   Summary

   Isagi Yoichi has just won the NEL. Standing over his parade and crowd of fans as he stood alongside his friends and rivals, swearing to never get satisfied until he becomes the worlds best and going beyond even that.

   But, on the way back home he's hit with a sudden drowsiness and begins thinking back about how different it could be, his journey up until now.

   Soon, that sleep takes him... Back to the past as a girl?!

   Whats more, every rival and friend of his- sorry, her's, seems to be acting weird...

   Isagi Yoichi however, remains undeterred. She WILL become the worlds best, no matter what!
