At the beginning of Legend, we are introduced to one of our main characters: Day. He is hiding near his family's home, waiting for the plague patrol to pass by, silently hoping that nothing is wrong. Tess is uncomfortable being inside of a plague sector, and voices her concerns. The Republic's plague patrol marks his family's home with an X with an additional line crossing it, which gives rise to many concerns and a desperation to find cures ignites a fire in Day.
The Republic's Prodigy
With the plague showing its face in his home, Day makes a plan to break into a hospital for the cure. Entering the hospital in disguise, Day proceeds to locate some plague suppressants, but no actual cures. He is then caught, and escapes by jumping out of a window, using one of his two knives to safely descend from the several story fall.
A Personal Tragedy
After successfully escaping the hospital, Day runs into a Republic Officer in the form of June's big brother: Metias. The two of them stare one another down and carry a very short conversation, before Day flings his knife into Metias's shoulder, quickly following up the move by diving into the sewers even in his injured form. Using the twisting, winding path of the sewers, Day escapes the scene completely, and if later found by June.
When we are first introduced to June, we find her on the side of a building, training herself to be able to match the infamous criminal Day. We soon discover that she is actually breaking rules without a care in the world, because she's the Republic's Prodigy, someone who scored a 1500 on their test, granting her access to things no one else would dream of. At one point or another, June enters a car with her brother Metias and is very lightly scolded by him, before he shows how proud of her he is which highlights their close relationship. Metias then tells June that he is going to go on an assignment, to which she says he should bring her along. He never agrees to it.
After the encounter with Day, Metias is found dead, one of Day's knives piercing his heart. This leads to June being forced to investigate the crime scene of her brothers death, her own nightmares come to life. After the investigation, there is a funeral ball held for the young officer, where June meets Chian, a man who was previously Metias's mentor. June is graduated early from her university and put under Captian Jameson as a replacement for Metias. She is instructed to hunt down Day.
After being ordered to hunt down Day, the clever prodigy tried to lure him out with the promise of plague cures. Day and June encounter one another for the first time, and Day picks up on various mistakes she makes when confronting him while disguised in an alleyway. He leaves the scene, and June decides then to go undercover in the Lake Sectors. She comes across a skiz fight that Day and Tess were attending (though she didn't know that), and watches as Tess is thrown into the ring with Kaede, a very powerful skiz fighter. June steps into the conflict and fights Kaede, shattering her arm. Day then sets off a smoke bomb and recovers both Tess and June, dragging them to safety.
