After some time has passed in Chapter 3, return to Iyama for a cutscene. Afterwards, you’ll receive the Extracting the Truth side case. This time Iyama will need roses! You can purchase a rose for 1,280 Y at Flowers 2 Go, which is in Hamakita Park. Return to Iyama to hand over the materials, and you’ll receive an Extract Recipe: Willow Snake. He’ll then want garlic! You can find it from a resource point at Hamakita Park or save yourself the hassle and purchase it from Hero’s Harvest in Hamakita Park for 598 Y. When you hand it over, you’ll receive the Extract Recipe: Rushing Tiger! Next up is a four leaf clover. We obtained ours from a resource point in the grass at Hamakita Park! Alternatively, you can purchase it from Flowers 2 Go for 5,000 Y. Once you’ve found one, hand it over to receive Extract Recipe: Dancing Crane. A cutscene will ensue and the case will close.
