: The spell is eventually broken not by a counter-spell, but by Natsu's bond with Lucy. Even when everyone else has forgotten her, Natsu manages to remember her name and existence, which dispels the magic.
Fairy Tail Episode 127, titled "The Terror of Invisible Lucy," is a lighthearted filler episode that balances comedy with a surprisingly emotional core. It follows Lucy Heartfilia as she accidentally becomes invisible after using an expired magical ointment. While the situation starts as a comedic opportunity for pranks, it quickly spirals into a race against time before Lucy is forgotten by everyone she loves.
: Natsu and the others try various absurd methods to "fix" her, including Natsu attempting to "roast" the invisibility off her with his fire magic.
