Where are the move tutors?

Question

I managed to find most of the move tutors on OR/AS but I can't seem to find the ones for secret sword and relic song on here.

Answer 1

>In the south-western part of Mauville City is a small café. Within this café, you will find this character who will teach moves to two specific Pokémon. He will teach Secret Sword to Keldeo, causing it to instantly change form, or Relic Song to Meloetta.

There you go, the move tutor for Relic Song and Secret Sword is in Mauville City.
