"I like you. You remind me of my sister in Kiev."
—Luka Volk to Selina Kyle[src]

An unnamed girl was a sibling to the notorious Whisper Gang smugglers Luka Volk and Jacob Volk. She lived in Kiev, Ukraine.[1]


Unlike her brothers and their loyal gangsters, who stayed in Gotham City, United States to seek revenge on the Court of Owls, Luka's sister remained to live in their family's home city of Kiev, Ukraine.[1]


Luka Volk compared Selina Kyle to his sister in terms of personality when Selina cynically quipped about the "stupid masks" worn by Whisper Gang members.[1]
