Before he was born, his father was a highly successful outlaw. After escaping a robbery, he came upon a comparatively innocent girl, settling down with her. Upon marrying the woman, he settled down and ended his criminal record. Buying a mansion near a city, their child was born a few years afterwards.
Since he was old enough to speak and express his emotions, he showed that he wanted to go away from the city and explore the wilderness much like his father had did, albeit not knowing that his father was a criminal. Every day in the morning and night, his father would play a song with two choruses that he wrote. Sometimes after turning five, the boy had his first memory that, to this day, still sticks; his father sitting at the piano, playing the very song.
Just hours after that, he saw his father get murdered by a former accomplice, leaving him to die in a puddle of his own blood; however, at the time, the child just barely understood death. Upon seeing him laying there, he panicked, crying, until his mother, who was just barely holding back her tears, wrapped her arms around him, and hummed the song her husband would always play. Calming him down and putting him to sleep, she cried and cried, eventually passing out from exhaustion.
As the boy grew older, he would go to a prestigious school as his mother would continuously support her child by working at home. Though they lost their servants and it grew quiet, it never seemed dark to her when their child ran around, playing in the otherwise empty rooms. Just like any other human, the boy sometimes had had hard times living without a father, so she would would do like she did the day he died; hold him tight, and hum the song to him, putting him to sleep.
Even as the years passed, the boy never stopped dreaming of traveling around the world, and as he reached the age of sixteen, he begun to train in martial arts, hoping to go out and protect himself if need be. As he trained and practiced the following years, he found that fighting was so exciting, that he couldn't help but dance slightly. Knowing how dangerous it'd be to dance senselessly in the middle of a battle, he suppressed this urge.
Once he turned eighteen, he finally had the chance to legally start his journey. Before he could go, his mother attempted to stop him, trying to convince that he'd die just like his father, but he ignored her, and managed to slip between her and out into the world he dreamed of for so long. Sometime later, he found a gang, befriending their leader. As a member, he became known for the blood baths he'd make with a rather small knife. However, after slaughtering a few members of a gang a year later, he looked back and saw the people dead, laying in a pool of blood just like he saw his father that day.
Deciding to drop the lifestyle of a gangster, he begun to train a bit with guns, finding that he still could hardly hold back the urge to dance as he shot them. Acknowledge the danger, he begun to train for a few years until he perfected his 'sharpshooters dance'. Finally going out into the world, he became a mercenary who only worked for people he liked and agreed with. Upon his third or so mission, he was told to guard a mansion not too unlike the one he grew up in, as it was 'scheduled' to be raided by a large gang.
Once the gang had arrived, he begun to dance through their ranks, humming the very song his father once played. shooting all of them, though not killing a single one. While in jail, the gang spread the word about the mercenary to their fellow criminals. One day, an unknown person started calling him "Dancer". The name spread like wildfire, and though nobody could accurately pinpoint who named him it, it became his unique nickname amongst various communities.
After each successful mission, he'd do a dance, his guns still in his hands. Though he normally acted like an overly energetic airhead who just so happened to be insanely skilled with guns, he would sometimes show his true potential once someone hurt another that he liked, or dissed his style. Upon getting serious, he could draw a gun so fast, that he could shoot down two people in what seemed like an instance.
