Mushi-Shi S01 E22 Shrine in the Sea

"The cycle of life extends beyond the world we can see and connect us all in unexpected ways."

"Give birth to me once more. I want to meet you once more. I want to see this beautiful ocean once more..." Ginko arrives on an island asking about the so called "Rebirths" but to no luck. At night he later meets a peculiar lady who happens to be able to see a strange light in the sea and she ends up inviting him to her home. She later explains to him what "Rebirths" are; when a person is about to die they can be taken deep inside the Ryuugu, where they are reborn.
