"s.d.z." or "s.d.z"
- I checked AC bm 3rdMIX, completeMIX, FINAL, III series, and CS APPEND 3rdMIX. All of them are "s.d.z" (two periods).
- The last appearance for s.d.z. was in beatmania (USA), where I think it was shown with three periods. I have no way to check it, but we usually how the title is shown on its last appearance for the pages themselves. If you or somebody else can check how the title is shown in beatmania (USA), please post here. --FinalOffset (talk) 19:20, 19 September 2017 (UTC)
