I'm in Free! Iwatobi Swim Club?

You walked into your room with your laptop. Your parents were going on a business trip all week and just left a few minutes ago. Sure you had a whole lot of stuff to do around the house, but surely you could wait until tomorrow. Or the day after. Or the day their supposed to come back. You logged into crunchy roll and decided to rewatch Free! Iwatobi Swim Club for the tenth time. Its not your fault they animated those abs so well. You just so happened to be wearing a dolphin t-shirt that Haruka would just adore! You smiled, wishing you could meet him and all the other characters. Oh well, fangirling will have to do for now. As the browser loaded, it suddenly went black and you watched as Gou appeared. She waved, "Hi there (name)! I see you love our world!" You jumped back in surprise and screamed. "Hey hey calm down! It's okay!!" You crawled back to where the laptop sat on your bed and said, "How is this possible?" She beamed as she explained, "In every anime, there is one character who can connect with your world and with other animes. I represent Free!. And I think you could help us out!" Still in shock, you replied, "But why me?" "Well (name), Rei is injured and we need someone to fill in for the competition this Saturday! And you are the perfect girl for the job!" You scratched your head. Sure you Swam competitively since you were five, and sure you were best at butterfly, "But isn't it a guys only competition? I couldn't compete even if I wanted to." Gou just waved her finger. "I can fix that. So will you help?" You sighed. Not like you planned on doing those chores anytime soon. So you nodded and the next thing you knew you were being sucked into your laptop. You squeezed your eyes shut until everything stopped. You felt someone poking your cheek. "Hey (name). It's over now." It was Gou. You laughed, but stopped dead when you heard your voice. That wasn't my voice... you ran to a nearby window and almost screamed.

You weren't a girl anymore. Because Gou had turned you into a guy.
