Xylophone Arles: Scream & Rhythm.

Arles Rose is a young man who has perfected the art of the "Pretty Demon"...masking a cold, calculating mind and a talent for violence behind a face of curated beauty. In the grey, gossip-fueled city of Cameo Orchards, Arles and his tight-knit circle of social outcasts navigate a senior year defined more by blood and reputation than academics. While Arles waits for a sign of affection from his disinterested, honeymooning mother, he occupies his time protecting his friends: the kind-hearted Gail, the cynical Mitsuya, and the hot-headed Red.
In this city, justice isn't found in a courtroom, but in the parking lot of Maggie's Harbour Cafe, where Arles settles disputes through lethal, antique-gun duels. However, the group's "questionable reputation" eventually draws the attention of a beast far more dangerous than any high school bully. When a predatory doctor enters the fray, Arles is thrust into a nightmare of abduction and betrayal that tests the limits of his friends' loyalty.
