Emperor Deity

 'Emperor Deity (皇帝神 Kōtei-shin or Kōtei Kami in some instances) is a series of cards used by major characters in Yu-Gi-Oh! ReWrite. They are essentially the "Gods" of their respective Attributes. Each one of the Emperor Deities is of a different Attribute and a different Summon type. At the start of "ReWrite", there are supposedly six Emperor Deities in the world, however, Yuzuki Taiga creates a seventh one, Time Emperor Deity - Chronos Dragon.
