Speed run advice Options

[Mr_HipHop]

Hey guys, I really love riviera since i was young but i haven't completely collect every items and endings so i decided to devote myself again into this game. However, i don't have a lot of time and i only got 1 ending with Fia
Therefore i would like to ask for advice about how to finish Riviera in the shortest amount of time possible?

P.s: Thanks for your help. You guys may also share a little bit of your experience playing Riviera as well and i'll share some of mine.

I tried doing an actual speed run of Riviera a while back.
It was rough. Really rough.
Best advice: use Fia/Lina for their high-hit-count items to build your bar, Serene/Cierra to unleash hell, and Ein for support items/Einherjar if you need a last-ditch S-Rank. ALWAYS S-Rank. It doesn't have to be pretty but if you don't you're not going to have the item supply. Stupidly, Riviera punishes you by upping the difficulty if you perform poorly (by reducing item access).
Ignore items that your characters aren't going to get overdrives, high hit counts, or healing/buffing/nerfing skills from, OR be able to trade/interact with for better items/the ones you need to complete your collection.
Don't use the two female characters you're not going to use for the above purposes at all, BUT go for one of their endings.
