Hitorigami (独神)

Hitorigami is a Shinto deity which came into being not in pairs but alone. Generally, those gods who have parents are not called this way.

In contrast, a pair of male and female deities are occasionally called 'Narabigami.'

Another examples similar to this are 'Tomoni narimaseru kami' and 'Tagui narimaseru kami' (kami which came into being in pairs).
