This trophy is essentially getting each of the other S rank trophies. They are as follows...
"The Nine Tails' Attack"
"The Agitated Five Kage Summit"
"Hero and Avenger"
"Overcoming Hatred"
"The Seven Swordsman"
"The Rumbling Coast"
"Bet the Future"
"The Last Battle"
Warning: IF YOU HAVE THE DLC, YOU WILL NEED TO BEAT THAT BOSS WITH THE S RANK IN ORDER TO GET THIS TROPHY. Many people say this isn't the case, but I personally can attest to the fact that this is the case.
Generic tips for S ranks...
Health is a big part of the ranking system. It's pretty much the key statistic.
In stages with mob battles, you'll want to defeat a few extra enemies that you wouldn't normally have to. This is because you get credit for particular milestones like 30 and 50 enemies defeated and for landing so many back attacks. The back attacks are when you defeat an enemy with a melee stream and then tap "X" to end up behind another enemy. I'd suggested getting a few extra kills, just to bolster this rank. This is particularly true in "The Seven Swordsman" because if you don't go out of your way to defeat extra zetsu while on the Her path, you won't get the S rank.
Stars Collected in the quick time events are also a big part of it. You'll want to do your best to get as many as you can. They also help restore your health, making the S ranks easier.
