 is a weapon in SINoALICE.

Weapon Story
The honest demon had not forgotten the nun who rescued him when he teetered on the verge of death. Once he'd recovered, he gave her many gifts in return. However, he made a decision to spread rumors about why he was visiting her for his own sake.

The rumors claimed that the nun invited him. But demons are hated by humans. A fact that this particular demon could not comprehend. Of course, her love was unable to reach him.

There were rumors of a nun who was in love with a demon, making her the most desperate of star-crossed lovers. She had become smitten by the sight of his black wings. Though the thought of him was all consuming, her love went unrequited.

Play this instrument to let me know when you're about to die." That was the last letter the demon left her. Time passed, and the nun was on her deathbed. Before an angel could visit, she played the demon flute as promised and was delivered to hell.
