Being raised in a family of all boys, while Flikki was the lone girl, very quickly Flikki had to learn how to hold her own among the others in her family. Her Father, "Flicko Sicko", put bread on the table in the form of being a contract killer, and while he did what he could to hide his career from his children, it ultimately wouldn't remain a secret for long, as each of the children would soon figure out what it was their father did when he left home. After this revelation, undeterred by the fact that their father killed people for a living, each of Flikki's older brothers all begged their father to allow them to shoot his gun, a small, but accurate, compact sniper rifle.

Each child would take their turn firing the gun towards wooden targets outside their home, and each child to do so would miss their shots entirely. When the young Flikki tugged at her Father's shirt asking for a turn, neither he nor her brothers thought she would be able to do anything with it. Her smaller size and stature seemingly being too much to wield the rifle properly. However, after a very brief moment of taking aim and holding her breath, Flikki fired the rifle, and the bullet travelled straight to the center of the target she was aiming for. Stunning her father and brothers, she then climbed up on her Father's shoulders, and jumped. Flikki spun around incredibly fast, and as she fell towards the ground, she fired off three different shots all before touching the grass below. Each one hit their mark perfectly.

From that moment forward, Flikki knew what her calling was, and she knew then and there, that very rifle would be hers one day. Once all the excitement died down and the family returned inside, each of her brothers begged her to teach them how to shoot like that. But Flikki could only smile mischievously as for the first time in her life, she was the one with all the power. She noticed from then on that her brothers started treating her far more nicely, and some even went out of their way to try and do things for her. All in the hope that she would teach them what she knows. But each time she was asked, she would simply tell them that they need to shoot better.

Despite the tough exterior she developed from being the only daughter amongst a sea of sons, Flikki has always had a softer side to her that she doesn't let many people know about. She is most often seen in a very serious, oftentimes bitter mood, and will be quick to lash out at those that irritate her. These are all behaviors she grew to be accustomed to from her years of dealing with the shenanigans of her siblings. Always feeling like she is trying to prove that just because she is a woman, doesn't mean she isn't as tough as any man. Especially with her rifle in her hands. Naturally, given her talent with it, her father, once he retired, decided to allow his youngest child and only daughter, Flikki, to carry on the heirloom rifle. Much to the disappointment of her brothers. The rifle, old as it is, is marked up on all sides from tally marks added to it for every life the rifle ended. Staring at it now, Flikki thought to herself how intense it is to hold something in her hands that was responsible for the deaths of so many individuals she never knew.

Because of this, eventually Flikki decided that despite keeping the rifle, she would never end the life of another ever again if she could help it. As luck would have it, around that same time, The Arena was looking for its first batch of combatants, and when she heard she could use her rifle while not ending anyone's life, she saw no better opportunity to utilize her skills.

Not long into joining the roster, Flikki would become acquainted with a man named Gunther, who she saw holding a rather large minigun. She became intrigued by this man, and decided to watch him as he did battle in the arena. To say the least, she was disappointed by what she saw. Seeing someone with the potential to be as deadly as her, yet squandering it all by missing most of his shots. This displeased Flikki greatly, and despite her own reservations, she decided to try and help Gunther improve his aim, not only through a series of lessons, but by teaming up in the Season 3 Grand Ball Cup Tournament.

Despite Gunther's more gentle demeanor, even while holding his rather dangerous looking minigun, Flikki's abrasiveness seemingly was not doing much to help Gunther improve his aim, and more often than not she found herself simply being left frustrated by his skills with his gun. Eventually however, the pair would team up with shield user Otis, for the Boss Gauntlet. Forming the team, Target Practice. During their time in the Gauntlet, Flikki, Gunther and Otis would meet Gunther's grandfather, MISHA. Despite her rough treatment of Gunther, MISHA would go on to talk with Flikki about how much he has heard about her from his grandson, and that he appreciates everything she has done to help him improve. To show his thanks further, he took a look at her rifle and asked if she'd be okay if he made an upgrade to it.

Hesitant at first, she felt an odd trust towards this old man she only just met, and handed her rifle over. After a few minutes of tinkering, MISHA would produce the rifle once more, handing it to her. What she found was a rifle now capable of firing in two to three round bursts depending on the situation, and on top of that the rifle looked brand new. MISHA would tell her he saw all the various scratch marks upon the gun itself, and that he buffed them out for her. At first, Flikki didn't know what to think of this. After all those years, each of those marks that represented a life taken by that rifle, were now gone. Yet rather than get angry, Flikki felt an immense sense of relief. Now knowing she was unburdened by the rifle's violent past and that she could carve a new path with it, free from the shackles of guilt left behind by her Father's past.

After thanking MISHA for his help, Flikki found herself feeling slightly happier than she did before, feeling free to express herself and be just a little less serious as she used to be. As time went on she found herself enjoying the company of both Gunther and Otis as they travel down the Gauntlet.
