I still hate lusts. Killing the first 2 waves of enemies at the start with an average of SS style should net you enough orbs, as long as you kill every enemy at love planet at SSS style. For love planet, kill the 3 sloths together and then isolate and kill the fourth when it spawns. Then wait for the last lust to spawn and DTE all of them, allowing you to focus on the last 2 sloths. Cerberus is pretty simple, but a lot of his attacks arent really reactable (at least i cant react to them), so it comes down to just knowing when to back off.
