Naru Akabane, known as Naru Akaba in Japan, is the younger sister of Aiger Akabane. She plays a key role in creating her brother's Turbo Beyblade, Z Achilles, by taking reference photos for its layer image and educating him about Beyblade types such as Attack, Defense, Stamina, and Balance. She also referees Aiger's first match against Valt.
Naru possesses a highly supportive and inclusive personality, consistently seeking involvement in surrounding activities. Despite her young age, estimated at 7-8 years old, she demonstrates notable responsibility and independence. This is evident when she resides alone in a Beigoma Academy room while Aiger sleeps in a tent on the grounds. She occasionally teases her brother in a friendly manner. Her self-reliance is encouraged by her mother, Kana Akabane.
In appearance, Naru has aqua blue eyes and short aqua blue hair. Her signature outfit features a white cotton beanie with a blue cotton ball and a white-and-blue striped border. She typically wears a short-sleeved dress shirt, dark and light-blue pinstriped trousers with dark blue pockets, dark blue suspenders adorned with an 'N' badge, and light blue slip-on shoes. A gold bracelet is her regular wrist accessory.
Naru maintains close familial bonds, especially with Aiger. She actively monitors his activities and updates him on Beyblade news, though her persistence sometimes annoys him. Their mutual affection remains clear despite minor friction. Her father, Taiga Akabane, is a Master BeyTrainer who pioneered Turbo Beys and created Wonder Valtryek for Valt. Her mother, Kana, shares Naru's emphasis on independence. Beyond family, Naru befriends Toko and Nika Aoi (Valt's siblings) at Beigoma Academy, often conversing with them or observing Beyblade training sessions.
Her background originates on the family farm, where she assists with chores. She later accompanies Aiger to Beigoma Academy, initially withholding her own enrollment until revealing it after his battle with Fubuki Sumiye. Throughout Aiger's journey, Naru provides consistent logistical and moral support: guiding Valt to the nearest city, cheering during Aiger's battles, alerting him to strategic opportunities (like Fubuki meeting Lui), defending him against mockery, assisting in blueprint designs for training equipment, and reminding him of match rules to prevent disqualification. She participates in daily activities such as feeding animals at the academy ranch and household chores like washing dishes.
Naru experiences notable moments, including frightening confrontations with dark aura bladers like Suoh and Houi, though she eventually befriends Houi. She reacts with disgust to Houi's sports drink during training and witnesses critical events like Kurt and Valt's match, which she shows Aiger via tablet. Her quotes reflect her persistent and observant nature: "Naru wants too, Naru wants too," "Don’t get lost again," "Weird, he’s talking to Achilles again," "After all the trouble I went through to collect that data, this is what you say?" and "Aiger, you're great."
Trivia notes indicate her Japanese name 'Naru' translates to 'change' or 'to become,' possibly reflecting her tendency to insert herself into situations. Her birthday coincides with St. Patrick's Day.
