Mystery of Nonomura Hospital is a two episode, 30 minute each OVA based on the erotic game Nonomura Byōin no Hitobito by Silky’s. The hanime was released in 1996. The game came out in 1994.
Takumaro Kaibara: brilliant detective, daring adventurer, AND TOTAL PERVERT! There’s no crime he can’t solve, and no skirt he won’t chase in the name of justice! So when Takumaro lands a case at Nonomura Hospital (famous for its hot nurses), it seems like a match made in Heaven. Now somewhere between his busy schedule of pick-up lines and peeking at the nurses’ panties, Takumaro must uncover the truth behind the death of the hospital’s president. Was it really a suicide or was it cold-blooded murder? The nurses aren’t talking and everyone seems to be hiding something. But Takumaro isn’t worried – his biggest challenge is to make it with that cute redhead, or die trying! And all he needs to do for himself and the case is to feel his way through every girl’s panties.
A combination of the goofiness with his sexual harassment and the detective work. The art style is okay, but better detailed bodies during sex scenes. The animation is fine and the plot is interesting. There are only two fuck scenes in the first episode, less than 5min long in total. For Mystery of Nonomura Hospital/Nonomura Byōin no Hitobito I found one DVD. And there’s always the streaming service.
