Yokohama Station SF, Vol. 2 (manga)

Hiroto's journey through the depths of Yokohama Station has led him to Keiha Nijo, leader of the once-great Dodger Alliance, whose technology allows her to obscure her location and evade the station's robotic guards. The Winter War, tactical AIs, and dormant machine minds… Will her whispered stories at l ast reveal the secrets of the station? Meanwhile, engineer Toshiru Kubo steals a gun and deserts JR Fukuoka, where artillery shells explode against the growing concrete in a desperate battle versus the station. What will he find in nearly abandoned Shikoku? Nothing less than anarchy on an island conceded to the inexorable station that will soon consume it, and rumors of a ghost at the power station…
