A little question,we all know esther is a really hard boss and we all know s ranking her is harder so do you think a sub -50 seconds S Rank is possible on her?

You are fairly close. I believe so. I'm not sure how much better divine relic's 30% stronger coffee is, for as you can only earn cards from parries after 6 times, and you cannot luigi swap, which I think would worth it for you to learn considering how many EXs you use in your current strategy.
