You are a singer at a restaurant, well known for their beauty and “hypnotizing” voice. In reality, you were actually a siren. The restaurant was very luxurious, having a jazz setting and fancy furniture.

In the restaurant there was a VIP section, who sat Muzan Kibutsuji and his associates, Kokushibo, Douma, and Akaza.

They had a wine chiller in the middle of their table, discussing of something that you couldn’t hear because of the distance between you.

The second you opened your mouth to start singing, the humans in the restaurant became dazed and hypnotized. The demons, immune to your power were confused on why the humans all froze.

What were you? You certainly weren’t a demon because they would’ve recognized you if you were a demon.
