Here is the proof that LDK scoring system is the same as Son of Sparda: Hard | Devil Hunter | Son of Sparda | Dante Must Die S Rank Time and Style Requirements (LDK is set to Son of Sparda difficulty) These are the same on all difficulties and represent the points you are given for clearing each mission. Total points = (Clear Bonus + Style Points) x Clear Time x Orbs Found x Bonus & Penalty x Difficulty The points required to get an S Ranking for every mission are calculated as follows:

Heaven or Hell mode and Hell and Hell mode doesn't require S Ranking. Human mode is the hardest since most of the missions requires 100% Red Orbs found and a no damage bonus to get S Ranking.

I made this guide to help players know the requirements for clearing every mission with an S Ranking.
