WN/Adalman

"My master (Rimuru)! Were you able to witness it? Our victory is for your sake!!"

- ‘Ghost King' Adalman

"Gehenna Lord" Adalman [ アダルマン,  Adaruman] is the guardian of the sixtieth floor in Ramiris’ Labyrinth. He made Rimuru his new "god", after being transformed into an Undead King. Albert is his confidant.

Personality
He is very proud and when he was defeated by Krishna, he refused to accept the opportunity to evolve into a demon lord.

He is also extremely loyal to Rimuru and wishes to become better and stronger for him.

He is extremely intelligent (ironically since he has no brain).

He is dedicated and kind, he trained Arnaud for several months just to help him.

Appearance
He has the appearance of a ghost and has no actual physical body. His appearance is made up of mere bones, which is quite pleasing to him. Though he is described as having meatless lips, so perhaps there is the appearance of some flesh.

Adalman while in a possessed body looks like a young man with black hair, clad in jet-black priest clothes. A younger version of he old self.

Background
In the past, they had gone to conduct a purification with good will to prevent the outbreak of a large-scale dead-spirits disaster in the battlefield in The Great Jura Forest.

In doing so, Priest Adalman and four holy knights had gone together, but they had encountered an unexpected situation.

When they had arrived at the battlefield's remains, a Zombie Dragon, an atrocious monster, was living there. Although they had succeeded in defeating the Zombie Dragon after a desperate fight, they had used up all of their strength.

There was no one to come rescue them, since they hadn't acted on the orders of the church, but based on their own convictions. Thus, their fate was sealed, but their hearts, which wished for the peace of the Great Jura Forest caused a miracle.

Adalman's group transformed into ghosts after receiving the curse of the dead, and a large amount of magic essence. However, with their strong willpower, Priest Adalman and Holy Knight Commander Albert succeeded in keeping their egos.

The Ghost King Adalman, who had acquired the abilities of a Necromancer, was dominating the dead spirits in the surroundings, and resided inside a cave.

That was an old story from more than several hundred years ago.

He once held the position of ‘great priest’, and had different position job before taking it. He was originally a high-ranking class of priest and martial artist known as the ‘Holy Fist Monk’. While he was an excellent vanguard he didn't need to perform close combat as he fought against the death dragon because he didn't think that it would be effective against her who had no physical form, so there were no opportunities to show those skills.

Story
He was assigned as a the guardian of the 60th floor.

He helped with the research and got along very well with the vampires and Ruminas. He was able to learn and improve the Day-Night Inversion. So, Ruminas taught him Holy-Demonic Inversion.

Albert defeated Arnaud during his and his holy knight's training run through the labyrinth. After Albert trained Arnaud for seveal months and his holy knights they were able to make it past the 60th floor.

Later they defeated Shinjy, Mark and Zhen even though they were high A rank adventurers.

After Rimuru learned of their improvement in their skills he moved them to the 70th floor.

He was defeated by Reiha and Krishna and thus did not feel worthy of receiving a gift of an evolution to Demon Lord. However he recieved the title of 'Gehenna Lord' instead.
