Was there an anime made from light novels like the R-15 Lost Housekeeper? Something like the R-15

Answer 1

R-15 was a manga created by the Japanese manga artist Amagatsu, while the Lost Housekeeper was a light novel. There were some works that were adapted from light novels into anime, such as Evil Crown, About My Reincarnation as a Slime, Sword Art Domain, and so on. These works usually had excellent storylines and characters that were loved by the audience. However, due to copyright and review, the animation process of these works may be more complicated.
