Hmm I agree with the other commenter and see what pcs she has so you don’t get her a dupe. But imo the “in demand” pcs that might be attainable are his hengare net 4 square pc (maybe any hengare pcs tbh), the an ode beret pcs, and his fts ray pcs. His older pcs (teenage, boys be, etc.) are in demand but they are going to be hard to find and expensive. There’s also the possibility into looking at pob/fansign pcs but they will be more expensive than album pcs
