Potimas Harrifenas is the elf patriarch and ambassador of the Elf Village.

Potimas is known for being extremely cunning and a brilliant inventor, due to his selfish pursuit and actions that constantly push the world into destruction, he is considered one of the main antagonist of the series. Using his extensive networks of spies, connections, magical gadgets and a league of followers makes him a troublesome foe to deal with.

The Creator of all Machines


Potimas appears as a standard fantasy elf, he has blue eyes and a long blond hair tied as a ponytail.


Come, then, you foolish girl who drew the unfortunate lot of Demon Lord. Perhaps death will prove to you that you were mistaken in assuming that someone who can only watch in silence as everything they have rots away would be able to challenge the likes of me.

— Potimas Harrifenas

He is a control freak and a narcissist, absolutely obsessed with obtaining Immortality. This obsession has driven all of his actions since before he was 10 years old. It is this diligence towards this goal that earned him the skill Diligence and the title Ruler of Diligence[1], but also twisted him into a sociopath. He cares not for the living creatures he creates, always throwing them away if he no longer has a use for them or if they become a burden to him.

As noted by Ariel, due to his vindictiveness', stubbornness and immense selfishness, Potimas's overall mentality itself was comparable to a spoiled child that never grew up. An assessment that was confirmed by both Shiraori and Güliedistodiez.


Past Arc
From the moment he was first aware, Potimas has been terrified of death. In ancient times, he is a world-famous researcher who got involved in every field of science in his search for a means for survival. Sensing the limits of conventional science, he seeks to understand the magecraft by which the dragons of the world performed supernatural feats.[2]

To do this, he induces a criminal organisation to abduct an infant dragon. From the few tests that were able to be done before the infant was rescued, he was able to conclude that there must be rules behind the action of magecraft. After years of diligent research, he discovered a technique for drawing the world's MA Energy.[3]

Using MA Energy, Potimas creates vampires, rogue forms of creatures modified through a type of magecraft, which had been hunted into extinction by the dragons and Sariel. While the vampires are immortal, they also lose their sanity, so Potimas doesn't choose to apply the procedure to himself. While searching for a way to preserve the sense of self, his institute was exposed, forcing him to flee and causing a vampire outbreak.[4]

He releases his MA-drawing technique to the world, claiming that it is an unlimited source of energy, as well as the fruits of his research into vampirism and chimera, a technique that extends a human's life expectancy by threefold. Despite being a wanted criminal, MA Energy and evolution became widely used.[5] He also disseminates designs for anti-god weapons to many of the world's militaries.

While pressured by the ongoing eradication of humanity by dragons, Potimas succeeds in evolving himself into an immortal race that is later known as elves.[6]

After the dragons take most of the remaining MA Energy in their departure, Potimas intends to escape the dying planet. Knowing that he would struggle to survive off planet, he devises a plan to decompose Sariel and reform her energy into a weapon design that would come to be called Gloria Ω.[7] However, the moment Sariel steps into the decomposition equipment, Gyurie proclaims the beginning of the System.

Potimas first appeared along with his daughter Filimøs during a political meeting with the King of the Kingdom of Analeit. While he's at the castle he encountered Shun and Katia.

Potimas is the Ruler of Diligence, and has survived since before the System was put into operation. Being entirely focused on not wanting to die, he threw the world into a maelstrom of chaos. Both a genius and a natural calamity, he evolved himself into a new species known as the elves, and is continuing his research in order to achieve true perpetual youth and longevity. After the System was put into operation he was threatened by Gyurie to behave himself, and being frightened of that he shut himself inside the barrier. Even so, he got up to various things behind the scenes leading to the current situation.

Character File

The chief of the elves, he holds complete authority over his race. He is the father of Filimos, also known as Ms. Oka, a reincarnation. In accordance with her wishes, he sets out to gather the other reincarnations and protect them. This is not due to the goodness of his heart, however, but rather in accordance with his own motives. He thinks of all other elves as nothing more than pawns. Potimas is not simply their leader; in his mind, it is no exaggeration to say that the entire race of elves exists solely for him to use as he wishes. What he intends to do with them is known to no one but himself.


Potimas has a large number of cyborg clones made using a combination of science and magecraft.[8] A captured clone was found to have been made using magecraft to enhance its hardness and maneuvrability, in addition to some small prepared magecraft invocations. These abilities were probably developed using System Skills as the starting point, and would have defensive status values of approximately 10,000. The clone was found to be at least 800 years old.[9]

  • Elf Physiology: Elves have naturally a slow rate of ageing and a longer lifespan than most humanoid beings.
  • Master Engineer: It was shown in the Web Novel, he was able to create robots that were designed to fight with a god.
  • Bioengineering: In the past, it was revealed he conducted illegal genetic experiments on people using a new source of energy he discovered and experimented with animal DNA in order to create new hybrid beings to further his goal of learning the secrets of immortality. Potimas himself is the creator of the incredibly long lived Elf Race and was also the creator of Ariel, who in turn created the Spider Monster Race. It has also been implied that many of the other monster races within the World was also created both directly or indirectly by Potimas's creation.


  • The alias, "Eternal Child," is a moniker given to Potimas by Ariel and Okina Baba. Special chapters from his point of view give Potimas this title.
