TailYellow is the most formidable and impressive looking of the Twin Tail Warriors. This because she is older and wears the Tail Gear that is more armored and more technically advanced. TailYellow has an fully developed adult female body of about 21-22 years old, being both tall and well proportioned. She has a large, prominent bust. Her hair color is that of a bold, natural blonde. She wears her blonde hair with bangs that droop across her forehead and encircle her cheeks, and thin twin tails that fall below her knees, and end in corkscrews. TailYellow has a mature, somewhat pointed face, with adult-like narrowed eyes, mountain green in color. Her skin tone is medium to tan beige, looking like she has a year round tan.

TailYellow's Tail Gear looks a bit different from the others, since her Tail Gear is of a more recent design. It looks more like a Battle Maiden's professional outfit instead of a girl's swim suit. It is heavily armored, with massive plates on her shoulders, arms, and legs. Her hips have 'saddlebag' plates, and her boots have side armor. The two armor plates on her hips, and the two armor plates on her shoulder blades can pivot upward and lock into place, giving her the appearance of having wings on her back and hips. She has black gloves protecting her hands. The Yellow Tail Gear can do something unique; it can be removed from TailYellow's body by remote control, leaving her wearing what looks like a yellow bikini swim suit, and can reassemble itself into a mobile battle platform, complete with armor and weapons, than can be operated by remote control. As her weapon, TailYellow can command her armor, either while mounted on her body, or removed as the mobile platform. She also commands a hand weapon that resembles a high-tech Saturday Night Special pistol.


One of the Twin Tail heroines, she is in real life a petite 16-year-old sophomore of Yōgetsu Private Academy, and the Student Council President. So unlike her unassuming, child-like day-to-day self, TailYellow is an adult closeted masochist and exhibitionist, and gets excited when TailRed calls her by her pet name (which usually triggers her to call him 'Master' ). When she first became a Twin Tail Warrior, not being very adept, she could not operate her Tail Gear or weapons to any useful degree. Later, she becomes a completely reckless fighter because of acknowledging and applying the masochistic streak in her adult personality.

In battle, she sometimes decides to almost completely disrobe ( she sheds the Tail Gear, revealing and wearing only an outfit similar to a white bikini swimsuit ), and allows the Tail Gear to reassemble into a remote-controlled mobile battle station. TailYellow was the only one of the Twin Tail Warriors who, at first, couldn't use her power because of her lack of personal motivation, until Soji reasons with her about an alternate method that would activate the Tail Gear. Soji explains that TailYellow's admiration of and strong desire to be a heroine would be enough to spur her on.

Unlike TailRed and TailBlue's transformed appearance, TailYellow's Twin Tail Warrior form makes her look older ( a 21+ adult ), and although she does not change gender, but remains a female bodied adult, she does eventually display the more adult virtues of loyalty, teamwork, and self-sacrifice. Known as Tail Yellow in her transformed state, her weapon is Gun of Lightning, Voltage Judgement, Vortex Blaster (雷の銃ヴォルテックスブラスター Kaminari no Jū Vorutekkusu Burasutā).

In Volume 7, she gains the upgrade of Absolute Chain.
