Grachi

The season centers on Grachi (Isabella Castillo), a witch and a new student in Escolarium. She deals with using her magic and trying to find out how to defeat the Principal (an evil witch who tries to steal the powers of Grachi so she can be the most powerful witch). Grachi also deals with her rival, Matilda (Kimberly Dos Ramos) with whom she fights for the love of Daniel (Andrés Mercado). At the end of the season, Matilda celebrates her 16th birthday at the night of the eclipse while the Principal (Martha Pabon) and Sibilo (William Valdes) plan to steal the powers of Matilda and Grachi. The two girls team up and fight the Principal, turning her into a dog, but losing their powers. Matilda finally realizes that Grachi and Daniel are meant to be together.

A dark witch, Mía Novoa (Maria Gabriela de Faria), who uses her power to do bad, enrolls in Escolarium. Mía is in love with Daniel and Grachi will do anything to fight for their love. Also, a geek named Leo falls in love with Grachi. On the other hand, Matilda starts dating Diego, a Kanay whom she has an on and off relationship due to Matilda's obsession with her powers and her witch instincts. At the end of the season, Grachi and Matilda's parents get married, thus making them stepsisters. Also, both witches teamed up to protect the wedding from an angered Leo, Mía, and Athena, a witch in love with Grachi's father Francisco. Also, with the exception of Daniel and Mecha, Grachi and Matilda erases everyone's memories about the events that happened, including Mía.

Grachi enrolls in the School of Magic, where she meets a new love-interest and main antagonist, Axel, a mischievous kanay.
