But in 2005 St. Francis began accepting boys.
And like any other boy, they wanted to play football.
Now thanks to a principal who is an avid football fan, times are changing up in Manoa.
St. Francis's principal, sister Joan of Arc Souza, believes you have to think outside the box.
And this sister is practicing what she preaches.
"I'm behind all athletics. If a student is involved in athletics, it diminishes the opportunity to be involved in drugs and other things, so if the students want to play a sport, the school will sponsor it," said Sister Souza.
This year some students wanted to play football.
So for the first time in the school's history, Sister Souza authorized it, and six students played on the intermediate boys Pac-Five team.
"It's pretty cool, because we're making history for St. Francis," said Wolfpack quarterback Austin Ursua.
The boys immediately made a difference.
On Saturday they finished the year out with a win, giving them a 4-2 record, good enough for 2nd place.
Next year they're looking for more.
"My goal for next year is to go to the championship, just go all the way, no losses," said Wolf pack running back Isaac Savaiinaea.
To Sister Souza, wins and losses don't matter.
She tells her students only one thing does.
"It's how you play the game, and watching them it's been excellent."
She's not the only one looking at her boys with fondness. So are many of their teammates, and even some of their opponents.
"They think we're lucky because it used to be an all girl school, and they say next year I like transfer there."
The girl to guy ratio at St. Francis is 10 to 1, which is why the other teams are jealous.
Aside from football, the boys are all doing extremely well in school.
Sister Souza says all six of them are honor roll students.
