Blue is a girl

Given the way she liked to act and dress, it was often a challenge to remember that the rival you spent most of your life growing up with was in fact, a girl. Her long hair the one concession she made towards her feminine side, she often dressed up in the boy's uniform for most of her time at school, and only very rarely dressed in the girl's uniform for a few special events or occasions.

If she wasn't so smug and bratty, you wouldn't be so hesitant to admit you found her at least a little cute. Physically, she still kinda was, even if it was mostly drowned out by that elitist attitude she practically clubbed everyone over the head with.

And in a boy's uniform, her figure was...not really all that special. You'd know because as her neighbor, accidents happened quite a few times, and you've gotten an eyeful of her naked body more than once. Likewise, she's seen you naked a few times as well. Sure, it was embarrassing at the time, but at this point you like to think you were mature enough to not dangle the matter over her head.

At least until you needed to shut her up when she tried to do so to you.

That being said, her chest wasn't flat, but it wasn't so great that she had to bind it in order to hide any affect it had on her figure. A boy's uniform jacket did that job well enough unaided. Though if you didn't know she was a girl, you might have been judged a bit differently for taking the occasional peek at her ass, which the pants did not hide nearly as well.

It's odd contemplating the ass of the girl you have a rather frustrating sort-of friendship with, but it helps you drown out most of the bragging you've already heard from her at one point in your life or another. And thankfully, by the time your focus returns to the ceremony she's already finishing up.

“-ecome the Indigo League Champion!”

Apparently other students found her ranting charismatic, because they begin cheering and clapping much like they had done for Professor Oak at this point, who humors his granddaughter by clapping as well, though you imagine he was at least a little irked that she technically stole his show for a moment.

“Thank you for your passionate words, Blue. I hope they've inspired the rest of your classmates to give their all for their own dreams as well.”

With a proud, smug grin on her face, your rival dramatically exits the stage and heads towards her small group of fans, who have probably wrote entire novels dedicated to praising Blue simply for breathing.

“And lastly, we have Green, the exchange student who joined us this year. Their test scores were exceptionally high and they've made quite the impression in their short time with us.”

Oh right, you forgot that a new student enrolled at the start of the year. Circumstances in Johto apparently caused their family to move with other relatives here in Pallet Town. Luckily, Green was apparently smart enough to transfer over to the Academy with no issues.

Now that you think about it, you don't remember if you've ever actually met them before. You're having trouble remembering a face to go with the name.
