girl was found amidst the burning fields of Ikaruga where she was rescued, and
then adopted by the family of Vermillion. It was because of her outstanding
combat activity that she became a high-ranking member of the NOL using the Nox
Nyctores "Arcus Diabolus Bolverk" revolver. She was made Jin
Kisaragi's subordinate by the NOL, although Jin treated her poorly due to
her sharing the face of his Saya. When Jin rushed off to hunt down Ragna without
permission from the NOL, Noel was assigned to stop him and bring him back to his
post at the Library.
In truth, Noel suffers from amnesia. She is actually u-12, the predecessor of ν-13.
Both are replicas of Saya, sharing her face, voice, and memories, though no
answer is ever given to how they came to this end. It isn't far fetched to think
the creators of both needed the original to accurately copy those traits from.
She was being immersed in the Boundary in the opening of story mode, though
after the attack that destroyed Ikaruga she remains the sole survivor in that
area. She eventually becomes the "eye", the true possessor of the
Azure Grimoire. She is easily won over by small, cute animals (agreeing to be
dressed up by Litchi if she could play with the Panda
in one story path, and even shouts "Hands off the panda!" during
battle with her) and has an inferiority complex with her bosom.
