MEBIUS forms in Tokyo (東京)東京.
1984-10-00

It's possible that the October 1984 date is when they formed rather than when they changed their name. In any case, it seems like they started as MEBIUS in 1984 and changed their name within the same year. It is presumed that the lineup was the same between the two names, but this is unconfirmed.

MEBIUS changes their name to DEMENTIA (ディメンシア).
