Hi-Fi RUSH

To make it a little easier to knock out S rank, you can replay battles as soon as the battle is over and scoring has begun, if you see that there are not enough points (minimum 2s and 1a), then pause - refuge - continue, you will be loaded before the battle

For farming style points for rank s during combat, the special moves "Hibiki" (if you know there will be many enemies in the arena) and "cute 808", which is the most expensive and last special move, are ideal. But successful use, especially the latter, almost guaranteed to raise the style rating to s, pouring out 60-80k points.

Well, for the second slot I recommend a saving sip, so as not to accidentally move away and not replay the chapter again, since for the s rating it is allowed to die only ONCE per composition.
