As noticed by Rent-a-Girlfriend manga creator Reiji Miyajima, his creation, along with Fire Force, are two of the most popular works on Netflix right now.
Checking Netflix Japan ourselves, we can confirm that Fire Force is taking the number one slot, and Rent-a-Girlfriend is at number four with only two K-dramas in between them.
Fire Force, Rent-a-Girlfriend, and Natsume Yujin-cho are all available on Crunchyroll to watch right now, with the last episode of Rent-a-Girlfriend to air this Friday.
