Drums: JOE (sex MACHINEGUNS → DASEIN → SEX MACHINEGUNS、 ELLEGUNS → J-P-K PROJECT → CYCLE)
This band was formed by former Sex machineguns drummer Joe and former R*A*P vocalist Ricky.
Joe was originally from Sex Machineguns but had to leave for a while due to Spinal disc herniation, after his sucessful recovery rehabilitation he had to change his way of playing the drums (not using so much force. Although he reverts back during lives) and he formed DASEIN with his friend Ricky.
After DASEIN was disbanded Joe rejoined Sex machine guns for a while and is now in CYCLE together with former Sex Machineguns members Murai Kenjirou and Panther.
Ricky became vocalist for Rider Chips, Chrome Shelled and is currently working on his solo project Dotto.～独人～.
Joe and Ricky are very good friends and ocassionally go out eating/drinking together. They have also played some old DASEIN songs during lives together long after DASEIN was disbanded.
There is very low chances of DASEIN being reformed, although there is chanses of hearing their songs performed live since both have expressed themselves willing to do so.
Ricky is now part of THE MICRO HEAD 4N'S.
