Harpoon Reincarnator

The Harpoon Reincarnator is one of the Reincarnated Individuals and Vanguards of the Waves who held the Vassal Harpoon and lead an enemy nation within Glass' World.

Appearance
The Harpoon Reincarnator is described to be a man with sharp eyes.

Personality
As someone hand-selected to be a vanguard of the waves, the Harpoon Reincarnator shares common characteristics with the other reincarnated individuals. He is in his own self-delusion where he is his own hero and the world is theirs to conquer. When he is winning, it is just natural "survival of the fittest" while if he is losing, the opponent must be cheating.

When a member of his party is injured, the Harpoon Reincarnator is willing to stray for the plan and rush towards the perpetrator for both revenge and attempt to repair the damage.

Abilities
The Harpoon Reincarnator wields the Vassal Harpoon, however he greatly relies on the weapon's skills instead of combat techniques. Therefore, opponents experienced in harpoon combat can easily read his attacks to dodge or counter. Despite his novice abilities, he was able to defeat a Legendary Hero summoned to Glass' World. He was given the Base Reinforcement ability as he was reincarnated but it never used to great effect.

Background
The Harpoon Reincarnator was an individual hand-selected by the organization behind the wave to be reincarnated based on his pliability and closed-mindedness. He was given the Vassal Harpoon which had an accessory to partially suppress its functioning as well as the Base Reinforcement ability. He eventually become a powerful leader within the Vassal Harpoon country and killed one of the summoned Legendary Heroes whom had thought they were in a game. During this time, he had also amassed both a harem for himself and a great army to take on the other heroes of that world.

Volume 19
After Miyaji was defeated, the Vassal Harpoon wielder was deemed to be the only major threat originating from Glass' World to the Heroes. He had apparently made plans with S'yne's Sister to join forces and attack the heroes. However, when the Demon Dragon Emperor had stripped Kuflika of her Demon Dragon power, the Harpoon Reincarnator was furious. Instead of attacking the heroes in one united front, he insisted that he brings a powerful group to assault the Demon Dragon. He brought himself, the Ofuda Reincarnator, S'yne's Sister, a false Demon Dragon Malty, and the Vassal Boat wielder.

During the attack, their attempts to strip Naofumi and his companions of their weapons failed and their nullification magic was reflected. The Harpoon Reincarnator faced off against Sadeena. Despite his superior weapon and stats, Sadeena was proficient with the harpoon and could read his every move. It was revealed that Rino had replaced the control accessory with breakable versions so Sadeena broke the accessory on the Vassal Harpoon. The Vassal Harpoon flew out of the reincarnator's hands to Sadeena. The former harpoon wielder attempted to get the Vassal Chain from S'yne's Sister but was promptly eaten by the Demon Dragon.

Allies

 * Kuflika: Kuflika was a monster who had gained the position of the Heavenly King of Wind. This position provided her power from the Demon Dragon Emperor in exchange for swearing loyalty. However, it turns out that when the Demon Dragon was resurrected, Kuflika had joined the Harpoon Reincarnator's group and refused the call of the Demon Dragon. As a result, the Demon Dragon stripped Kuflika of her Heavenly King power and status which left her nearly dead. Infuriated, the Harpoon Reincarnator strayed from previously arranged plans to attack the Demon Dragon.
 * S'yne's Sister: To the harpoon reincarnator, S'yne's Sister was offering her services as a powerful member under his control and as someone who could provide technology such as the false Demon Dragon. However, it turns out that the Harpoon Reincarnator was only a disposable part of the Third Army and was used by S'yne's Sister as a form of entertainment for the leaders of the organization.
 * Malty S Melromarc: The harpoon reincarnator was another vanguard of the wave who had been seduced by Malty. She was able to manipulate him as she pleased.

Enemies

 * Demon Dragon Emperor: After the Demon Dragon stripped Kuflika of her Heavenly King status, the harpoon reincarnator swore that he would get revenge on her behalf. The Harpoon reincarnator was enraged past reason towards the Demon Dragon but was eventually eaten by the Dragon after his defeat.
 * Sadeena: At first the Harpoon Reincarnator looked down on Sadeena since she didn't have a Vassal Weapon. However, she later proved herself to have superior skills and eventually defeated the enemy harpoon wielder - to his own disbelief. She received the Vassal Harpoon which he had thought was rightfully his.
