The beautiful blue sky, the vast blue sea. A tiny boat in crystal clear ocean. The sea witch Wadanohara, along with her familiars, is returning to her underwater hometown after a long time away. But before her looms her first familiar, Samekichi.
"You... Get away from this sea right now. You should not be here..."
Oounabara to Wadanohara was digitally simulpub in English as Wadanohara and the Great Blue Sea by Seven Seas Entertainment, and in Chinese (大海原与大海原) one month behind the Japanese version. Seven Seas Entertainment plans to release the series in a single omnibus on July 4, 2017.
