June is signed up to attend the 'The Magical Convergence' of the year, but isn't sure about it because she feels like she isn't as good at the Te Xuan Ze job as her grandma. This section contains plot details about an episode.
But when an evil organization of magic-hating trained humans named H.A.M.(introduced as Humans for the Abolishment of Magic) by their leader breaks into the convention center and holds everybody there hostage, Ah-Mah is forced out of retirement to save the day. All monsters go there to hear her speak but are more impressed by her retired grandma. The three-day magic convention called 'the Convergence' is held every three years and June has to attend it to give a speech at this year's one.
