Ranma, at the request of his mother, must now become a girl among girls!
Nodoka has come to a conclusion. Her son has become a Man amongst Men, but now it's time for her to become a Woman amongst Women as well! So starts the Girl Days training program. Ranma must remain a girl for the next 2 months, and thereafter at least 1 day in 4. How on earth will she survive...
Ranma's mother came up with the idea to help Ranma understand "femininity with masculine determination" since he's both a female and male. So now Ranma have a stay as a girl for a while.
