Flute of Excess

 is a weapon in SINoALICE.

Weapon Story
A boy picked up the flute by the river, but quickly went into a daze as if possessed. His parents couldn't understand why he would play horribly out of tune well into the night.

He suddenly showed rapid improvement and earned the respect of a great musician. After that, his parents lauded him as a genius.

Though the boy was pure, he desperately craved praise. He continued to play the flute and asked of his listeners, "Hey! That was good, right? See how much better I've gotten?"

The talent to make such beautiful music came at a price. The flute was fueled with the wailing cries of those who were about to die. The boy killed many people, all for the sake of greater praise. More and more and more more more—there was no limit to the slaughter.
