Empress' Report 4

Empress' Report 4 (女王の研究報告4, Joō no Kenkyū Hōkoku 4, "Queen's Research Report 4") is an Empress' Research map unlocked after clearing Empress' Report 3. Just like its predecessor, it has four stages and disappears for the rest of the day after clearing one, so it will take at least 4 days to clear the whole map. Each stage has a different one-time reward, including an Aku Catfruit Seed in stage 4. Once completed, the player will unlock Empress' Report 5, which drops another Aku Catfruit Seed.
