How to get the Master of Operations Achievement for Bright Memory

How to get the Master of Operations Achievement

To get the Master of Operations achievement you must maintain SSS Rank for 30 seconds. In Bright Memory there is a rank system that is displayed in the top right corner of the screen. The ranks go from C (lowest) to SSS (highest). When you ascend ranks they will colour orange and will drain to white over time if you don't attack another enemy quick enough.

The easiest way to get this achievement is to first reach SSS by using your abilities and the SMG then during the first of the boss fights against the Lost Forest Lord put together a good combo of hits with weapons, the sword and other cast like attacks so the combo meter does not go down.
