Talk to the Blonde.

You turn to face the cute woman holding the book.

The fiery girl with the knives was definitely interesting, but it was impossible to ignore this incredibly buxom priest-girl.

Not wanting to stare, you decide to talk to her.

"So how's the book?" You flash her a charming smile and she blushes once again.

"Silly, it's not for recreational reading! This book is my healer's tome! It's basically a textbook for my magic, helps me remember my spell verses and movements and stuff."

This girl is almost unbearably adorable.

"Verses and movements?"

"Yeah, learning healing spells is kinda like learning poetry, you have to be able to recite specific lines and verses, and the book helps me remember!"

"What about the movements, is there a dance component?"

She giggles at you and shakes her head.

"No! You know my magic is uh... Well at it's source it's very sexual, I have to remember a lot of very subtle movements and tricks for it to work best."

"Huh, that sounds really difficult, I'm impressed."

The lovely lady's cheeks are flushed a warm rouge at your flattery.

"How about an example, what kind of spells do you know?"

"Well, my specialty is healing, so I can repair any wounds you guys take in battle. Although I also know a few buffs, to make you stronger! Talk to me before you go into a fight and I'll give you some cool magic upgrades! Remember though, they only last for a bit, so we usually have to recast them each time we fight."

"You know, you sound pretty amazing, what's your name?"

"Hm? Did I forget to introduce myself?! Oh my, uh... I'm so embarrassed. My name is silly and long, so you can call me Fia!"

"What a cute name."

Another of her heart-melting blush/smile combos ends your pleasant introduction.
