Karchess Crim

Kachess Crim is a count and later king of the Kingdom of Marlon who had an affair with Queen Yufina Marlon. He is famous for assassinating Duke Sateriajis Venomania, bringing an end to the Venomania Event, and marrying into the Marlon Royal Family.

Venomania Event
At some point, Kachess met and entered an affair with Queen Yufina Marlon. Around EC 136, the count began investigating the disappearances of women across Asmodean, specifically those of Mikulia Greonio and Lukana Octo. While reading through a report in a local pub, he noticed Lilien Tarner's name on the list and began focusing on it.

Several months later, Kachess arrived at Earl Ferdinand's Mansion, greeted by the earl's uncle, to continue his investigation into the mysterious disappearances. Seated in the dining hall, the two discussed the visit of Lilien Tarner and the count learned that Duke Sateriajis Venomania had also been present at the time. He later came across Tarner's friend, Rajih, and offered him a chance to rescue Lilien from the Duke. When Rajih showed skepticism at the count's claims, he revealed he had obtained a key with the power to kill a demon.

After Yufina was enchanted by the Duke around EC 137, Crim managed to track her location and, disguised as a woman, approached the alleged demon. After Venomania embraced him, the count stabbed Sateriajis in the chest with the vessel of Wrath transformed into a Golden Knife, shedding his disguise as the Duke collapsed to the ground. Freeing the captured women, including his beloved, the Beelzenian Empire excused Kachess of his crime. The count later wedded Yufina and married into the Marlon Royal Family, becoming Marlon's king. At some point, he sired children with his wife, continuing the family legacy.

Legacy
Kachess would be remembered in history as the slayer of the "demon" Duke Venomania and freeing the abducted women from his captivity. Although having become part of Marlon royalty,  Crim's family line continued, with Joseph Crim, the chef of Banica Conchita, believed to be his distant descendant. Within the royal family, his descendant, Kyle Marlon, would adopt his name as a pen name and later use it as his alias during the Lucifenian Revolution.

Connections to Other Characters
Sateriajis Venomania: Although their meeting is brief, it's a violent encounter that leaves Venomania dead. When Kachess approaches him while disguised, he does not seem to expect anything, even calling him a beautiful woman. Venomania takes the newcomer into his arms, and Kachess uses this chance to stab him.

Yufina Marlon: Before her disappearance, she and Kachess were having an affair together. After she escaped from the mansion, the two eloped. Their grandchildren later become the rulers of Marlon, establishing their blood in the royal family.

Joseph Crim: A descendant of Kachess Crim. He became the chef of Banica Conchita and was killed by the woman's cannibalism.

Kyle Marlon: A descendant of Kachess. It seems Kyle is aware of this, as he has used the name of his possible ancestor in some occasions as pseudonym or nickname.

Rajih: Kachess offers him a chance to release Lilien from Venomania's grasp by using the Golden Key to defeat him.

Conceptualization and Origin
