Move forward, getting onto new shelves with Angel Boost and Angel Lift. Stop when you reach a new rock and destroy it with an Arbiter. After a few cut scenes you'll get a new offensive skill, Devil Trigger, thanks to which Dante gets stronger and enemies are helpless for few moments.
Of course, game will immediately let you test Devil Trigger, helping you with suggestions. Observe a bar of its power. I recommend to activate this skill only when the bar is full, because its duration is limited. Use Devil Trigger on the first group of monsters. According to the game's hint the best is to damage monsters in the air, because it gives more points.
Probably you won't finish them off with active Devil Trigger, so end the battle. After a moment this sequence ends.
