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

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

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

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.

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 ghost 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 stayed inside a cave.

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

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.

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'
