wink wink - #X (Devil Summoner: Soul Hackers)

Vocals by: wink wink

Lyrics by: Kazuyuki Yama

Music by: Ryota Kozuka

Note: It is unknown if the singer has more work or not (if wink wink isn't a band name), and I likely suspect this was used as a one-off pseudonym for the project, which is standard among Japanese (?) singers.
