PSYCHO type Deformity (サイコ type Deformity) disbands
Around this time, there were rumors that vocalist NAO (ナオ) moved to Tokyo (東京) and formed a band with ex-PUELA (ピュエラ) guitarist Krus (クルス) on support(?). It's unclear if this actually happened, as NAO (ナオ) was again in Nagano (長野) by the next year.
[Former guitarist?] Akino (秋乃) forms solo project PSYCHO type MINORITY.
PSYCHO type MINORITY changes to a formal band, renames to Psycho type Deformity, and inherits all songs from TRESOR (トレゾア).
It's unclear if/how the newer band is related to the original.
Guitarist Akino (秋乃) was originally active in the visual scene in Nagano (長野) around the turn of the millenium, and re-joined the scene a decade later. His bands after re-joining were TRESOR (トレゾア) and Psycho type Deformity, both of which are names of bands that existed in Nagano (長野) at the same time that Akino (秋乃) was originally active.
Since both names are fairly unique, I assume that Akino (秋乃) was a member of both original bands, and then reused their names years later. However, neither band is known to have had a member named Akino (秋乃), so details are murky at best.
PSYCHO type Deformity (サイコ type Deformity) was a visual kei band in Nagano. They were active from 1999 and are now disbanded.
