Haruka (ハルカ) is Yellow Mask of the Maskmen. She is also one of the main protagonists.
When she was a child, Haruka was raised in a family of ninjas, brought up to carry the tradition at the cost of a happy childhood. Having been forced by her father to ditch all feminine things to focus on her ninjutsu, she grows to be tomboyish and a fierce fighter as well. In addition to that, she is very intelligent and loves to dance as she tutors a young girl who is unable to afford dance lessons.
Haruka and her comrades teamed up with the other nine Sentai to stand behind the newest Sentai, the Turborangers, as they faced off against the Hundred Boma Tribes.
Yellow Mask is among the Sentai warriors seen in a clip-show when Miku Imamura (MegaPink) lectured Sae Taiga (GaoWhite) about the past female Super Sentai warriors and their shared mastery of disguise and habit of changing their clothing in the blink of an eye, something that Sae had never done before.
Years later, Haruka fought alongside not only her own team, but every single Sentai ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. After decimating hundreds of Gormin and their Zgormin commanders, Kaijou noticed the fleet moving towards them, gathering all the Rangers together and ordering them to sacrifice their powers to wipe out the first invasion's armada. The Yellow Mask powers are later used by Luka Millfy via the Ranger Keys.
After the Zangyack's final defeat, Marvelous returned the Ranger Keys to their original owners. It is assumed Haruka and her teammates regain their powers once again.
