The Juukulius family also known as the "Euclius", is a noble family in Kingdom of Lugnica. The Juukulius family is known for her Knight's and the skilled swordsmen. The Juukulius family is also the only family with Spirit Knights.
Sometime in the past, the Juukulius family member, Violet Juukulius, found a spirit which a member of the Hoshin family was looking for and couldn't find. The Hoshin family then paid the Juukulius family a lot of holy coins and made them easily one of the richest families outside of Kararagi. This is also the reason why the Juukulius family is so connected with the Hoshin's.
