Paruko Nanana shines as a sixth-grade student at Aibo Academy and the star reporter for its Broadcast Club. Her live Buddyfight commentary, often delivered while soaring on her Martian UFO buddy Takosuke, is renowned. Initially skeptical of Gao Mikado's skills, she dismisses his wins against rivals like Rouga and Tasuku as mere luck, dubbing him "king of the newbies" and "king of dumb luck." Her broadcasts openly display her favoritism. She fights using a Hero World deck built around the Superhero attribute, leveraging Takosuke and her sharp observational skills honed from watching countless duels. This expertise allows her to analyze opponents' strategies and deploy Takosuke's "Martian Zap-Zap Beam" for precise damage. Strategic cards like "...Or So the Dream I had Went" counter enemy spells, while "Ride" bolsters Takosuke's defense with protective Items, blocking direct assaults. Her transformation call rings out: "All the way from Andromeda I shine. Luminize! Falling Twinkle Star!" A Season 2 possession shifts her to a Katana World deck focused on the Skull Warrior attribute, with Kalavinka, Uguisukomachi as her buddy. This deck incorporates Jin Magatsu's tactics, including the set spell "Return to the Underworld." Her transformation call changes to: "Ravenous fiends walking a wicked path, witness their awesome power! Luminize! Hundred Ancient Katana Warriors!" This possessed state ends after Gao defeats her. Key story moments include witnessing Kiri Hyoryu's apparent kidnapping by Rouga Aragami in episode 24; she alerts Gao's group and commands Takosuke to chase the abductors. Later, in episode 53, she doubts Zanya's assertion regarding the Purgatory Knight's identity as Tasuku Ryuenji until Noboru reveals his face. She competes on Team Goddess in the Gaen Cup, facing Gao in episode 49 where her deep knowledge of his deck poses a significant challenge. Twenty-three years later, during *Future Card Buddyfight Ace*, she has married Gao Mikado, taking the surname Mikado. They have two sons, Yuga Mikado and Haru Mikado. Her appearance evolves: in earlier seasons (1-5), she sports hot pink hair, bright teal eyes, a yellow-and-white T-shirt, a blue tie with a lightning bolt, red shorts, black leggings, a gray belt, a watch, sweatband, yellow socks, and red-and-pink sneakers. By Season 6, her attire changes to a white top, pastel pink skirt, and hot pink sandals. Her broadcasting career extends beyond school; in *Future Card Buddyfight Hundred*, she works professionally for a news agency covering Buddyfights.
