Noi is the familiar of Amamiya Yuuhii, the Lizard Knight. Noi is a rather logical being and believes it is his and Yuuhi's duty to protect the Princess and defeat the Mage's plot to destroy the Earth. He becomes aware of the plans of Yuuhi and Samidare (the Princess) and is rather disappointed in Yuuhi's attitude towards the struggle between the Animal Knights and the Mage. Noi is quite knowledge about the other Animal Knights (although he does not know their human-counterparts), the Mage, and other various details of the struggle. Can only travel a short distance from Yuuhi before being teleported back to his side. Can't be seen by regular humans.
