As the first one

Cy had in mind good far away location to visit via teleportation-Yume Academy. Made some friends there from her visits-Wraith, Phoenix, Estel, Capsu girl, Succuba and Kong Ming. They will be happy to see her visit them and have a good talk about both schools. The other school sheduled even naked sport day activities some weeks later.

Preparing the sword ,Cy carefully swinged it,making hole just big enough to get in. She felt again as a feather in the wind and braced her for any impact in the exit. Few couples of second later she exited in the Yume stadium. In front of her stood the balls, the grass field, the doors, which would be guarded in socker match. A bit resembling the stadium in the ninja school, but with much more lights on.

Nobody was present at that moment moment in the sport field. Otherwise there would be a witness for appearing of a naked confused girl amidst the grass. Cy observed the scenery around her and then she came to the same realisation-her clothes were lost again.

Worring little about been seen and more about losing another suit, she reluctantly swong the sword again to go back. When the second teleporting attemt concluded by her on the sport field of Mizaki school, she thought about her options for continue.

Basically,they were several.

1. Going for another suit and abandoning these teleportation expeiments.
2. Going for another suit and continue them.
3. Continue them naked.
4. Continue naked with a plan.
