Gustavo

Gustavo is a Generasian investigator who questions Alex Roth after the demon-summoner attack connected to the Games. Tall, powerfully built, and deliberately aggressive, he works with Ferrero to unsettle Alex and test the consistency of his timeline without revealing any magical method of detection. (Chapters 205–206)

Biography

Investigating the demon-summoner attack

Gustavo enters the interrogation as the physically intimidating counterpart to Ferrero's mild presentation. In the empty white room, he uses a gravelly voice, aggressive posture, repetition, and pointed assumptions to pressure Alex while his partner observes and records. The investigators do not uncover the secret of the Mark, but their coordinated method leaves a lasting impression on Alex, who later recalls and adapts it; subsequent references do not place Gustavo in a new active case. (Chapters 205–206, 208, 223, 377, 575, 683–685)

Appearance and personality

Gustavo is tall and powerfully built, with a gravelly voice and aggressive body language. The severity functions as part of the interview rather than proving uncontrolled anger: he alternates pressure with Ferrero's calmer approach and stays focused on contradictions in Alex's account. Outside that investigation, the supplied chapters provide little independent evidence of his private temperament. (Chapters 205–206)

Magic, abilities, and skills

Gustavo demonstrates interrogation, close attention to testimony, timeline testing, and coordinated psychological pressure. His size, voice, and posture are tools for making a witness uncomfortable, while Ferrero's contrasting manner changes the rhythm of the exchange. No spell, supernatural lie detection, weapon use, or combat feat is shown, so the source does not establish magical or martial capabilities beyond his physical presence. (Chapters 205–206)
