D4DJ Groovy Mix Marks 6th Anniversary with World Dai Star Songs and SP Gacha
The anniversary update mixes a cross-title song batch with a four-round SP gacha, so Groovy Mix is using its sixth-year window to pull in World Dai Star and VIRTUAL GIRL @ WORLD'S END material at the same time.
Reporting from 1 source: Nijimen.
D4DJ Groovy Mix confirmed four songs from World Dai Star: Yume no Stellarium for implementation. "Sirius no Kagayaki no Yō ni" is added September 25 at 18:00, while "I Wanna," "Zettai! Niederrhein Sengen♡," and "Dennō Spectacle" arrive October 1 at 18:00. The 6th Anniversary Event Gacha "Harmony Disc 1st SESSION" starts October 1, with 32 SP members appearing across four rounds, and a VIRTUAL GIRL @ WORLD'S END revival runs October 1 to 16.
D4DJ Groovy Mix is spreading its sixth anniversary across several weeks rather than a single day. A pre-opening login campaign runs through September 30, handing out up to 10 Gacha Ticket 2026, and the 6th Anniversary Event Gacha "Harmony Disc 1st SESSION" opens October 1 with eight featured SP members and 32 total SP members planned across four rounds.
Alongside the gacha, four World Dai Star: Yume no Stellarium songs join the game. "Sirius no Kagayaki no Yō ni" is playable for free from September 25, while the other three unlock through paid release on October 1 and stay playable for a limited one-year period.
