Rikka Sumeragi

Rikka Sumeragi is the last descendant of the prestigious Sumeragi ninja clan, living in the futuristic, corporate-controlled metropolis of Brad City. Her life of rigorous training and peaceful family bonding was shattered when a ruthless mercenary group attacked her home, assassinating her father, Harold—a brilliant scientist who merged advanced robotics with the clan's traditional ninjutsu—and stealing his life's work. Vowing to uncover the truth and reclaim her father's technology, Rikka adopted the secret vigilante identity of "Black Fox." By day, Rikka is an athletic, kind-hearted teenager trying to live a normal life. By night, she slips into the neon-drenched shadows of Brad City as a highly lethal, agile force of justice. Her arsenal is a unique fusion of ancient martial arts, stealth, and futuristic gadgets, most notably her father's three animal-shaped AI drones: Oboro (a tactically minded mechanical dog), Madara (a nimble flying squirrel drone), and Kasumi (a sharp-eyed eagle drone). Together, they operate from her hidden hideout, monitoring corporate crimes and hunting down the Lauren Group, the mega-corporation responsible for her father's death. Physically, Rikka has long, dark blue-black hair usually tied in a high ponytail, expressive blue eyes, and a lithe, athletic frame. Her Black Fox suit is a masterpiece of stealth technology, offering light armor, optical camouflage, and grappling hooks. In combat, she utilizes a specialized katana, smoke bombs, and her drones to overwhelm opponents. Though fueled by a desire for justice and revenge, Rikka strictly adheres to her grandfather's teachings of the Sumeragi ninja code: to protect the innocent and never lose her humanity to hatred. She is empathetic, protective of her friends (like Lily, a girl with psychic abilities she rescued), and possesses a fierce, unyielding spirit.
