Vassal Musical Instrument

The Vassal Musical Instrument is one of the eight Vassal Weapons of Glass' World. The current candidate of the Vassal Instrument is Itsuki Kawasumi. He was selected by the Musical Instrument vassal wielder during the campaign of rescue Kizuna after defeating the illegitimate wielder, Miyaji.

Overview
The first known user of the Musical Instrument Vassal Weapon is the Vanguard of the Wave, Hidemasa Miyaji. This fake hero used the weapon to gain power within the Vassal Instrument country and to kidnap the Holy Hunting Hero, Kizuna. As a Vanguard of the Wave, he was not a worthy wielder of the weapon and had to suppress it using an accessory. However, the Vassal Musical Instrument was liberated from the suppression accessory and it chose Itsuki Kawasumi as its new successor.

The power-up method from the Vassal Musical Instrument is a version of status enhancement via cash. With this power-up, a Legendary or Vassal weapon could provide status upgrades for money such as +1 to magic, increased maturation rates or magic recovery speed.
