^^How do you know
for sure she's pure hetero? . ...nevermind.
What would be wrong with her becoming Mr. Joshi Puro? She's a freakin' legend.
Besides all that, sometimes a girl feels like putting on a suit and looking as cool as possible without being the comparatively very vulnerable feminine ideal (especially in Japan).
Speaking of the legend of Shinobu;
In this photo she looks like Shinobu Kandori.
I noticed Emi has done lots of Kandori-style lately, wearing men's clothes for formal event etc.
It's more of a Jackie Sato sauve/cool-ness than a balls (no pun intended) out Shinobu politician brashness. And let's not forget Jackie's butchness begot Shinobu's.
Cool as the other side of the pillow.
