>>13956186Off the top of my head I can think of they have collabed with in terms of JP females Chigusa, Ange, Rin, Chima (just about to), Sukoya, Amamiya and Levi. In terms of JP males Oliver, Lauren, Kanae, Mayuzumi, Belmond, Kanda, Nagao Kei.
So really it's about even between males and females from the JP branch they have collabed with.
