Futaba and Akira

Here's a pic of Akira with his little sister Futaba.
It's been a very long time since I've drawn Fuu-chan.  Some of y'all may remember her from this old-assed yonkoma.

 
I've been contemplating whether or not to keep her in the story (the one I'm not writing...).
She serves as another yandere and a foil to Mia, but not much else.
