==Guide==
Go to Grand Hall and cover the expense of the Azurine Nature Center Project.
Then go to Grand Hall Basement and go to the path on the top right corner. Talk to the guy on the left to start the quest.
Go to the new Nature Center and talk to the woman on the left side on the base floor. She will ask you to bring her two Simisage, 1 Male 1 Female, and two Lurantis, 1 Male 1 Female.
Simisage is not available in the wild until the middle of Postgame, so it's easier to find its pre-evolution Pansage and evolve it. Pansage can be found in Malchous Forest Park, Beryl Ward, Rhodochrine Jungle, North Aventurine Woods, South Aventurine Woods. Lurantis can only be found in Malchous Forest Park.
After you have obtained the required Pokemon, give them to the woman. Then return to the guy you talked to earlier in Grand Hall Basement to receive the reward.
