Vassal Scythe

The Vassal Scythe is one of the eight Vassal Weapons from Glass' World. The person who possesses the weapon is called the Scythe Hero. The current Scythe Hero is L'Arc Berg Sickle.

Overview
The Vassal Scythe was first seen in the possession of L'Arc Berg Sickle who is a king and Vassal Hero of his world. He has apparently had the Vassal Scythe for a relatively long time.

While the Legendary Hunting Tool hero Kizuna went around their world trying to unite the countries against the waves, a reincarnated individual they thought was an ally attacked them. Kizuna was kidnapped and L'Arc had his scythe stolen using the same accessory technology as Takt. The vanguard of the waves which stole the Vassal Scythe then attack L'Arc's country. Thanks to Naofumi's timely arrival they were able to liberate the Vassal Scythe and it returned to L'Arc.

Power-up Method
The power-up method for the Vassal Scythe is "Spirit Enchant" which is similar to the Legendary Spear's power-up method. This power-up method absorbs the souls of enemies which can be used to imbue special powers onto the weapon.
