As I posted earlier, I've been using a Google Translated version of
this Japanese guide for Magical Girl Monomi. Those items are in the order that they appear in the equipment list. I'm missing two items, that supposedly appear on Normal. It's worth noting that I've gotten all of these on Easy or Normal so so far nothing has been restricted to Hard mode. Here's my totally slapdash list that I've been updating with the English names of things as I've collected them. The X just means I've collected it. English names are in caps. Google Translated names are not.

As you can see, I'm missing whatever is between Gold Rush and Vanquish, as well as Swallowtail. I've played those levels on normal 4 or 5 times each. Going to give Hard a try just to see what happens.
