## Plot

Soji Mitsuka, an ordinary high school boy, has an obsession for twintail hair. He meets a mysterious girl named Twoearle, who is from a parallel world, when monsters appear in his town and declare that all twintails in the world belong to them. These monsters feed off "attribute strength", the spiritual energy of humans. Twoearle entrusted Soji with Tail Gear, imaginary armor initiated by powerful twintail attributes. With the armor, Soji transforms into a girl and twintail warrior (ツインテイルズ関係者, tsuinteiruzu kankei-sha) branded Tail Red, to protect Earth.

#### Soji Mitsuka (観束 総二, Mitsuka Soji) / Tail Red (テイルレッド, Teiru Reddo)

    Soji (male) Voiced by: Nobunaga Shimazaki (Japanese); Austin Tindle (English)
    Souji (female)/Tail Red Voiced by: Sumire Uesaka (Japanese); Bryn Apprill (English)
    A gentle-natured freshman of Yōgetsu Private Academy obsessed with the twintail hairstyle. He later meets a mysterious beautiful girl named Twoearle, who appears before him from a parallel world. At the same time, monsters begin to invade town and attack everyone. In the midst of the chaos, Twoerle entrusted him with attribute power, thus suddenly transforming him into a twin tail warrior girl, known as Tail Red. Due to his alter ego (Tail Red) becoming popular quickly after his debut and him being the first twintail warrior to transform, he is the leader of the Twintails. His weapon is Sword of Fire, Blazer Blade (炎の剣ブレイザーブレイド, Honō no Ken Bureizā Bureido). In volume 4, he gained two power-up forms: Riser Chain and Faller Chain. He later gains Ultimate Chain, after regaining his Twintail Elémera, which he lost to Tyranno Guildy.

#### Aika Tsube (津辺 愛香, Tsube Aika) / Tail Blue (テイルブルー, Teiru Burū)

    Voiced by: Yūka Aisaka (Japanese); Sarah Wiedenheft (English)
    A freshman of Yōgetsu Private Academy and childhood best friend of Soji. She treats him like a little brother and is rather overprotective of him although this is later discovered to be because of her massive crush on him. Aika has a complex with her body, especially with her flat chest. She has a violent attitude toward Twoearle who often teases her about her chest. When she first became a Twintail warrior, she was mostly hated by the public, until later when Tail Yellow joins the team. Aika has an outstanding ability of fighting as she was raised by her grandfather with martial arts. She is known as Tail Blue when she transforms, and her weapon is Spear of Water, Wave Lance (水の槍ウェイブランス, Mizu no Yari Weibu Ransu). She also gains Eternal Chain.

#### Erina Shindō (神堂 慧理那, Shindō Erina) / Tail Yellow (テイルイエロー, Teiru Ierō)

    Voiced by: Chinatsu Akasaki (Japanese); Mikaela Krantz (English)
    A sophomore of Yōgetsu Private Academy and the Student Council President. Known as Tail Yellow in her transformed state, her weapon is Gun of Lightning, Vortex Blaster (雷の銃ヴォルテックスブラスター, Kaminari no Jū Vorutekkusu Burasutā). She is a closet masochist and exhibitionist, and gets aroused when Soji calls her name (which usually triggers her to call him master). When she first became a Twintail warrior she was a completely reckless fighter because of her maschostic ways. She was the only one of the twintails who at first could not use her power because of her denial of twintails, until Soji gets her to accept them. Unlike Soji and Aika, Erina's twin-tail warrior form makes her whole body look a lot older and has a more well endowed figure. She also gains Absolute Chain.

#### Twoearle (トゥアール, Tuāru) / Tail White (テイルホワイト, Teiru Howaito)

    Voiced by: Maaya Uchida (Japanese); Morgan Garrett (English)
    A mysterious girl who comes from another planet and the first Tail Warrior. She enjoys teasing Aika with her large bust and often ends up grievously injured for it. She fell in love with Soji at first sight and openly tries to seduce him with his mother's approval. After Soji defeats the first wave of attacks from the monsters, she joins Yōgetsu Private Academy as a student and calls herself Soji's relative. Before arriving on Earth, she was the original Tail Blue but gave up her twin-tail hair style to make the Tail Red gear after her world lost all attributes. She felt immense regret and shame for not saving her world and retired from fighting as she felt she was no longer capable of defeating the Ultimegil and passed her mantle on to Soji, feeling he would do much better than she did. After seeing Soji's determination and willingness to protect the innocent, she was happy knowing she made the right choice on appointing her successor. She was able to regain her twin tail form and became Tail White but her form is limited to a few minutes. Though it compensates by being more powerful than Soji's Tail Red in its Ultimate Chain form.
