Flora Perfume, a pink-haired Mazoku with golden eyes and a sleek black tail, serves Barone with unwavering loyalty despite her endearing clumsiness. Her signature attire—a long black top over white pants and gloves—shifts dramatically in battle, morphing into spiked red-and-blue armor while her hair flares with heightened intensity. Unbeknownst to her, she carries the legacy of Kajitsu Momose, a legendary green card battler wielding Mother Core’s light, reflected in her green-and-white deck and shared spirits like The DoomKnightLord Ragna-Rock and The Providence Hououga.

Driven by devotion, Flora confronts Dan Bashin with a fabricated bomb threat, aiming to avenge Barone’s setbacks. Though defeated, the loss fuels her insight into Barone’s ambitions, prompting her to orchestrate a duel reigniting his resolve. When Barone departs, she aligns with Zolder—Yuuki Momose’s reincarnation and her past-life brother-lover—forging a bond marked by sparring matches, shared deck tactics, and playful "Brother" quips. During clashes over Zodiac X-Rares, she opts for neutrality, siding with human morality over faction allegiance.

The epilogue finds her clad in Kajitsu’s garments beside Zolder, her recovered memories left ambiguous. Her enduring green-and-white deck echoes Kajitsu’s legacy, while her consistent defeats against Dan, Barone, and Zolder underscore her role not as a victor, but as a spark igniting others’ evolution.
