After Lukas was banished by Lord into the Abyss, the party disbanded and he eventually clashed with Lucid later on.

It was revealed later on that Kasajin died in the Amakan Desert after fighting a Demigod after a long period of time.

Kasajin was able to pass down his arts but it is limited to one master and apprentice per generation. He also passed down 3 relics that when gathered together, reveal an image of him demonstrating the Magic Warrior King Arts.

### Season 2

When Lukas was on Earth helping the humans fend off the demon invasion, he learned through a hint that someone from his world is on Earth. It was eventually revealed that it was Kasajin who was the Demon King and right-hand of the Black Horned Demon God. Kasajin gave the last name of his companions to each of this Grand Dukes as an ode to his past. He also skillfully carved images of his former party members and kept them in Demon territories.

On Earth, he commands all demons and is responsible for the invasion. He spends most of his time training and has advised his 5 Dukes to allow some time to train. He also taught the Magic Warrior's fist to his Dukes which explains why they can recognize or use the arts as well. He first makes an appearance when he left his palace in France after he completed his training to defeat the other Absolute residing in Europe, Sedi Glaston. She was coincidentally another subordinated of the Black Horned Demon God but lost quickly despite unleashing all her Absolute Powers. After defeating her, he took away her external force and her demonic energy demoting her to a mortal.

Kasajin first encountered Lukas again when he followed him to the Korean Hunter Branch in Busan. He immediately tried to kill Lucas by destroying the building. Even though he met Lukas again, he had no emotional attachments and had no qualms in fighting his former friend. He had remarked that even before, he won 9 times out of 10 when they dueled. He also declined to tell Lukas how he revived and became the Demon King. They continued to battle where he showed stances and moves that Lukas was unable to recognize. Kasajin's martial arts changed course from defeating Demigods to brutally killing opponents. He lost almost all his emotions after a long time being an Absolute but his thist for battle was reignited when he kept fighting Lukas. He stopped his battle with Lukas when they were summoned by the Rulers to commence the Great Game. It was revealed that Kasajin was sent to Earth to make it a suitable battlefield for the Great Game so that the tolerance of that universe would increase. His mission kept being delayed due to Lukas Trowman aiding the humans.

As the 0th demon, Kasajin ruled over all the demons in Demonsio, until Sedi Trowman came and took his position by defeating him in battle. He met with Lukas in demonsio and tried to warn him about Sedi Trowman using the power of the Demon King of Black Thorns.
