Echo.

Echo reads the city like a moving map. They remember which lifts still run after midnight, which platforms catch the first cyan glow, and which detours are worth the extra climb. Their favorite ride starts without a destination and ends somewhere the crew has never been.

Nonbinary, with a wardrobe that refuses neat divisions, Echo wears oversized white panels, black layers and tiny silver details. They are the person who saves you a seat, checks that everybody made the turn, and quietly hands over the spare charger before you need to ask.
