Will Yuuji be able to find his place in the world before he ceases to exist?

Yuko's too weak and uncoordinated to straight-up kill Momo, even if she wanted to, but she can't just be buddies with this generous magical girl, either–she has to break the curse on her family somehow. What's a demon girl to do?
