The stone has a peculiar shape, similar to two parallel rods connected by a central bridge, forming something that resembles the letter "H".

It is located at the bottom of Amagafuchi. ^[2] It is protected by a serpent named Rintaro. ^[3]

In the serpent clan, only the reincarnation of the Water God could use it.
