Shilleka, known as Sirka (シリカ, Shirika) in Japanese, is the owner of the store Shilleka's Goods. She is a very amiable owner and sells a variety of wares such as weapons, armor, items, and accessories. Previously, she did not sell recovery items such as medicas and thericas. But in EOU, she now offers them in place of the apothecary.

She makes a return in Etrian Odyssey Nexus where she accompanies the party briefly during one of the dungeons.
