Pollinic Girls Attack! - Season 1

Based on the manga by Koume Keito. An alternate reality exists where sex is not a private or distinct concept. This condition stems from pollinic humanoids, beings of both female and male types. These entities travel through the air like pollen. Upon encountering a receptive human, they initiate a process intended for fertilization. Their presence is commonplace and constant during their seasonal period. Effective methods of avoidance are scarce, resulting in nearly the entire population being affected by what is termed the pollinic humanoids' mating allergy.
