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.), also known as Ore, Twintail ni Narimasu. or in its short form OreTwi(俺ツイ), is a Japaneselight 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 began airing in Japan on October 9, 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 power", 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

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, Thouars 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 heriones, 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 over protective of him although this is later discovered to be because of her massive crush on him. Aika has 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 is mostly hated by the populous, until later when Tail Yellow joins the team.

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.

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.
