Gonna be the Twin-Tail!! (俺、ツインテールになります。, Ore, Tsuintēru ni Narimasu., I Will Become a Twintail.), or in its short form OreTwi (俺ツイ), is a Japanese light novel series written by Yume Mizusawa and illustrated by Ayumu Kasuga. Shogakukan has published twelve volumes under their Gagaga Bunko imprint since June 2012. An anime adaptation produced by Production IMS aired in Japan from October 9, 2014 to December 25, 2014.


Sōji Mitsuka is an ordinary high school boy who has an obsession for twintail hair. One day he encounters 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 Sōji with Tail Gear, imaginary armor initiated by powerful twintail attributes. With the armor, Sōji transforms into Tail Red, a twintail warrior (ツインテイルズ関係者, tsuinteiruzu kankei-sha), to protect Earth.


Twintail Warriors[edit]

Sōji Mitsuka (観束 総二, Mitsuka Sōji) / Tail Red (テイルレッド, Teiru Reddo)
Voiced by: Nobunaga Shimazaki (Japanese); Austin Tindle (English) / Tail Red Voiced by: Sumire Uesaka (Japanese); Bryn Apprill (English)
The main protagonist, a gentle-natured 15-year-old freshman of Yōgetsu Private Academy, who is obsessed with the twintail hairstyle. One day, he encounters a mysterious beautiful girl named Twoerle, who appears before him from a parallel world. At the same time, monsters begin to appear in his town, and they start attacking the citizens. 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 Vol 4, he gained two power-up forms: Riser Chain and Faller Chain. He later gains Ultimate Chain (his strongest form) after regaining his Twintail Elémera which he lost to Tyranno Guildy previously.
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)
One of the heroines, a 15-year-old freshman of Yōgetsu Private Academy and childhood best friend of Sōji. She treats Sōji 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 Twoerle 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. In battle, 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). In Vol 8, she 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)
One of the heroines, a 16-year-old 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 Sōji 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. Also she was the only one of the twintails who at first couldn't use her power because of her denial of twintails until Soji gets her to accept them. Unlike Sōji and Aika, Erina's twin-tail warrior form makes her look older and has a more well endowed figure. In Vol 7, she gains Absolute Chain.
Twoerle (トゥアール, Tuāru)
Voiced by: Maaya Uchida (Japanese); Morgan Garrett (English)
Another heroine, a mysterious girl who comes from another planet. She enjoys teasing Aika with her large bust and often ends up grievously injured for it. She fell in love with Sōji at first sight and openly tries to seduce him with his mother's approval. After Sōji defeats the first wave of attacks from the monsters, she decides to transfer into Yōgetsu Private Academy as a student and calls herself Sōji'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 its attributes.
Īsuna (イースナ, Īsuna) / Anko Īsuna (善沙 闇子, Īsuna Anko) / Tail Black (テイルブラック, Teiru Burakku) / Dark Grasper or Dark Glassper (ダークグラスパー, Dāku Gurasupā)

In battle, she is known as Tail Black. Her weapon is Darkness Grave Moebius, and her weapon when she was in the Evil Gill was Sickle Grave of Darkness.
