Marco then said, "Up until now, I was only teaching you how to use the power of a supernova. Now that you can use it however you want, it's time for us to go to the next step."

Marco then touched the screen in front of him, and this caused the stars to disappear from the spheres.

He then threw two more spheres to each of his daughters, and said, "Now the real training begins. Before you only had to use the same number of stars that appeared on the sphere, but from now on you will need to learn to control the power of the stars."

Marco then said, "No. You were learning to use the power, not control it."

And Briny said, "Is there a difference?"

Marco then said, "Of course there is. I'll show you. Raise the spheres using your essences."

The two then did as Marco had asked, and then he said, "I'll start with a star."
