Manager Kuromi will help you unlock various shop decorations. There are many Sanrio characters, and you can do synthesis multiple times. If you don't have enough stamina, don't rush to buy it. First, check out the rewards from various activities. Some of them give stamina as a reward. I took on time-limited missions and a hidden mission. I've completed 3 time-limited missions so far. I remember one gave over 20,000 gems, and the other two gave over 2,000 gems. The hidden mission gives over 20,000 gems for reaching level 15 and level 20 respectively, which is quite good. I'm only level 13 right now, and I only have 2 days left for the missions, so I need to hurry!!!
