Mika and Yuu - Angel and Demon

I really enjoyed the last chibis so I wanted to draw more
Last time Krul turned out so cute and I wasn't sure about Mika... now Mika turned out SO LOVELY and Yuu is kinda meh One of them is always trying to bother me
I wanted to draw Chibi Demon Yuu for awhile now and thought about that demon and angel comparison. And I really enjoy including Mika everywhere I can These roles suit them very well, I think!
Maybe I should change that background...
