Child of Eden: Lumi's Garden (All level three rewards on each Archive)

Every time you complete an archive (except the Hope archive) you can get one of four rewards for Lumi's Garden, which is basically a hub world here. It's pretty much an attraction to make her garden look fancy and really beautiful, and you can upgrade the reward to really stand out. It's all fun and games until you realize you have to complete each of the five archives TWELVE TIMES to complete the archived garden. Yes, twelve times, and these archives are around ten to twenty minutes to complete. I don't really mind replaying them over again but man it was tedious.
