What was Natsume hiding in her closet in episode 11? In episode 11 of Tokyo Ravens, what was Natsume hiding in her closet?
It was never shown in the whole series, but we can make some intelligent guesses. Here are the list of things Natsume hides:


She is a girl. No one except Harutora knows she is a girl.
She is the controller behind Hokuto.
She is obsessively in love with Harutora.


So based on these things, it could be 


Girl clothes, cosmetics, girly things, etc. 
Clothes and kit that Hokuto uses.
A whole collection of things related to Harutora, maybe during his time with Hokuto. Pictures, memorabilia etc..
