Yurijuujidan was formed in 2000 and consisted of Kazuki, who went under the pseudonym Chris Darkschneider, on vocals, Mask on guitar and Kurt Burton (Kuruto, ex-Pleur) on bass. The band's name is a wordplay relating to the Rosicrucian Order, and can be translated as “Lilycrucian Order.”
The band only managed to record one maxi-single: Yurijuuji no kakusei. It was produced by Kazuki and Hirai Kouichi, who had already worked with Raphael before. It contained three tracks and the instrumental version for each song.
Sadly, on November 31, 2000 Kazuki suddenly passed away. That meant an end to Yuurijuujidan, and an end to Raphael. So, their maxi single Yurijuuji no kakusei was released only after Kazuki's death, on April 7th, 2001.
