Solo 3D event yeah? I know she had a birthday 3D live last year, plus her own live concert. But when it comes to appearance in 3D streams? I'm quite sure that belongs to Gura. No, I'm not even coping. Here are all her 3D appearances just for this year (and I'm not even gonna include those "big" events like 4th Fes):the Holo EN that does the most 3D events still streams without major changes (Mori Calliope)
Fauna 3D showcase, Shion anniversary live, HoloSummer opening stream, Miko live, Okayu birthday live, Pekora birthday live
