Ako, born October 24, 1972, she was a bright and cheery Miharakita High School senior. She wanted to marry a rich man and called her superior officer Choukan Odagiri "Granny". She first thought of Jetman as a part time job paying ¥1500 an hour, but her first battle awakened her sense of justice and made her realize that she must fight as a warrior. Her best friend is her classmate, Kyouko. Ever since she was a little girl she had this wonderful teddy bear she named Putan. Deciding one day that a High School Junior should not be carrying around a teddy bear any longer, she threw him away. But the Vyram threw a bio changer into a pile trash the teddy bear was in, and was accidently used in the creation of a monster, Garbage Jigen. The monster, however, had the soul of the teddy bear, who thought Ako was his mother. He died saving her from Maria. Later in the series, Ako met Dan, the youngest of a group of the Dimensian Warriors who came to Earth with Jet Garuda. Their own world Dimensia had been destroyed by the Vyram, and they hoped to tip the balance in favor of the Jetman, and stop the Vyram. Dan pretty much had a crush on Ako from the moment he saw her but he drove her crazy. When his friends were killed by Radiguet, Dan went into battle alone. He was mortally injured and died in Ako's arms. That was when she realized she loved him. Three years after the Vyram were defeated, Ako had become a singing idol and made it happily to the wedding of her dear friends.
