June Iparis, the Republic's fifteen year old prodigy who scored a perfect 1500 on her Trial, the Republic's mandatory test system. Born into an elite family, her parents were mysteriously killed in a car crash, leaving Metias, her older brother, to care for her. When Metias is murdered and Day is the prime suspect, June sets out to find him but ends up slowly falling in love with Day. Her first encounter with Day was a ruse to find out his true identity, only seeking revenge for her brother's death. She's very analytical and smart, able to keenly survive on the streets, and a bit of an uptight person. She has long, dark brown hair usually tied back in a high ponytail. She has dark brown eyes with golden flecks in them. • '''Daniel 'Day' Altan Wing''', the sixteen year old legend born in the slums of the Republic.

He also has a limp in his left leg and an "imperfection" (a lighter patch of blue) in one eye from when the Republic experimented on him. Day is described as being extremely agile, even more so than June. He, like June, is confident and stubborn. He also scored a perfect 1500 during his Trial, but was lied to from the Republic, being told he scored 674 (45%). In
