Guitarist miya secedes.
MAO joins as support drummer.
According to the band's official history, they “meet” guitarist itsuki and drummer gutti. I've never heard of gutti again, so I can only assume that he did a one-off live as support drummer. itsuki wasn't mentioned in the band's August 2004 flyer, so I'm guess he didn't actually join the band until their September sponsored event.
For some reason, itsuki is absent from an August 2004 flyer. However, he was posting in the band blog as late as December that year, and was mentioned as a member when the band announced their activity pause. So, I'm not sure if he temporarily left the band around this time.
First free oneman is held at Akasaka (赤坂) L@N. Guitarist itsuki joins(?).
Former guitarist miya re-joins as bassist.
Bassist C'La secedes(?). (Not sure of the date: he's on an August 2004 flyer, but is not listed as a member on the band's website in October of 2004. However, he and C'La joined 響~hiViki~ in November 2004.)
First sponsored event is held at Akasaka (赤坂) L@N. An unknown CD is freely distributed to the first 20 attendees.
Unofficial last live is held.
