If I ever become able to make stuff for this game, here's what I'd make 1. Flandre outfit, Including weapon. 2. Persona 4 weaponry, who wouldn't like beating crabs with a golf club, monkey wrench or folding chair? 3. Teddie Outfit. 4. My own enemy?
How about when you get an achievement you get a set amount of gems, Like 1 for the basic ones, 5 for the Easy ones, 10 for the moderate ones, and so forth
