(I'll just finish up this competition, don't worry, this stuff happened before the training mission, if you're confused).
Rita gets weary as the ninjas she wiped out and saw as they wiped out each other, got lesser and lesser. The final, remaining fighters were left as they and Rita engage in a final attempt to win this war.
The katana's barrage in a dancing sword play, however Rita was easily wiped out by the two ninjas, whoever obviously stronger and quicker than her. "They're too strong," She panics, trying to dash away as one of them sends cloth to wrap against her foot, as Rita cut the cloth, it was too late and katana "impaled" her.
Thanks to the barriers Master Loheart set up, she was sent out of the dome in loss... Dawn struck and she sat at the tree, looking at the sunset that was just above the horizon line, where the magic school was. "I'll be fine," She grins, cutting her hand with a kunai knife. "I vow to get stronger."
Back in the forest, there was a mysterious figure that decapitated both ninjas stood remaining. People thought it was fake, as they suffered the same affect from this competition, even so this time, it was real. All the previous deaths were stopped by Loheart, but these two ninjas heads were cut clean off... that also should've been stopped by Loheart's barrier. The ninjas were dead and the school shut down the certain forest area to investigate.
~The end~
