Technique of Forefathers: Primordial Immersion

This jutsu is a technique used only by the crocodile Gyrawani. In any water source, it allows the user to sink into an empty ocean, where noone else can follow unless they were touching the user when it was activated. If you go up in this ocean, it leads to the lake in Waninumakakou, and you can only return by using the technique again.
