If kaga is Kira does that make me Misa?

I don't think being my Misa would be a good thing.

Unless you're content with halving your lifespan twice and letting me manipulate you into killing just about anyone I want all while I'm only pretending to care about you as a person.

...Which, if you're my Misa, you would be perfectly content with, I suppose.
