Every week, she traveled by train to visit her aunt and noticed a boy who also frequented the route.

Their brief encounter set in motion a series of unforeseen events that led them to a shadowy group with inexplicable control over everything, though its existence went unverified. The story took a dramatic turn when the boy suddenly vanished, and they found themselves transported to an alternate universe.
