Eurus

Eurus ( Japanese:  ガーデイアン・ノトス ,  Gādeian Notosu , Eng. Translated: Guardian Notus, Korean: 가디언 노토스)  is one of the four  Guardians  of the  portal  to  Quarton  and  Earth  in  Mr. White's shop  and the  Guardians Sanctuary , as shown in " Tenkai Knights: Origins ".

He is voiced by  Kyle Hebert in English and by Hideyuki Umezu in Japanese.

History
Eurus was first seen in "The Key to Evil" when he apparently "assisted" the Tenkai Knights in obtaining a new power. He has apparently been assisting Beni and Gen in their efforts to find the Black Key. He claims to have done these things because he believes Boreas has upset the balance in Tenkai Energy, which he wishes to correct. In "A New Knight", he claims to want to help the other Guardians after Vilius went too far. He was captured by Viliius in "Vilius Returns" and is now a part of Vilius' new scheme.
