Last week, the heroes of Edens Zero spent their first day on the planet of Red Cave with a good old-fashioned beach day. However, that soon got interrupted by the sight of a space pod crashing into the ocean. One trip to the bottom of the sea later, and they find the pilot of said pod to be long dead. However, what’s even stranger is the fact that there’s an entire city underwater! How did this city get here? What connection does it have to Mother? And who is this Nadia person that’s referenced in the title of this chapter? At least one of those questions gets answered in this new chapter of Edens Zero.
