Silver Salt (S01E09)

Title: Silver Salt Plot: The KANAE system was an AI created by Kanae, mother to Koki and Asumi. Previously, this same technology was integrated into a vehicle that crashed, leaving 0th and Tsuzuragawa injured. Now, 0th grapples with the lingering effects of that accident, including a struggle with dyslexia due to the AI's poor decision-making. As Kanae searches for a remedy, she learns of a critical flaw in her creation. When she discovers 0th has taken to graffiti as an outlet, she abandons her work. Following Kanae's untimely death, the trajectory of the 24th Ward takes a dramatic turn.
