Ratten's Flute

The rat catcher's flute is a Gift first introduced in Volume 2 of the light novel during the attack on Salamandra. It is described as a "wind-cutting flute." Later, it is shown to be used by Asuka along with her two other gifts, Deen and Amalthea when Azi Dahaka awakens.

Description
Ex-Owner : Ratten

Current Owner : Asuka Kudou

A wind-cutting flute that once belonged to a kidnapping demon, Ratten, affiliated with Grim Grimoire; Hamelin that Jack later customized for Asuka.

Abilities
Under Ratten, it was a Gift that controlled the hearts of both humans and beasts alike with its sound.

After Ratten was defeated, it was changed by Jack into a Gift that "by the sound of cutting the wind, told the words of its wielder to others" which would, under someone other than Asuka, be a simple tool of communication. However, under Asuka, coupled with her Gift that gave Divinity to others with her words, the effects were much greater. When coupled with Amalthea and her other Gifts, it is called "Shrine Craft ."
