I am not trying to be the hero. I am not trying to become awesome and get all the fame, i just want to save her.

— Jens, Arc 1

Jens is the male protagonist in Re:Kingdom. He is a mysterious person that got summoned to Lugunica by Satella without any memories of his past. He soon met Emilia and became her knight and lived at Roswaal L Mathers's Mansion. After he saved the Mansion against eBranwen's Infilitration, Jens and Emilia started to date.

After the Witch Cult attacks in Nastra and Priestella, Emilia and her camp decided to save Arlam Village, where the Sanctuary was and where both Emilia and Jens completed Echidna's Trials. Thanks to the Trials, Jens learned how to use his Witch Abilities with full potential. During his second trial, Jens created a contract with the Artificial Spirit Beatrice, and she became his main source of Mana and the two became a strong duo. Later, Jens and his friends made their way to meet the Sage, however, the Sage was absent and the group met his apprentice, Shaula. They succeeded the Sage Trials and Jens officially became the Legendary Sage, gaining him his alias.

Five years following his death against Sirius A, he lived under the identity of Eos Auxesia, a Volakian Soldier which was the mentor of the Quinx Squad. His memories were initially lost to him, but regained during an Extermination Operation at the Sanctuary.


Jens is a man with light skin and is slightly below average height, with a lean and toned build. He has spiky blond hair and blue eyes. Jens wears a standard soldier uniform. This is the uniform he wears for most of his other appearances, with slight variations. He has a silver earring in his left ear.


Jens is a really nice guy. He never judges people on their look. Though Jens does hesitate sometimes if he can trust a person or not. Either way, he is always loyal to the person he loves or likes. Jens has always been nice, even after all the things he went through. While Jens tends to not read the situations he encounters, ultimately leading him to make irrational decisions, he is loyal to those he holds dear, willing to help them, even if that means taking the thorny path. He has his resolve confirmed through the many situations and circumstances he faces. Eventually, he resolves himself to be faithful and protective of the ones that he cares most about.


Black Aura: Jens has a somewhat rare aura color. Black is an Aura color which means death or the end.

Sword skills: Through all the years of training and fighting, Jens has considerable skills with a sword. Though all of his enemies would judge him by his look and consider Jens weak.

Legendary Legacy of Leo : It's rather unknown how he received the Legacy of Leo, however he does have access to all weapons which contain in the power. He's able to summon multiple weapons at the same out of thin air and it doesn't require mana.

  • Blade of Eldia :
  • The Spear of Vengeance :
  • Thas'Dorah, The Legacy of The Windrunners :
  • The Katana of Summer :
  • The Medallion of Summer :

Equipment: Jens had a lot of weapons before the Yetar. So he gets used to his weapon pretty quick. Though Jens prefers a sword rather than an ax. Currently, Jens wields a sword created with Magic which he calls the Dark Crusader.

Authority: Jens can use several Authorities after he killed a Sin Archbishop that represented that sin.

  • Authority of Wrath: Jens has the Authority of wrath after recruiting Sirius to join Jens' side, Sirius gave a half of his Witch Genes to Jens.
    • Soul Shackle: Jens can share or transmit their emotions and senses to others. After polarizing emotions such as anger or sorrow, Jens can transmit it to any people in their vicinity, either taking control of them or resonating a certain emotion between a certain amount of people to raise it to the point of madness. Also, since Jens can share senses such as distress or pain, if anyone dies within the affected area Jens can force others within the same area to die the same way.
  • Authority of Sloth: After killing Elza Kirite and Petelgeuse Romanee-Conti, Jens got the Authority of Sloth and has the full potential of Sloth.
    • Flux:Jens can let out a black wave toward their surroundings, corrupting the minds of those who have no knowledge of Spirit Magic. Those affected experience hallucinations, auditory hallucinations, and severe pain, then expose the whites of their eyes, foam at the mouth, and are nearly driven mad. The Magic, Blessings] and other powers are stolen and given to Jens.
    • Hand of Despair: Jens can cause physical interference by creating an invisible force field in the shape of a hand. The effect area, power, and number of hands are based on Jens, and according to Pack the Witch of Envy] was able to manifest 2000 hands at once.
  • Authority of Greed : Jens has the Authority of Greed after drinking Greed Tea at the Sanctuary, however, his Authority of Greed isn't complete as he hasn't Witch Genes itself, which belong to Regulus Corneas
    • Step through Time : Jens can stop the time of themselves or anything they're wearing, touched, or even their breath. This stops any interference from outside and only allows Jens' interference outwards. This negates any attack against Jens, and if Jens waves their hand, anything in its trajectory is cut no matter the toughness. Atmosphere released from the stillness can cause shock waves, gravel thrown around can become inevitable shots, and it can enable Jens to travel at extremely high speeds.
  • Authority of Gluttony: Jens has the Authority of Gluttony after killing both Roy Alphard and Ley Batenkaitos, however, his Authority of Gluttony is incomplete as he hasn't the 3rd Gluttony Witch Genes, which belong to Roy Alphard
    • Feast: Jens can eat the name and memories of their opponent. To eat a name, Jens touches them with their left hand, then licks the palm of the same hand. Things such as experience, talent, and the likes and dislikes of human relationships serve as food for Jens, allowing them to take advantage of any abilities or memories their opponents had. However, if Jens eats a fake name, they are plagued with severe nausea.
      • Those that have had their names eaten have their existences erased from the world, destroying any human relationships along with preventing the use of magic and negating any contracts with Spirits.
      • Those that have their memories eaten become amnesic and any characteristics they may have had are reset, effectively making them into a different person.
      • Those that have both their name and memories eaten simply become a shell, and although they live, they no longer eat, excrete waste, or age, putting them in suspended animation.
  • Authority of Pride : Jens has the Authority of Pride which he got from Satella and he calls the ability Return by Death
    • Return by Death is Jens' primary ability. He uses it to return by death every time he dies. He returns to a randomly picked point before he died.

Yin Magic: Jens is a nonskilled Yin mage. While his gate is half broken, his artificial spirit Beatrice helps him consuming Mana from her gate or from the atmosphere. He has several abilities he actually used by himself:

Spirit user: While Jens his gate is broken, he can still use Yin magic, because of his artificial spirit, Beatrice. Though according to her contract, he isn't an actual Spirit user, so he can’t use his maximum power in a real fight. The contract has some rules to make Beatrice his Artificial Spirit:

  • Jens cannot form a contract with other Spirits
  • Beatrice cannot restore mana on her own
  • Beatrice cannot use the mana in the atmosphere
  • Beatrice can only drain mana from Jens.


  • Jens’ surname is still, to this day, unknown.
  • His birthday is on the 28th of April.
