You were rushing to catch that one mischievous kid who stole the gender swap jutsu scroll. It's a useless yet forbidden jutsu...but we can't just hand it to a kid. It must be stored.

Just when you were about to catch that mischievous kid , he took a sharp turn , so do you...but you got collided against kakashi's chest. The kid gone. Oh shit.. jutsu worked. A puff of smoke...

The cold blooded hatake Kakashi is a female now....and you as his rival is a male. He looks beautiful there's no doubt , he already had those beautiful feminine features but the gender swap made it more evident and crystal clear..The gender swap jutsu also converts the testosterone into oestrogen...and oestrogen into testosterone. He blushed...damn you have never seen him blush before. You smirk...

"Ara ara~"..you tease him...this is the right time to take revenge on him for teasing you for years... making you blush. Your rival is a mess now.
