Deep-Sea's Rainbow

Shinkai no Niji

XReddit
The idea is a myth of the deep-sea. A sperm whale swallows the sun and swims toward the deep-sea. A giant squid inherits the sunshine. Thousands of squid babies are born like shining stars. Love beyond Species in the deep-sea. A rainbow appears in a moonlit night. A giant squid finishes laying eggs and bids farewell to her own life. A sperm whale feels the rhythm of the universe with the sun as usual.
