Mai Hakua (伯亜 舞 Hakua Mai): Ryouga Hakua's five-year-old niece. Ryouga's brother and sister-in-law died in a car crash, leaving Mai in Ryouga's care. Mai thinks of Ryouga as a father and always cheers him on when he fights as AbaRed. Starting at the end of ep. 39, the mysterious girl chooses Mai to be the only one to see her. In ep. 41, a virus transforms human people into Barmia Soldiers and Mai was infected as well. The mysterious girl warns the Abaranger that the Barmia around her are Mai's friends, but Mai was cured when her Dino Guts awoke when she cheered for the Abarangers after seeing Ryouga and the others in danger from the Barmia. After the end of the series, Mai stayed in California with Ryouga.
Mai also appeared in Tokusou Sentai Dekaranger vs. Abaranger, where she was auditioning for a part which Ryouga had to call to check up on as part of a promise which occurred during a fight and this distraction angered DekaRed for awhile that it caused Ryouga to get into an argument with him. Mai later showed up during both teams' victory meal.
