Nicole has pointy ears, a bit like elf ears, but not as long as Alice's.

Nicole is wearing a white, off-the-shoulder dress. The hem and sleeves are decorated with a blue-to-light blue gradient. The collar features a layered design of white and dark blue, embellished with an orange gemstone and a blue fabric wing-shaped pattern.

White wing earrings with gold accents, a white corset-like belt, iridescent translucent white tights with lace garters and yellow-orange gemstone tassels, and white and light blue heels with gold-brass accents and white frills.

Despite being physically unable to speak out loud, Nicole is very talkative. She often spontaneously broadcasts her thoughts directly into the minds of others, often confusing them. Alice warned the Traveler, "Watch your thoughts," when he first encountered her.
Nicole literally lives in Teyvat's past and loves to vividly recount bygone eras. Her stories often begin with the words "long ago," and she delights in immersing others in the atmosphere of bygone days.
