It's only natural that those who aren't good enough will…disappear.
Description
A former solo idol who's been the talk of the town. She gained cult-like popularity among the troubled female youths of today, who worship her as their "God". While she intimidates those around her with her rough language and behavior, she has a fragile and vulnerable side to her.
She used to be in a unit with Mikoto Aketa that disbanded for as yet unknown reasons. Prior to their unit debut, Luca and Mikoto were idol trainees together. She thinks Mikoto's decision to join 283 Production is ridiculous. She bears a grudge against Mikoto's unit partner Nichika, who she sees as having taken "everything" from her. Luca is still managed by the same Manager who also managed Mikoto before she moved to 283 Production.
She is the daughter of retired idol Nami Yakumo. Luca is close to her mother and is extremely protective of her, likely due to her childhood experiences of seeing her mother struggle to get away from industry forces and the press as a recently retired idol, which is shown in "Seven#th". The source of her hostility towards 283 Production appears to be because of the circumstances between her mother and current 283 Production President Tsutomu Amai, who was Nami's producer when she was an idol.
In the "December of The Lines" scenario event, Luca encounters Hiori Kazano who is taking a dance training course based at an agency Luca also frequents. Mistaking her for an idol trainee, Luca befriends Hiori, whose hard work and willingness to learn reminded Luca of Mikoto during their trainee days. However, upon learning the truth about Hiori being a 283 Pro idol, Luca abruptly ends the friendship, leaving Hiori quite shaken.
