Two birds

Tokoyami is training outside and dark Shadow accidentally knocks a bird's nest down. Upon picking up the nest he finds out that there was a bird in it who's wing got injured. He takes it to recovery girl who figures out it's a sprained wing. Until it's healed Tokoyami plans on taking care of it. He puts the nest in a shoe box and explains to the bird that the box is it's new home. The next day he comes back from class and finds a naked boy in his room curled around the shoe box. Tokoyami yells and people rush to see what's wrong. The male has wings on his back that look exactly like the little bird's wings.
