Question: Who was previously in a boyband, Dani Filth or Takahiro Moriuchi?
Context: 5...GO is an album by South Korean rock band F.T. Island.  It was released on 13 May 2015.  The album was released to celebrate the band's fifth anniversary in Japan.  The title track "Primavera" is a collaboration with Japanese rock singer Takahiro Moriuchi from One Ok Rock. Cradle of Filth was formed in Suffolk, England in 1991.  The band's original members consisted of vocalist Dani Filth, guitarist Paul Ryan, keyboardist Ben Ryan (Paul's brother), bassist John Pritchard and drummer Darren Gardner.  With this line-up, Cradle of Filth recorded a demo in 1992, titled "Invoking the Unclean".  Soon after, they recorded their second demo, "Orgiastic Pleasures Foul" with new guitarist Robin Eaglestone (aka Robin Graves) and new drummer Was Sarginson.  Robin left the band shortly afterwards, but following the departure of John Pritchard, Eaglestone returned to take his place as bassist.  Guitarist Paul Allender joined the band at the same time.  Following these changes, another demo was recorded, titled "Total Fucking Darkness" (released commercially in 2014, bolstered with rehearsal sessions and a surviving track from the abandoned "Goetia" album).  Sarginson left the band soon after, paving the way for the entry of drummer Nicholas Barker. Devilment are a British heavy metal band originally formed in late 2011.  The band experienced problems finding a stable vocalist until Dani Filth from the extreme metal band Cradle of Filth joined.  They released their first studio album, "The Great And Secret Show", on 3 November 2014. The Gospel of Filth: A Bible of Decadence & Darkness (formerly known as "The Gospel of Filth: A Black Metal Bible") is a book by Dani Filth and Gavin Baddeley, documenting the history of the band Cradle of Filth and straying further afield to explore their influences and "lay bare the fascinating underworld of contemporary culture". Dani Filth (born Daniel Lloyd Davey) is the lyricist, vocalist and founding member of the metal band Cradle of Filth. News, stylized as NEWS, is a four-member Japanese band consisting of Keiichiro Koyama, Takahisa Masuda, Shigeaki Kato and Yuya Tegoshi.  The group's name is an acronym based on the cardinal directions (North, East, West, South).  Formed in 2003 by Johnny Kitagawa as a nine-member group under the label Johnny's Entertainment, NEWS released a promotional single "NEWS Nippon" (News ニッポン , News Japan) , which was used for the World Cup of Volleyball Championships.  In 2004, Takahiro Moriuchi (present-day Taka of One Ok Rock) left the group and the remaining eight members released their debut single, "Kibō: Yell" (希望 ~Yell~ , Hope ~Yell~) , which debuted atop the Oricon charts. One Ok Rock, stylized as ONE OK ROCK (pronounced in Japanese as "one o'clock"), is a Japanese rock band formed in Tokyo, Japan in 2005.  The band currently consists of Takahiro Moriuchi (vocals), Toru Yamashita (guitar/leader), Ryota Kohama (bass), and Tomoya Kanki (drums). Takahiro Moriuchi (森内 貴寛 , Moriuchi Takahiro , born April 17, 1988 in Tokyo) , known professionally as Taka, is the lead vocalist of the Japanese rock band ONE OK ROCK.  Prior to this, he was in the boyband NEWS throughout 2003 until he left the group and the agency.  Taka is the lyricist and composer of his band. The Principle of Evil Made Flesh is the debut studio album by English extreme metal band Cradle of Filth.  It was released on 24 February 1994 through Cacophonous Records, following three demos released between 1991 and 1993.  The album's sound is significantly more raw than on subsequent releases, and frontman Dani Filth's vocals differ from his later style and technique.  The album is a then-unusual hybrid of gothic metal and black metal.  This would be the only album featuring guitarist Paul Ryan and keyboardist Benjamin Ryan; guitarist Paul Allender also left the band at this point, but returned five years later for "Midian". Japanese rock band One Ok Rock has released eight studio albums, two EPs, 22 singles, seven video albums, six cover versions, and 32 music videos.
