Reiji Sakurai (born January 26th, 1986) was for a while a frequently appearing vocalist in Bemani, who made his first appearance in 2004 when he won the BEMANI 2004 Vocalist Audition, alongside Kanako Hoshino and the members of BeForU Next. He then made his first appearance in pop'n music 12 いろは with the song For Dear～. After that, he became fairly active in the pop'n music and GuitarFreaks & DrumMania series, appearing in both games for several years after. Originally he was credited for songs under his original name, but eventually changed it to RayZY, which stuck for the rest of his BEMANI tenure (with the exception of White Sketchbook).
Outside of BEMANI, Reiji is a composer, guitar player, lyricist, and vocalist. He used to be a part of a band called Gylay up until March 28th, 2009. Reiji left Konami in the late 2000's and is currently signed on with Japanese record company BIG TREE RECORD, who have provided jubeat plus and REFLEC BEAT plus with licensed songs. He's also worked on kors k's record label, QUADROID YUJI.
- Soon after he won the BEMANI 2004 Vocalist Audition, pictures of Reiji with a pierced face with a chain attached to it were taken. This was digitally removed from photos before they were sent out to the public because, according to the pop'n music staff members, they "didn't want his pierced face to scare children from playing the game".
