In an interview on Nack5 FM Triangle Super Audition, Toshiya explains that the band's name, which is an archaic word for "February", was one of the names considered for DIR EN GREY.
Kisaragi was one of the earlier bands of DIR EN GREY's bassist Toshiya. They formed in the later half of his second year in high school (October 1993 to March 1994).
During their third year (April 1994 to March 1995), they perform at the school's culture festival. This was the first time Toshiya took the stage. They also performed at a live house about a month later.
