actually gildarts daughte canna (i think is how you pronounce ti) she is stronger than gildarts. fairy glitter.
wrong tbh yes Cana uses fairy glitter but its not a spell that is permentaly in her arsenal it was given to her simply so she could win. but mavis gave her the spell sure but you do know that gildarts and disasmeble magic with ease give a mage a powerful spell does not make them the strongest, Meia, Ezra and Gildarts are better fighters than Cana is one powerful spell does not make you the strongest. If you have watched or read the show as far as you have you should know that.
