Tei☆in! (てぃ☆イン!, pronounced as Tii☆in!) is the odorite duo of Fine (ファイン) and Tsuruti (つるてぃ). They are well-known for their snappy and witty choreography. They started in 2011 and is now considered an inseparable team.
Fine is considered the "Leader of Tei☆in!" and is responsible for the choreography. While Tsuruti is called the "Glasses of Tei☆in!". Fine is always on the right side of the screen and Tsuruti on the left.
Although each of them has their own Mylists, their dances are uploaded by Fine. Their choreography can also easily be danced in solo because they are usually just a mirror of each other. Tei☆in!, however, has never danced in solo.
Their first dance cover is of the song "Twinkle" by the producer Junky. Which somehow became popular, reaching more than 100k views.
By 2012, their dance cover for the short version of "Tell Your World" became their most iconic dance cover, reaching 500k+ views and stayed in the Odottemita Ranking for months. Neglecting to post a full version of the dance, other odorite were influenced to perform full versions with their own interpretation. However, in spring 2014, Tei☆in! collaborated with the American odorite duo Ari 。Ki to perform a full, 4 person version of "Tell Your World" live at Cho Party 3.
Tei☆in! also collaborates with Melochin. Their collaboration videos usually become viral, especially their choreography of "Mousou Zei," which reached the No. 1 spot in the Odottemita Ranking in 2013.
