Played on Furier difficulty. The good thing is you don't need to get S rank for every boss to get an overall S rank for the story mode. Also you do not need to fight The Star.
The overall S rank is based on
1) Overall Clear time
2) Number of KOs
3) Number of times you got hit
Just pick 5 or 6 bosses and do well on them and you should be fine getting an overall S rank for story mode.
00:19 - The Chain S Rank
05:18 - The Strap S Rank
13:26 - The Line S Rank
20:08 - The Scale S Rank
28:02 - The Hand S Rank
35:26 - The Song A Rank. Made stupid mistakes here. From here on, I don't really bother much with S. It should be quite comfortable getting an overall S from here on.
42:06 - The Burst D Rank. Fucking hate this bitch. Is she here to fight or to play hide and seek?
56:57 - The Edge S Rank.
59:45 - The Beat D Rank. I just want to rush through this shit and get it over with.
