Nobunaga-sensei no Osanazuma / Nobunaga's Young Bride [Fanservice anime]

"Nobunaga-sensei no Osanazuma" is a regular fan-service anime series. Not hentai! Like other anime series, it is added for the collection and may later be converted into a full compilation after the fully uncensored BD version is released. 

"“One day, a girl who is in love with me will suddenly appear before me and confess her feelings,” — middle school teacher Nobunaga always dreamed of such a crazy situation typical of dating sims he knows so well. However, the one who appears before the hero is Kichou Saito, a fourteen-year-old girl who instantly declares herself his wife. And all because, having arrived from the Sengoku era, she mistakes Nobunaga for Oda Nobunaga! Not only that, she urgently needs to conceive his child...

Thus begins a romantic comedy between a teacher who loves shoujo games and a young princess who is an expert in the Sengoku era."
