Wolf Shamisen

Weapon created from Yian Garuga tail. The 3 strings twang in nostalgic tones.
A weapon that takes the shape of Yian Garuga's tail and turns it straight into a hunting horn. When the makers recreated a three-stringed instrument said to have been played in the East since ancient times, it proved a perfect match for Yian Garuga materials and gave out a tone both beautiful and fleeting.
