Masahiko shrugged. Chia thought the street made him uncomfortable. Maybe just being outside. He'd traded his gray sweats for equally baggy black cotton pants, cinched at the ankle with elastic-sided black nylon gaiters above black leather workshoes. He still wore his black tunic, but with the addition of a short-billed black leather cap that she thought might have once been part of a school uniform. If the tunic was too big for him, the cap was too small. He wore it perched forward at an angle, the bill riding low. "I live in Walled City," he said.
