Harpy's Harp

 is a weapon in SINoALICE.

Weapon Story
There once was a strange bird that captivated the king with its beautiful voice.

"That bird would make a wonderful harp," the king thought.

The next morning, he promised a huge sum of money to a pair of blacksmith brothers in exchange for the instrument.

The older brother was lazy, but the younger was diligent.

Despite this difference, they were as close as could be. The promise of a huge reward, however, was more than enough to create a rift between them, and the younger brother finished the task as the older slept.

The younger brother proudly displayed the bird's corpse.

Without a moment's thought, the older brother, blinded by greed, thrust a kitchen knife into his younger brother. To hide his guilt, the older brother blamed the younger's death on the bird and left to see the king.

The harp was eventually finished, and the king was eager to hear it.

The harp began to sing.

"The elder brother's heart is coarse, he killed the younger without remorse."

The king understood and had the older brother beheaded.
