Long ago, all humans lived in the ocean. But some who longed for the land abandoned the ocean, casting off the special raiments granted to them by the sea god to adapt them to life under the sea...
Though mankind was divided into sea dwellers and land dwellers, each with different ways of thinking, they were all still fellow humans, and they continued to maintain contact as time went on.
Sakishima Hikari, Mukaido Manaka, Hiradaira Chisaki, and Isaki Kaname live in an undersea village, while Kihara Tsumugu lives on land.
When these middle school second-year land and sea dwellers meet for the first time, their hearts begin to undulate like the tides.
The youthful fantasy tale of these young people's lives unfolds in a strange and beautiful world.

So, for some reason no one posts about it :c so I came to fix that !
It looks wonderful ( those backgrounds and those giant eyes are just so charming ) and while it seemed childish and wasn't expecting much of it, the world and story are rather interesting . It has the " drama " going on, the silly humour and that odd feeling that something dark is creeping the whole " world "( which seems to be finally kicking in now at Ep 10 )
Another pro is that it has such a nice ending song !
