Paradise Residence chapter 19 and Paradise Residence Zero released

How to save the dorm?

Sorry for the delay, but here's the next chapter. With their first attempt a failure, how will the girls save their dorm now?
Not only that, we are also releasing Paradise Residence Zero, the compilation of the short manga chapters that had been released years prior to the series going regular.
Paradise Residence Zero is based on the retail edition of the volume. Many panels have been redrawn. Highlights are: Screentones have been made denser, more visible, and added to several previously blank areas. The dorm interior and exterior have been redrawn. Hatsune and Suzuka now have watches on their wrists.
