I can't play PoFV on this computer so I can't exactly watch the replay, but there are a few things you need to know about PoFV.
1. L2 bombs are god tier. HOWEVER, against the AI you need to realize that also means that with the eventual bullet barrages L2 bombspam puts forth your opponent will have near-constant deathbomb fuel. Still use L2 bombs, but when fighting the AI use them in moderation, and back off if things get too hectic.
2. The odds of the AI being hit are completely proportionate to speed and walls. Slow opponents and fast bullets will increase your chances of landing hits. They also really can't do anything if they're walled aside from bomb, though that kind of applies regardless. Also dealing with landing hits, the AI only looks at things with a collision box, meaning bullet/EX spawn areas and Lily White herself won't register at all, which can lead to a few stupid deaths on its part.
3. Don't use Mystia or Lyrica if you're actually trying to win.
4. Aya is all streaming. If you go into that fight trying to dodge everything by flying all over you're going to die, and fast.
There are a few other tips that I usually give out, but I'm not thinking too clearly at the moment.
