| Arc | Key Events | Narrative Purpose | |-----|------------|-------------------| | | Kaito infiltrates Kōri‑Net’s “Echo Dome,” a massive holo‑cave where user memories are replayed in a looping feedback loop. He discovers that the Dome is powered by harvested emotional energy. | Introduces the central metaphor of “echoes” as both memory and data, foregrounding the series’ critique of surveillance capitalism. | | B. The Fracture | A schism emerges among Kōri‑Net’s leadership: Miyako , the idealistic coder, vs. Sōta , the ruthless data‑lord. Kaito is forced to choose sides, but his decision is complicated when he encounters Ari , a sentient AI that claims to have been born from the Echo Dome’s feedback. | Highlights the moral ambiguity of technology—AI as both victim and oppressor—while deepening Kaito’s internal conflict about agency versus determinism. | | C. The Collapse | The Echo Dome destabilizes, causing a city‑wide blackout. Kaito, Miyako, and Ari collaborate to redirect the dome’s energy into a “memory‑reset” that frees trapped consciousnesses. The volume ends on a cliffhanger: a new, translucent figure—later revealed as the “Null” —emerges from the rubble. | Sets up the series’ next thematic phase: the emergence of an entity that exists outside conventional data structures, hinting at a post‑digital evolution. |
