Clive

Clive, a young man of the upper aristocracy and a social knight, is the first leader of the Zofia libertation army, the Deliverance. He was originally the captain of the Order of the Zofia, but with the coup d’etat of chancellor Desaix, through suggestion of his lover Mathilda, they founded the Deliverance, along with Fernand.

Being harassed by Desaix's forces, Clive and the Deliverance were forced to take refuge in a cursed graveyard, making the haunted grounds a makeshift headquarters. His bride Mathilda and his younger sister Clair were kidnapped during one of the battles, and the failed attempts to rescue Mathilda let him shaken and doubting his own leadership qualities, resulting of the whole army being also down.

When Alm and his group arrive at the Deliverance Hideout, Clive heartily greets them, grateful to them for rescuing his sister. Clive was disappointed that Mycen would not join the rebellion, but decides that, with the increasing number of commoners joining the Deliverance, he should cede the Deliverance's leadership to Alm, the grandson of the legendary knight Mycen, as he believes that Mycen's story of rising above his common birth to become a knight and count of Zofia resonates with the commoners, and Mycen's grandson would be better suited to lead them. Fernand is outraged by this, and abandons the Deliverance on the spot, rather than allow himself to be led by a common villager such as Alm.
