A Tree of Eris's Hope (Circu Series #1)

"I want to be the strongest wizard! Just like Discordia-the last wizard standing who defeated thousands of demons!"

Eris Hecate Discordia is the strongest wizard ever known on planet Eterna. Not only is she powerful, but her magic is also so unique that no one can replicate it. Her heroic tales have been passed down from generation to generation and are admired by countless magic users. But when she returns to Eterna after many years to search for a friend she left behind, she encounters a wizard using 'Sigwa', her most powerful magic spell!

However, the spell is a failure.

Eris's true reason for returning to Eterna is to find her friend, but she ends up training a young wizard, the son of the King of Hiraya, for his upcoming wizard ranking competition.
