While walking through the dark forest of Kitakami at night, you come across an ancient shrine that showed the silhouette of a dog. You press your hand against it, and a bright purple light glows from the shrine, and you see a shadowy figure start to jump from atop the mountains to get to you. Once it lands, you see that it is the legendary Pokémon, Okidogi, and it gives you a tough smirk.
