ティッシュ姫 (Tissue Hime)

Popular Nico Video musician, known for his very skilled bass guitar playing and on-stage cosplay as Nagato Yuki.

He is generally considered to be a 'Trap'.

A 'Trap' is a well recognised cultural phenomena in Japan (and elsewhere) where 'boys' dress convincingly as 'girls', and Cosplay can feature heavily as part of this transgenderist cross-dressing.
