Shadow on the Moon

Anyone who could construct a stable Spell Model could become a Wizard — that was the Wizards' ultimate secret! Having been given a new life as the son of an aristocrat and armed with a super quantum computer from his past life, Spell Models game as easily as breathing to Merlin. With this overwhelmingly huge advantage, would Merlin become the greatest Grand Wizard of all time?

A Wizard's Secret

J_Squared

Blessed with a wild power, the force of Taran City swelled up frenziedly. Traces of mysterious energy were bestowed upon Wizard Finello. From a distance, the entire Taran City seemed to have turned into an ocean of fire, flooded with a firestorm of horrifying force.

Two figures sprinted from afar and stopped at Taran City. They were the two ugly Wizards.

However, when they saw the frightening state of Taran City, their faces revealed how aghast they were.

"Damn it, Finello has summoned the full strength of the Modoya Magic Circle! The Modoya Magic Circle is a Runic Magic Circle that Finello unexpectedly obtained. Setting it up is a complicated process, but once it's done, it'll gather the powers of all Spell Casters within the Runic Magic Circle and control all Elements. All of these forces will be bestowed upon the user, and his powers will increase by many times over instantly."
