) is a Japanese romantic comedy manga series by Azure Konno. It was serialized in Futabasha's seinen manga magazine Monthly Action from May 2017 to August 2019, and was collected in five tankōbon volumes. An anime television series adaptation by Seven aired from April to June 2019. The story revolves around Nobunaga Oda, a middle school teacher who dreams of a gal game-like situation. However, his life takes a turn when Kichou Saitou, a 14-year-old girl claiming to be his wife, appears before him. Having apparently traveled from the Sengoku era, she mistakes Nobunaga for the historical Oda Nobunaga and urges him to have a child with her. Thus begins an age-gap romantic comedy between a teacher who loves gal games and a princess from the Sengoku era. The anime's opening theme is "Aiseyo Minna, Hai!" by Pyxis, and the ending theme is "Returner Butterfly" by Rika Tachibana.
