Jidan Guisu is a minor antagonist in Suikoden V.
During the Sun Rune War, he had made an agreement with Salum Barows to capture and assault General Novum's forces. The purpose of this is to make Prince Freyjadour Falenas indebted to Armes and grant Salum Barows to develop power. But, Georg Prime discover their plot and Lucretia Merces planned to counter it, Dilber Novum's forces and Freyjadour's forces formed a temporary trust and attack Jidan's forces. Jidan's forces withdrew.
Jidan came to Lymsleia's coronation ceremony as a guest, there Marscal Godwin offer, that if the Loyalist Army is destroyed, they will gave all the Barows State to Armes, Jidan and Maha Sparna agreed to it and started to help the Godwins.
Jidan's first attempt to help the Godwins is to capture Sable, his second attempt is to take Lordlake but Lucretia predicted this to happened so she advice Freyjadour to warn and evacuate the people of Lordlake and Sable before Armes forces came.
The Arme's forces had successfully take the Loyalist Army's headquarters, the Ceras Lake Castle, but the Loyalist Army allied themselves to the Dragon Cavalry and retake their headquarters back. The Arme's forces ran and retreated back to Sable.
Unluckily the Loyalist Army arrive quickly, before they move all their forces out of Sable. Maha Sparna decide to fled in fear and block the gate to Armes leaving Jidan behind so that the Loyalist Army could not follow them.
Jidan with no where to go decided to assault the Loyalist Army but defeated by General Dinn and the Loyalist Army. In the end he was killed.
