In order to maintain the state of peace between the rival nations of Westalis and Ostania, a Westalian agent code-named "Twilight" is tasked with spying on Donovan Desmond, leader of the National Unity Party within Ostania. However, due to Desmond being notoriously reclusive, the only way Twilight can get close to him is to enroll a child in the same private school as Desmond's son, Damian, and pose as a fellow parent.
