Billlie

* South Korea
* Japan

**Billlie** (Hangul: 빌리; Katakana: ビリー) is a South Korean-Japanese girl group under MYSTIC Story. They debuted on November 10, 2021 with their first mini album *The Billage of Perception : Chapter One*.

## Name Meaning

Billlie is a simplified spelling of "Bi11lie". The core element to Billlie's lore is that on the eleventh day, when eleven chimes sounded, purple rain fell from the sky, a girl named Billlie was taken, and the members lie about ever knowing Billlie. "Bi" (비) in Korean means rain, in reference to the purple rain; "11" pertains to the eleventh day and eleven chimes; and the girls "lie" to the world about Billlie.

Apart from the lore, the "B" in Billlie is meant to represent a persons "B-side", the hidden inner self. The name Billlie also combines the name Billie with an extra L, to show how Billlie "hope to connect and empathize with people by showing them their inner self, with a twist in order to create something special".
