Someone mentioned that Reine and Irys roommates know each other from long ago and that they sang songs together a while back, but I didn´t get any more info on it so I tried to do my own reseach. First time really looking into Reines roommate as well, past the obvious daugher of Indonsian Oligarch stuff.
So while both Reine or rather Kimunyu and namirin have been utaite since 2010 (I didn´t know Reines history traces that far back as well) and most certainly were aware of each other in that rather small circle after all, I cant find a song that features them both. Or at least Kimunyu must have known about namirin, since she was/is huge in that scene, but I didn´t find any direct interaction. The only thing I have is that namirin is linked on her channel.
Does that mean anything? Maybe, maybe not. I will add that she follows Keekihime on twitter and probably some more roommates of ID girls I dont recognize but she doesn´t follow namirin on twitter as well.
