Iki Nuki Night Party 1
The Iki Nuki Night Party page has a general description of this event.
This was the first event, so Sayaka was still trying out various ideas for this event.
I went because Takahira Jun was a guest, and this was her first event in around two years (since the breakup of Kira Kira Melody Gakuen).
Also this was Sayaka's birthday, so there was a "surprise" birthday cake for her.
