>>82089051ERM ACKSHUALLY since Mata was in that middle collab too she's also pulled that off. I think Kuro too? I'm not 100% but when Kuro collabed with Giri I think Michi was there in the background. If she was then yeah he also did all 3 forms.
Now if you wanted to make the argument that Giri did this all under a single identity, then yes she still holds that unique distinction. Kuro and Mata specifically never collabed with Mika, they did it as Nina and Mysta.
