Hiyori's Soul Call.
The Soul Call is a summoning technique that can only be used by living humans, and is known to be the only way for someone to escape the Underworld. One's name acts as a tether between the Near Shore and the Far Shore; therefore, by speaking a person's true name, they are able to forcibly pull them from the underworld. The Soul Call does not work with nicknames or aliases, as shown by how Yato could only be removed using his true given name, Yaboku.[1]
It seems that this ability is not common knowledge amongst gods. Kofuku was only informed of it by Amaterasu, and neither Yato nor Bishamonten were aware of its existence.
Usages
- An unnamed freckled woman used it on Father.[1]
- Hiyori Iki used it on Bishamonten and Yato.[1][2]
- Kouto Fujisaki used it on Nora, although it is unclear which or her names was considered her true one.[1]
