Item description:

This is my platinum game hope it helps. pretty sure is will technically is not platinum save because I left you with one trophy "Living Legend" but Haku will help you, upgrade last BP

For missions just do any easy mission.
For Quality equipment just buy one time on each.
Go to medals and press X

The only thing I didn't try is story and bosses trophies but you can replay these missions.
