Yana is a ritual dancer on Jiffon Island, performing alongside her partner Aoyu as the duo Vaikedaam. Maintaining virginity is required to preserve their ceremonial roles. She has long brown hair and purple eyes, dressed in traditional attire: a light-colored kimono, black stockings, and sandals.

She and Aoyu respond respectfully to visitors assisting the island community or formally hired by it, yet show apathy toward others unrelated to their duties. During preparations for an orc invasion, she and Aoyu attempted to motivate Yusuke Yotsuya by performing an idol-style song while he worked, though he remained unimpressed.

Her involvement centers on the island's cultural traditions and conflicts. The celibacy requirement stems less from personal dedication and more from prolonged isolation caused by orc threats limiting social opportunities.
