Case Number 04: If Pu were not so Ambiguous...

Obviously Male:
Nothing worth reporting. The show and manga would press on normally.

Obviously Female:
Can you even begin to imagine what Yusuke would go through? He wouldn't be able to walk in and out of a room without one of his friends (or enemies) mentioning his inner woman.

"I bet I could make that chick sing a different tune, if you know what I mean."

In fact, they would start wondering if he really was a he. Yusuke would get so sick of the constant mocking he might just-

"Yes! I'm really a transman! Goddammit Kuwabara!"

"I knew it!"
