TËЯRA is the two-person group consisting of former BEMANI mainstays NAOKI and jun, who joined the DanceDanceRevolution series in 2002 for DDRMAX2: DanceDanceRevolution 7thMIX. The duo have worked together over the past 10 years on many songs, almost all of them exclusively under the TËЯRA alias. They have appeared in nearly every BEMANI series since their debut. jun almost always writes the lyrics, as well as does the vocals, on the songs by herself. In beatmania IIDX and pop'n music, she also frequently did the composition of the songs, with NAOKI doing the arrangement. In GuitarFreaks & DrumMania, NAOKI was usually the one in charge of composition, as well as performing on the guitar.
The group released their first album, RЁVOLUTIФN, on March 11, 2005. In late 2010, an official UStream stream from KONAMI revealed that a second album was in the works; ЁVOLUTIФN was released on September 7, 2011.
TËЯRA's official website was shut down in late 2009, but profiles of both members still remain on BEMANI MUSIC FOUNDATION, as well as a page to order ЁVOLUTIФN. Following the duo's retirement from KONAMI in 2013, TËЯRA's profile was removed from the BEMANI Fan Site's artist listing. TËЯRA then composed new songs for CAPCOM's crossbeats music game series until the series' end in 2018.
- switch is the only original song credited to TËЯRA in BEMANI that does not involve NAOKI in some way on it.
