Unfortunately, Axel couldn't let these particles of light heal the ground because they'd be spotted straight away if they left a trail of green grass and flowers after they'd passed, so he asked Kevin and Sora: "Can you try to absorb the particles of light that are attracted to Lena like a magnet, because we're going to end up being spotted if this continues... There are more and more of them and I have to constantly reinforce my force field so that they can't get through."
Lena, who was being carried by Atlas because she was only a human after all so it was impossible for her to move as fast as them, then said: "I'm so sorry, Axel, I didn't realize they might be a problem for you, I'll take care of it!"
Lena's body then began to glow and the particles of light immediately stopped trying to pass through Axel's force field.
