   Summary

   Tracen Academy is having guests from overseas visit to see how they train compared to elsewhere.

   Nice Nature and Marvelous Sunday see the announcement, and using her MARVELOUS~! ☆ energy, she hopes they find Tracen welcoming and that they can belong.

   For one said visitor, that means they get magically Horsefem'd while taking a nap.

   Surely this will turn out fine.
