At Astra Knyght Academy on Philos, Xavier serves as prefect of the Starhunters class while the past-life MC is prefect of the rival Moonchasers class. Both are members of the elite Order of Lightseekers — knights answering only to the royal family. Their competitive training relationship forms the emotional foundation of the Myth 1 'Shooting Stars' story. Xavier is the crown prince and son of the King of Philos; his academic career is shaped by royal duty and the expectation of the Gladius Ceremony to come.
