Gradim Nava

Carrion's half-brother who fled the Beast Kingdom after failing to rebel against his father and brother centuries ago. He is the leader of the Demon Beast Corps and uses Beast Fusion.

Gradim is known as **Beast King** (魔獣王デモン・ビースト・キング).

## Story

***Empire's Invasion Arc***
Having witnessed the numbers and rank of the demons which Rimuru Tempest summons to battle the Empire's forces Beast King Gradim issued the Secret Command giving his subordinates permission to use the Medical Skill Beast Fusion.

Like Gradim, there were corps members who successfully fused and completed the process. These members consequently attained new powers and became stronger. These perfectly compatible individuals made up less than 1% among the entire corps. They were called Chimera Knights and were the aides of Beast King Gradim.

The order that Gradim issued, was akin to a death sentence for the Beast Corps troops. If there were unable to attain power now, they will simply end up as fodder for the demons. It was a cold, but pragmatic order. And the troops swiftly followed it.

They had prior knowledge to the risks of using Medical Skill Beast Fusion and knew of the high mortality rate. But because they had absolute faith in Beast King Gradim, they followed the order without hesitation.

## Abilities

### Skills

**Starving Ones:** This skill, bestowed upon Harkon's subordinates, allows them to eat anything and everything in sight. One of the effects of the unique skill known as Starved.

Although they could not obtain all the abilities of those that ate, they could still acquire some of their special features.

* **Provide**: Harkon gains the ability to obtain Skills from monsters linked to his soul. The original owner of the provided Skill will not lose the Skill because of this.

		- In a moving world, where there are many phenomenon in motion, the user's will influences all outcomes, but is not absolute.

**Medical Skill Beast Fusion**: This skill fused the Magic Beast and it's handler together. Letting a human attain the power of a Demon Beast; a forbidden power. The reason it was called a forbidden skill, was because it became impossible for the individual who activated it to cancel the effects. The drug used for the skill had to be surgically removed in a facility with the appropriate tools. Through the fusion of the handler and his partner, a warrior that surpassed the original concept would be born.

Of the 30,000 members of the Magic Beast Corps that use Medical Skill Beast Fusion:

* 7,750 turned into complete Demon Beasts. They became as if one being, able to move quickly on all fours and get a boost of strength.
* 4,000 into berserk Lycanthropes.
* 2,300 turned into Demonic-Beastmen. They displayed the ability to transform themselves into a more beastly form.
* 1,000 into Beast-Man Sages.
* 450 turned into Chimera Knights. The Chimera Knights obtained the Unique skill Bodily Manipulation.

It resulted in a fairly large loss in numbers.

* 15,500 of the original 30,000 troops lived. Of them only 3,750 retained coherent thought, and 1,450 of them retained their humanity.

However, there were corps members who successfully fused and completed the process. These members consequently attained new powers and became stronger. These perfectly compatible individuals made up less than 1% among the entire corps. They were called Chimera Knights and were the direct subordinates of Beast King Gradim.

## Relationships

The Magic Beast Corps handled various captured magic beasts: they breed, strengthened, and trained them. The cultivation of the Magic Beasts was processed through DNA analysis, the technology of the Other World that allowed the strong soldiers of the Empire to ride these beasts.

Those strong soldiers were said to have the blood of heroes who played an active part during the early days of the Empire in the times of old. Different from the Magic Remodeling technique that changes an ability-less person into a hero, they are born heroes having an overwhelming ability. A minor Corps with only 30,000 personnel. It was said that each one of them had the strength of 10,000 people while the Magic Beasts that they rode all had strength appropriate to A-Rank.

Medical Skill『Beast Fusion』was a skill that was developed by the team responsible for the analysis of Demon Beast DNA. The drug was distributed and kept on hand, so it was possible to activate it whenever necessary. But, usage is prohibited without the Secret Command from the corps leader (Gradim).

* **Battle Chimera**: The Chimera Knights handled various Demon Beasts; they breed, strengthened, and trained them.
* **Demon Beasts**: which were born from less compatible Magic Beast Corps soldiers, were seen as a type of weapon, having combat-oriented abilities.
