You know that Japanese Shinto religion is one of the old branches of Animism, and vary in deities due to its feature.

That Takemikazuchi the 6-legged tank I mentioned for times was name after a god of thunder/sword 建御雷(Yeah, Takemikazuchi)

Name a name of a deity from a certain mythology

This deity is shaped as regular human, but doesn't have arms.

White is considered as the color theme of the appearance

Information aboout it is very few...... maybe Bill Cipher should count as a hint.(STOP!)
