It was a good thing that Yukina found that pun rather funny. For a moment, she giggled before nodding to herself.

"I'm not! I thought that going to class to learn about the human body was a little boring. That's why I said it since I thought humans would like that kind of activity."

After all, it does sound like something Shizuru would say. To take a leap of faith and have some balls, right? She wasn't quite sure what that means but it might have something to do with having some courage!

"To be honest, I'm not sure if I'm that adventurous. Maybe Hiei or Yusuke might do it."
