The two Fleeting teams that teamed up in an attempt to defeat Luna's team had been sent out on the affected zone in utter defeat. The barren land became empty without any sign of a monster. She took that time to heal her friends, worried that the other Fleeting team would show up in a nick of time.
Their wounds and mental stress had been eliminated completely which put them on a high pedestal. Her golden flames did not simply heal physical injuries. Their team that was always at their best without any stress would be able to match up to the best seniors in Fleeting Team Battles.
They might be shorthanded but their three members were more experienced in magic combats than Luna especially close combat that involved weapons. While she was still learning, she would support them with endless healing upon the thought that she would utilize every way to defeat her enemy with a high chance of winning.
