Overview
The first known Vassal Whip wielder is Holn Anthreya - an alchemical research who lived in ancient times before the Bow and Shield world merged with the Sword and Shield world.

In the present day, the fist known wielder of the Vassal Whip is Takt Faubrey. He apparently was selected for the Vassal Whip after winning a martial arts tournament in Shieldfreeden. Whether he was legitimately selected or he used his weapon stealing ability is unknown. Eventually, Takt began his venture to take over Raphtalia's World. He killed as many Vassal Weapon wielders as he could find for their weapons and started to take over countries. Takt was eventually defeated by Naofumi who used his authority as a Holy Hero to strip Takt of his Vassal Weapons - including the Vassal Whip. The Vassal Whip flew away and the wielder is unknown.

The special ability of the Vassal Whip is to control the power of monsters.
