Things to Consider
Violence
The series prominently features violence as a core plot element, including murder and assassination. The protagonist, Ulises Albet, is implicated in a murder, and the story involves an assassin character who commits killings. There is also a backstory involving domestic violence and suicide.
Ulises Albet becomes the prime suspect in a murder during Mobile World Congress week. A character named Ramisa is a 'professional assassin' who 'committed murders in other European countries earlier' and 'kills Lucas' when he becomes a 'loose end.' Officer Alba, a police officer, works for the antagonist Damian Diskin and 'manipulates the crime scene' and is involved in 'Ramisa's death.' The backstory for Ulises mentions his 'sister's suicide due to bullying.' Damian Diskin's motivation stems from 'his abusive father assaulting his mother on a regular basis,' which led to his mother's death. The 'Day One' device itself is shown to make a test subject 'suddenly turn violent' through emotional manipulation.
