She appears in Episode 8 and is one of the eight contestants who are picked to perform in Mars' Brightest.
In the first round, she had to face the Mermaid Sisters. As GGK came on the stage, the host asked her what she will sing for them, but GGK said she isn't going to sing, but she is forced to sing as she connects to the universe, as she was dead, but then returning to life again. She also said she was 13,800,000,022 years old, since she was connected to the universe. As no one understood her, they let her sing her song "Milky Way". After the Mermaid Sisters performed their song, Catherine quickly announced that GGK was the winner, even though she didn't had winning qualities, it was just that the Mermaid Sisters had reasons to lose.
In the second round, she was asked by Catherine what led her to her current style of music, she stated that she grew up in a village at a desert and that it was no place for a nonsensical person like her and thus, her soul died there. She was stated that if there is no place for her, she just needs to make one for herself. Thus, she went to Alba City and found herself.
After facing off against Angela Carpenter in the second round by singing "Gravity Bounce", Catherine states that it was a very close match and considers both singers very talented. However, she criticizes GGK for not mixing up her routine and therefore chooses Angela as the winner. Despite this, GGK congratulates and hugs Angela before leaving with Benito commenting that in the other years of the show, she would have been on the finals, making her last appearance in Episode 11.
