The First Day

Luz attends her first day at Hexside, but has trouble deciding what track to enroll in, so Principal Bump places her in the potions track. When Luz gets caught using a crystal ball used by oracle magic students, she is placed in the detention track. Meanwhile, King follows Luz to school and takes over a class. Wanting to escape detention, Luz is brought by her fellow classmates, Viney, Jerbo, and Barkus, to a secret shortcuts room created by "Lord Calamity", which they use to listen in on other classes and learn mixed magic. They become offended after learning Luz had said that she was better than them and make her leave. Meanwhile, a visiting school inspector turns out to be an impostor and a magic-draining Greater Basilisk. Luz asks the detentioners for their help to defeat it, and they use their mixed magic skills to subdue the beast. Luz convinces Bump to allow them all to learn mixed magic. Bump reveals that the only other student who wanted to learn mixed magic was Eda, revealed to be "Lord Calamity", but never got to. Later, Bump finds King posing as a teacher and chases him out of the school. (Source: Wikipedia)
