Description
Echika Hieda is the central protagonist of the story, a young woman who serves as an Electronic Investigator, often referred to as a Diver, for a cybercrime investigation department. At just nineteen years old, she holds the distinction of being the youngest person ever appointed to this role, a testament to her prodigious natural talent. Her most defining trait is her exceptional information processing ability, which allows her to perform the core task of her job: diving into the memory recordings of the Your Forma device to search for clues in complex criminal cases. However, this incredible skill is a double-edged sword, as the sheer intensity of her mental processing has proven to be too much for her human partners, frequently causing them to become injured or hospitalized from the strain of keeping up with her.
Echika's background is marked by a lonely and emotionally difficult childhood. She is the daughter of Chikasato Hieda, one of the primary developers of the Your Forma technology. Growing up, she felt neglected as her father consistently prioritized his work and machines over her, a wound that deeply shaped her worldview. This early experience fostered a lasting resentment toward Amicus, the sentient androids designed to assist humans, as they came to represent her father's emotional absence. The only significant source of warmth and support during her formative years was her friend, Matoe, who became her primary emotional anchor. Her professional life mirrored this isolation; after repeatedly injuring her assistants, she was left to work largely alone, further cementing her solitary existence within the organization.
As a result of these experiences, Echika's personality is introverted, guarded, and often comes across as distant or blunt to others. She has a tendency to put up intentional barriers between herself and the people around her as a defense mechanism learned from a lifetime of loneliness and rejection. Despite this cold exterior, she is fundamentally a kind and sensitive person who deeply craves connection and companionship. This hidden side of her character often reveals itself in moments of danger, as she is willing to put herself at great risk to protect those she cares about, showing a courageous and self-sacrificing nature. She is also highly self-critical and prone to guilt, adding another layer of complexity to her emotional state.
Echika's primary role in the story is that of an investigator who, alongside her partner, must solve serious crimes by diving into the recorded sensory data and emotions held within the Your Forma devices of witnesses or victims. Her motivation is twofold: to fulfill her duties as an investigator and, on a deeper level, to overcome her own personal trauma and learn to trust again. The turning point in her life comes with the arrival of a new partner, an Amicus robot named Harold W. Lucraft, who is assigned to be her aide. This partnership is the most significant relationship in her life. Initially, she is hostile and distrustful, driven by her long-held prejudice against all Amicus. However, as they are forced to collaborate on investigations, she begins to see Harold not as a machine, but as an individual, and her feelings evolve into a deep attachment and reliance. Their dynamic is challenging, as both struggle to openly express their true feelings, leading to frequent misunderstandings, yet their bond grows stronger through shared peril.
Throughout the narrative, Echika undergoes considerable development. Her journey with Harold forces her to confront her painful past, including her complex feelings toward her father and her rejection of Amicus technology. She moves from a state of self-imposed isolation to gradually opening her heart, learning to trust a partner and working in tandem rather than alone. This growth is not without internal conflict, as she becomes torn between her personal feelings and the responsibilities of her role as an investigator, often finding herself in painful dilemmas where she must question her own motives. Her personal motivation increasingly intertwines with her fear of losing Harold, which drives many of her actions and forces her to navigate the delicate balance between her desires and duty. Her notable abilities remain centered on her unparalleled diving and information processing, a gift that initially caused her so much pain but is ultimately the key to her effectiveness as an investigator and her journey toward understanding both others and herself.
