SE - lift me back up

I don't understand about complementary colors
And what they say
Side by side they both get bright
Together they both get gray...

It's as if, every time I think they've topped out their OTP potential, they find a new way to do the impossible, see the unseeable, and climb to new levels of glory. Thank you, Ohkubo-sensei and BONES.

This quickie sketch is for all those of us who've been teased to the point of Black Blood madness by the last few episodes... Probably scrapping it later.

And it's dangerous work
Trying to get to you too
And I think if I didn't have to
Kill, kill, kill, kill, kill, kill myself doing it
Maybe I wouldn't think so much of you...
