Healing Seaspray (Japanese: いやしのしぶき,Iyashi no Shibuki)
Otohime is based on the sea goddess of the same name, also known as Toyotama-hime (豊玉姫): she is the daughter of Watatsumi and queen of the Ryūgū undersea palace (see Mermaidyn#Origin). After marrying the fisherman god Hoori she gave birth to the god Ugayafukiaezu, who would then be the father of Jinmu, Japan's first emperor. Most famously, she appears in the Urashima Tarō fairytale, and her true form is said to be either that of a sea dragon or a crocodile.
As Otohime is exclusive to Yo-kai Watch 3: Sushi, all of the Yo-kai needed to break her seal are all exclusive to Sushi.
