Veldora Tempest

Veldora LN

Full Name: Veldora Tempers
Date of Birth: Unknown
Age: 2000+
Height: 210 centimeters (Human Form) / 100 meters (Dragon Form)

Skills: Veldora Tempest is a catastrophe-class individual, considered by most human peoples to be a natural phenomenon rather than an individual. This is to the point that most of those affected, as well as most outside observers, view any damage Veldora causes as simple misfortune, rather than resenting it.

As such, he is also the strongest member of the Jura Tempest Federation, and though his title as Guardian Deity of Tempest is only a formality, his Divine Protection Storm Crest is applied to Rimuru and all those Rimuru has named, and during the naming process, some of his Magicules were also used

Since Rimuru possesses the ultimate ability Veldora, the danger of losing one’s ego upon death and resurrection characteristic of most spiritual lifeforms does not exist for Veldora either, as long as Rimuru and the ability are intact.

In human form, Veldora can use his self-developed “Veldora Killing Arts” for hand-to-hand combat. Veldora was somehow able to take the unrealistic and impractical fighting techniques from the fighting manga Veldora read from Rimuru’s memories and turn them into these practical fighting techniques that can be used for actual combat.

Benimaru is a highly skilled swordsman who can hold his own in a duel or a group in combat.

Shion Kijin Anime 1

Full Name: Shion
Date of Birth: Unknown
Age: Unknown
Height: 170 cm (Kijin) / 180 cm (Ogre)

Powers and abilities: Shion is an S-rank disaster class, comparable to unawakened demon lords. Shion is a skillful swordsman and can stand up to a sword duel or a massive battle. After being nominated by Rimuru and constantly training with her master to maintain or improve her skills, she continued to improve her skills with a blade.

She carries the Hercules Edge – Revised, an Ōdachi forged by Kurobe. Shion can easily hold it with one hand. Every time she swings the sword, a purple bolt of lightning passes through her, slashing and mowing down anyone in her path. The range of the strike is about 10 meters, an attack that kills everyone in a straight line. The scabbard is made of magical energy and disappears when Shion wishes it to.

Rimuru has reworked Hercules’ Edge, using Dead End Rainbow as a reference. This makes it a Soul Eater type weapon, even though he removed the seven strike function. Contrary to what the term “soul eater” suggests, the weapon cannot eat, damage, or otherwise directly interact with souls. It does, however, damage the spiritual body of those it hits, while also inflicting damage on the material body. Consequently, it inflicts both physical and spiritual damage, making it a dangerous weapon for spiritual and physical beings alike.

Unique and Extra Skills:

  • Battle Goddess
  • Chaotic fate
  • Spiritual being incarnation
  • Cook
  • Certain Outcome
  • Optimal Action
  • Ultraspeed Regeneration
  • Perfect Memory

Height: 155 cm

Powers and abilities: Unlike most other Oni, Shuna is only at Rank A, but is much stronger than her Magicule capacity would suggest, thanks to her effective and efficient use of magic and skills. Her ability to manipulate the law, in particular, makes her a dangerous opponent.

Full Name: Kurobe
Date of Birth: Unknown
Age: Unknown
Height: 180 cm

Powers and abilities: Not much is known about Kurobe’s fighting abilities. He uses a large hammer as a weapon, but since evolving from ogre to kijin, he has not had the opportunity to participate in combat. But as a craftsman, especially when it comes to swords, there is hardly anyone who can hold a candle to him.

Hakurou Kijin Anime 1

Full Name: Hakurō
Date of Birth: Unknwon
Age: 300+
Height: 157 cm

Powers and abilities: Although Hakurou was nameless, he never ventured out into the world and quietly honed his sword skills. He became the strongest swordsman in the royal guard of the ogre tribe. He even surpassed the head of the tribe, despite being a half-breed.

Hakurou is a master swordsman. He has impeccable strength. He is able to conceal his presence and body temperature. His perceptive ability is accelerated a thousandfold by the mind acceleration he received from Rimuru when he was named.

Hakurou was given the title of instructor by Rimuru. Magical energy escaped from Hakurou’s body, mixed with that of his surroundings, and then recomposed. The amount of energy in his body did not change. However, its quality did. The middle-aged kijin was invigorated and looked like he was in the prime of his life.

He uses his sword technique to overpower his opponent, not his physical abilities. This is remarkable because while he is only rated as A-rank according to the usual monster rating criterion of magic capacity, his mastery of the sword and training in various arts allows him to reach a special A-rank as it normally applies to humans.

When he fights the demon lord Milim, not even his attacks reach them. But he can fight back, which is impressive in itself.

Hinata Sakaguchi

Hinata Anime1OP

Full Name: Hinata Sakaguchi
Date of Birth: Unknown
Age: 25+
Height: Unknown

Powers and abilities: In her base state as a Saint in Transition, Hinata is already stronger than any average Demon Lord Seed. However, after equipping the Holy Weapons, she temporarily transforms into a full-fledged Saint and becomes strong enough to take on even an actual Demon Lord for a limited time. She is the physically/magically strongest person in the entire Church, with the exception of the Demon Lord Luminous Valentine himself, by whom Hinata was defeated.


  • Usurper/Surpasser (Absorbed by Chloe Aubert into Yog-Sothoth)
  • Usurpation – Seizes a target upon completion, allowing the user full control over it. Can be activated on any skills or arts that Hinata can see. The skill only works on beings of equal strength or stronger than Hinata, and when used it will either “Fail” or “Succeed”. If the being is weaker than Hinata, the result will show “Not Applicable”. The stronger the target is the harder it becomes to seize. There is no actual limit to the amount of attempts made on any single target, so even if the skill fails, she can just try again.
  • Seize- Takes away her opponent’s skills.
  • Copy- Learns the skills herself.
  • Mathematician/Unchanging One
  • Analyze & Assess
  • Thought Acceleration- Able to speed up the user’s thought process almost to where the world seems frozen in time. Hinata managed to rev her thought process by a thousand times while fighting Rimuru during the paladin’s attack.
  • Compute Prediction- Predicts the opponents attack and makes a visual path in the user’s mind.
