Vassal Gauntlet

The Vassal Gauntlet or Seven Star Gauntlet, also known as the Gauntlet Spirit of the Vassal Weapon. The spirit is from another world prior to being summoned to another world, the Vassal Gauntlet is one of the eight Vassal Weapons present in the world which Naofumi currently resides in. The candidates of the weapon have been given the title of Gauntlet Hero, whom they are generally addressed as so by the locals. The current candidate of the Vassal Gauntlet is Fohl Fayon.

Overview
The Vassal Gauntlet was first seen inactive in a country in the west where the Phoenix was sealed. Apparently, the previous hero which had sealed the Phoenix was a gauntlet hero. At the time Naofumi and his party arrived to fight the Phoenix, there was a large line of people trying to test if they were "worthy" of wielding the gauntlets but no one was able to lift them.

During the fight with the Phoenix, Atla was killed due to Takt's interference. As her brother Fohl grieved, the Vassal Gauntlets flew to him and chose him as their new wielder. At first, the Vassal Gauntlet's power-up method were blocked by the "world destroyer" behind the waves but the spirit of the Legendary Shield unlocked them. During the fight with Takt, the Vassal Gauntlets were briefly stolen but were quickly returned as Naofumi used his authority as a Holy Hero to released all of the Vassal Weapons to their legitimate wielders.

Power-up method
The power-up method for the Vassal Gauntlets is "Skill Power-up Points." This power-up method provides points to heroes as they level-up to enhance their skills. This heroes can redistribute these points at will. Sharing this power-up method is only effective if the heroes work together.
