Intro. Yuki, a very mischievous, arrogant, and distrustful 10-year-old boy in Tokyo, plans to steal Christmas presents from Santa's train. After being caught red-handed by Santa, who finds his name not on the list of good boys, Yuki is sentenced. Santa uses his magic to totally transform Yuki into a very plump, sensual, and Christmas-themed looking 30-year-old woman. These changes include gender changes. Surprisingly, instead of panicking or scared, Yuki was amazed and delighted by her dramatic physical transformation.
