méffist forms in Gunma (群馬) some time in 1998 (or possibly earlier). At the time, the band has three members--I'm not sure which ones, aside from vocalist SHIN.
An important announcement is made. (Not sure what the announcement was; possibly the joining of two additional members, or that the band would join Matina.)
At some point, two members join méffist, leading to a 5-member lineup. I'm unsure which members joined, or when they joined--I've arbitrarily put this date, as they had an important announcement, and their DT (which was released 2 months later) featured 5 members.
