Once again, it was a ordinary day for everyone in Kadic. Yumi, who had been put down a year for secret reasons, was with the rest of the gang doing Gym. Everyone now new of Yumi's powers, and she was stronger than ever. That was, unless it was to do with running. She was never good at running.
"Ishiyama go faster!" Jim encoraged Yumi. She was doing a 500 metre run. Just as she was nearing 50 metre's away from the finish line, Jeremie's laptop started beeping from his bag. XANA had activated a tower.
Yumi had soon finished the 500 Metre run and when she got told that XANA had an activated tower to deactivate, she said she'd just stay on Earth, and she'd protect Earth if anything bad happened. Then, with an excuse (Jim, can we go to the infirmary? We all have massive migranes.) Jeremie, Odd, Ulrich and Aelita set off to deactivate the tower on lyoko.
XANA didn't seem to be attacking Earth at first. However, during the next period, which was Science with Mrs Hurtz, screams could be heard coming down the hallway. "Great..." Yumi thought "I'm going to have to fight XANA." Everyone looked out the door, including Yumi. Other students, including Hiroki, were running away from Jim. He was XANAfied.
"Yumi, can you do something about this?" Sissi asked. She was being awfully nice since Yumi was discovered as a fairy. Yumi then transformed.
What Yumi's transformation looks like
She is in the fetal position when wires come and cover up her (clothed) body. The wires then turn into energy, taking Yumi with it. She then rises from the bottom of the screen, clicks her fingers and her Winx outfit (Which was just Energy before) forms it's shape.
"Musical Boom!" Yumi exclamed. The battle had bugun.
