Description
Bisca Mulan immigrated to Fiore from the Alvarez Empire, facing poverty upon arrival. To survive and afford medicine for her pet mouse Sunny, she adopted the alias "Mulan Rouge," committing petty crimes while falsely claiming Fairy Tail membership to exploit its reputation. Using her gun skills, she intimidated townspeople and looted local areas, including a dessert shop where she encountered Erza Scarlet.

Erza confronted Bisca over the impersonation. After stealing Erza's underwear and fleeing, Bisca was overpowered; Erza deflected her gunshots and defeated her. Bisca pleaded for mercy, explaining her situation, but Erza stressed guild integrity. Ultimately, Erza offered Bisca legitimate Fairy Tail membership. This pivotal encounter transformed Bisca, shedding her arrogant, vulgar persona for loyalty and kindness. She discarded the Mulan Rouge alias and officially joined the guild.

Within Fairy Tail, Bisca teamed with fellow western immigrant Alzack Connell. Their partnership grew into mutual affection. A snow globe-like lacrima reward from their first mission became a treasured keepsake. They eventually married, with Bisca taking the surname Connell. Following the seven-year Sirius Island time skip, they had a daughter, Asuka Connell. Bisca's appearance evolved: sharper features, a more curvaceous physique, and her long green hair styled into a thick lower braid, retaining her red lipstick and brownish-purple eyes.

Bisca wields Requip: The Gunner magic, summoning firearms from a pocket dimension. Her arsenal includes a Magic Sniper Rifle for Homing Shots and Stinger Shots, a Magic Pump-Action Shotgun for Wide Shots, Magic Double Machine Guns for Bullet Storm barrages, and a Big Bazooka. An expert markswoman, she demonstrated exceptional accuracy during the Miss Fairy Tail Contest by shooting holes through airborne coins. Her skills were trusted for critical missions, such as operating the Jupiter cannon against the Spriggan 12 member Ajeel Ramal during the Alvarez invasion.

Bisca participated in key Fairy Tail conflicts. She aided injured Master Makarov during the Phantom Lord Guild War and fought Phantom Lord's Shades. In the Battle of Fairy Tail arc, she entered the Miss Fairy Tail Contest but was petrified by Evergreen's Stone Eyes as part of Laxus Dreyar's scheme. Post-time skip, she took part in the Grand Magic Games and Tartaros arc. During the Alvarez war, she defended Magnolia before retreating to Crocus with the guild for larger battles.

She resided in Fairy Tail's female dormitory, Fairy Hills, appearing in OVAs like "Welcome to Fairy Hills!!". Determined and fiercely loyal to her guild, she fights for comrades against any odds. While headstrong with guildmates, she displays noticeable shyness and affection around Alzack. Her journey traces a path from desperate immigrant criminal to devoted guild member, wife, and mother.
