Manga by author Ninomiya Ai

From Yen Press: A disillusioned young man in search of "something" stumbles into the weird and wacky world of Wonderland, where, as "Alice," he is thrust into a murderous game of "Kill the White Rabbit" by command of the ruler of the land, the Queen of Hearts. But while Alice rails against the role that has been forced upon him, he has little choice but to comply. For in Wonderland, not sticking to the script can have deadly consequences

Musical instruments have minds and bodies, feelings and thoughts. When tossed aside and abandoned, they can become corrupted, even murderous. Petrushka is an instrument unlike the others; she can't make music at all. After she's found by the mysterious Rentarou in a trash heap, they must team up to calm a despairing lute and perhaps reveal the secret to Petrushka's lack of musical ability. Can Rentarou somehow unlock her latent talents? (Source: Fallen Syndicate)
