Satan's Friend and an Illusionist Back From the Depths of Hell

Mukuro seems to have fallen for Tsuna's childhood friend, Azulia. He shows more emotion around her and clings to her a lot. Azulia doesn't know what to make of the situation. She doesn't think of Mukuro as annoying, she doesn't hate his company(even though Tsuna is afraid of it), and she's actually quite fond of him also. But are these feelings like Mukuro's?
