In the game
When the player first tries to enter
Longspur's gym, there is a note on the door saying Regina's not here: she's out for a drink! After speaking to Regina at the Longspur Saloon, Regina will accept the player's challenge.

"Well, how do you do? Yours seems like a new face here in town. What brings you here to our lovely village?
...a Gym Battle you say? Well what a coincidence!
My name is Regina, and I just happen to be this town's gym leader! And I would be delighted to accept your challenge. Come and find me at the gym!"
"Alright, kid, it's not often that I get a challenger here, so I'm going to make this as official as possible!
I'm Regina, the Longspur City gym leader!
I specialize in the normal type, and while there are no obvious strengths in it, with some extra-hard work, we've learned to become stronger than anyone in this town!
Good luck, challenger. You'll need it!"
"What an intense battle!
Well, as a woman of my word, and by Pokémon League rules, it is here that I bestow upon you the Common Badge.
The Common Badge heightens the power of your Pokémon, and also allows usage of the HM Rock Smash outside of battle.
If you haven't already gotten it, you can get the HM at the Trainer School in town.
Also, take this!
That TM contains one of my favorite moves, Proud Swivel. It's a high-risk high reward move.
Please use it, and think of me when you do!"
"You're super strong, kid. You should go challenge the other gyms in the region.
Best of luck to you!"
Although she specializes in Normal-type Pokémon, she owns an Opaby (a Pure Dark-type Pokémon).
Beckett similarly owns a Pokémon that doesn't match his Gym type.
