Genius Society #4, known as the Lord of Silence, information on Polka Kakamond is as mysterious as her appearance. She has had her portraits and sculptures destroyed across the universe, and is suspected of being involved in the deaths of many Society members, including Genius Society #27, Emperor Rubert.

Herta is very interested in the Lord of Silence. Although there has been no news from Polka Kakamond for many years, Herta believes that she is still alive. She is elusive, and there is scarce information of her left in the universe. On the other hand, there are many rumors about her: Apparently she was the only one to vote against Elias Salas and probably having something to do with Nihility's Device IX.

If a woman removes her white coat and puts on a flashy candy-colored evening dress and appears in the cosmos with a dagger in hand, witnesses must call for help: The Lord of Silence is likely to target anyone.
