She has been to stuff since her graduation. Firstly, she went to Risa's BD event and I spent several hours at the same cafe as her and Ozeko (their table was a bit further away) waiting for it to begin. Yes, greeted her very shortly. During the show she was on the 2nd floor together with Ozeko and Musubu who arrived by herself. She also came to both CG events I believe (not sure about the 5th anniversary one but pretty sure she came to the disbandment one). I think she also showed up for something JJ related but can't remember what it was. That said, only for Risa's BD event when she was on the 2nd floor watching was she actually visible though, for the others I think she was just backstage-ish. After Risa's BD event ended she actually stood there for a while looking at the audience before following ozeko and musubu back (felt very much like she was looking in this direction but unsure ;_; )
