New Girl-ZexionOC beta thing

Upon walking into the library in the Castle That Never Was, the girl skimmed through the titles of various books on various subjects, staring in awe at the vast collection of literature. Being new to the Organization, she walked about the isles - a strange but, familiar feeling coming over her. Just then she saw another person, he, who's gray-blue hair grew over his right eye didn't notice her as he continued to read the large book in his hands. And just then a gasp escaped her lips and the man looked up, startled.
"Who are you?" he questioned, but then remembered there being a new member, "Nevermind, you must be the new member. We haven't officially met. I'm Zexion."
Wait why am I talking to her like casually like that? I don't even know her.
The girl stared, but at that precise moment after hearing Zexion's name her bright green eyes, lively as they are, dulled to a dark army-green- pupils fading away as if she were in a trance.
"Zexion," she spoke the name mechanically, her voice seemingly a little darker,
"" I shall make you see..."
During which she said this she held her left hand up and a barrier-like wall formed between her and Zexion, shimmering and translucent, yet solid-looking.
"...That your hopes are nothing. Nothing but a mere illusion!" she shouted, her voice replaying the exact words he once said.
" It is he who is Number VI,
who brandishes the Lexicon,
who has the ability to create Illusions."
Zexion could only stare in shock as she relayed information about him.
"It is he who's real name is.."
Zexion's eyes widened his breathing quickened as he stared at the barrier. A boy's image converging on the glimmering surface. A boy that looked a lot like him.
"Ienzo"
Just after the last sound lefter her lips, the girls pupil's started appearing among the misty depths of her dark, olive-green eyes and the barrier-like wall shattered and the girl fell to the floor, unconscious. Leaving Zexion staring at the spot that once held the image of the child- the one who looked like him. The child named Ienzo.
During the time this took place a man with silver hair and orange-ish yellow eyes calmly strode in.
"There you are." He muttered under his breath just as a crash erupted from one of the tall isles.
