Background
Due to her intelligence, Billie developed an attack method slightly different from other Corrupted’s. She rewrote the defeat condition of every game in her database to "death". Under Madam Monzano's order and Lilith's influence, she developed dozens of games inciting players to kill one another. Most of her games don’t allow survivors. Lilith doesn't appreciate this. After the prosperous Las Prados became hollow, Billie still wanders the buildings, turning abandoned sites into "playgrounds". When enough intruders are detected, she secretly commences her games.
Billie is equipped with a multi-lingual system. She has a certain level of intelligence, she can think like an eight-year-old child and is capable of dramatic expressions. Corrupted by the Punishing Virus, she started to enjoy provoking her service recipients with a childlike tone. Later, after she reunited with Lilith in Las Prados and is "upgraded", she now stays as a smiling clown in her regular mode with a different behavioral model.

The design paper of BIII-777 already existed in the Golden Age. Through several iterations, its prototype has evolved from a gaming device with the same height as an adult human into a mini CUB equipped with service and entertainment features. Now it can show simple expressions in the game mode as a 'dealer' or guide tourists as an "attendant".
Billie's database holds the rules of both ancient and modern games, making her a 'walking museum' of games. "I can always recommend games that suit the current vibes the best and provide all kinds of props. O-Of course, I promise all games are exciting!" —Billie's Self-Introduction.
Billie was deployed as a guide CUB in Las Prados after the completion of its development. However, the Punishing Virus broke out not long after that, and Madam Monzano ordered a forced shutdown of Billie before the CUB got corrupted. After that, Billie was woken up again as a CUB. Years later, she is still executing orders that never existed and carrying out the "screening" in the deserted Las Prados to her understanding. And the props she was previously equipped with have now become dangerous weapons.
