Post-nuclear Earth is barren, and life can't survive on the surface, so the few remaining people have lived under-water waiting for their time to be able to go to the surface. Amamiku and her faithful computer guardians, Pyron and Mayzamik, guard the seeds that contain the DNA for life and re-growth on the surface when the air is breathable again, but not everyone wants that to happen.

CourScore
15.0
CourScore measures renewal signals out of 100. It is not a calibrated probability of an official sequel announcement within 18 months.
Signal coverage: 100% • Signal freshness: Medium • Updated 13 hours ago
Top reasons
- Titles like this rarely return - 25 years with no new entry: of films (first entries) in that position, under 1% got a new season or film within 10 years
- Time since finale - ~306 months since estimated air window ended
- Committee investment depth - Committee investment: 1 committee member(s)
This is an anime original, not an adaptation, so there is no source material to run down - renewal turns on sales and popularity rather than runway.
