Kazuki

In the country of the Sword Vassal Weapon, there was a man known as a genius mage. His personality was selfish, and Naofumi Iwatani nicknamed him "Scumbag No. 2." He possessed unusual talent and was able to replicate the transfer skill from Kizuna Kazayama's world, firing off various elemental magic spells without incantation. However, none of his magic was effective against Naofumi Iwatani.

When he attempted to replicate this in the country of the Mirror Vassal Weapon, he encountered Naofumi Iwatani and his companions, tried to capture them, but they managed to escape. Later, he challenged the selection ceremony for the Sword Vassal Weapon. When Raphtalia was chosen as the wielder, he attempted to steal her away but failed and was defeated by her. While pursuing him as he tried to flee, his wounds reopened and he lost his life.

After his death, he tried to transfer his soul into a spare homunculus, but his soul was consumed by Kyo Ethnina. As a result, both his corpse and the homunculus were manipulated by Kyo, and were ultimately incinerated by Glass and Therese Alexanderite. His actions to seize Vassal Weapons from others raised suspicions, but it was later revealed that he was a reincarnator capable of stealing weapons.
