An officer of the 21st Airborne Unit of the Orb Union's ground forces. Kisaka was born in the town of Tassil in northern Africa, though his family is no longer there. When Cagalli travels to North Africa to fight alongside the Desert Dawn resistance group, Kisaka accompanies her as a bodyguard though the Desert Dawn's leader, Sahib Ashman, was also aware of Cagalli's true identity. Ledonir join the Desert Dawn in helping the Archangel after it accidentally landed in ZAFT territory and was surrounded by the forces of the "Desert Tiger", Andrew Waltfeld. It is later revealed that Cagalli is acquainted with the GAT-X105 Strike Gundam's pilot, Kira Yamato.
In retaliation for Desert Dawn's attack, Waltfeld attacks the nearby town of Tassil, destroying all supplies and resources, but sparing its population from any harm. Although Mu La Flaga and Sahib are aware Waltfeld intentionally left the civilians unharmed as an act of grace, the enraged members of the Desert Dawn launch a foolhardy attack against Waltfeld's superior TMF/A-802 BuCUEs. Ledonir rides in the same jeep as Cagalli and Ahmed el Hosn as they fire rockets that only succeed in disrupting the BuCUEs' cameras as the BuCUEs attack and kill several resistance fighters. One of the BuCUEs notices Cagalli's jeep, and Ledonir realizes this and grabs Cagalli before jumping off. Ahmed was mortally wounded by the attack, and only the timely arrival of Kira in the Strike was the ZAFT forces forced back.
To gather supplies, the group later headed to a nearby city, which also hosted Waltfeld's HQ. Sahib, Natarle Badgiruel and Ledonir then split from Cagalli and Kira to negotiate a purchase of military supplies and water. After successfully securing a deal, Ledonir is unable to find the Cagalli and Kira and reports it to the Archangel. He also told them about reports of Blue Cosmos terrorist attack in the city. Following Cagalli and Kira's return, the resistance accompany the Archangel in engaging Waltfeld's ship, the Lesseps. Ledonir was at Cagalli's side as she was determined to avenge Ahmed's death. Although the pair were nearly crushed, the battle ends in their favor as Kira successfully destroys Waltfeld's TMF/A-803 LaGOWE, while the Lesseps was severely damaged by the Archangel.
Once the two groups reach the Indian Ocean, Ledonir and Cagalli opt to join the Archangel, while the Desert Dawn returns to Africa to continue their resistance. Ledonir advises captain Murrue Ramius to avoid fighting as although the Alliance's higher-ups ordered the ship to head for Alaska, they offered no support in terms of supplies or planning. However, it becomes apparent that the optimistic idea of evading battle will not work as the Archangel fends off attacks from Marco Morassim's forces and then an assault by a mobile suit team led by Athrun Zala. As the battle occurs close to Orb waters, both Cagalli and Ledonir urge Captain Ramius to enter Orb territory in spite of its coast guard's warnings. Due to the damage that the ship sustained, Ramius has little choice and complies. Upon docking at a secret port, Ledonir reveals his true identity and that of Cagalli's.
Ledonir later reports the combat record of the Strike and the skill of its pilot to Erica Simmons as she needed more data to complete the MBF-M1 M1 Astray. When the Archangel is ready to depart, Ledonir makes a parting visit where he reviews the Archangel's route to Alaska and confirms that they did not sight any ZAFT ships nearby. He does inform the crew, however, that it would only be hopeful thinking that the ZAFT forces were gone as it took extensive negotiations to convince them to leave. When Lieutenant Badgiruel inquires about the truth behind the mobile suits made in Heliopolis, Kisaka replies that several cabinet members had acted independently and yielded to pressure from the Atlantic Federation. Kisaka also points out that the last thing Uzumi wanted was his people to suffer, thus his reluctance in getting Orb involved in the war. Both parties then exchange thanks and Kisaka left the ship.
Not long after, the coast guard reported a battle between ZAFT forces and the Archangel at a nearby island. Kisaka accompanies Cagalli to an island where the investigation team finds the wreckage of the Strike and the GAT-X303 Aegis Gundam. While Kira is nowhere to be found, the team finds an unconscious Athrun Zala, the Aegis's pilot, washed ashore. Ledonir then help with the salvage work as Cagalli interrogates Athrun. Following the battle of JOSH-A, the Archangel and its crew decided to break away from the Alliance and headed to Orb for sanctuary as well as to report the growing radicalism of the Atlantic Federation. Later, the Alliance lost its Panama Mass Driver to ZAFT, causing its leaders to deliver an ultimatum to Orb: Join the Alliance or be treated as ZAFT sympathizers and enemies.
Knowing these terms to be intentionally unacceptable, Uzumi rallies his military and evacuates civilians. Kisaka then aid Cagalli in overseeing the battle of Onogoro. Despite Orb's technological superiority, the Alliance's greater numbers and relentless attacks prove too much for the defenders, and Uzumi, knowing the country was doomed, hands Cagalli to Kisaka and orders them to board the Kusanagi and flee to space.
In space, Kisaka act as the Kusanagi's captain and had the ship provide support to the allied Archangel and later, the FFMH-Y101 Eternal in several battles. During one such battle at the Mendel Colony, the Kusanagi and Eternal successfully sink Rau Le Creuset's flagship, Vesalius, creating an opportunity for the three allied ships to escape. Kisaka also command the ship in the final battle at Jachin Due as Cagalli had left to join the fighting. After the war, Kisaka returned to Orb's ground forces.
Gundam SEED Destiny
During the Second Alliance-PLANT War, Kisaka is seen in an Earth Alliance uniform working under disguise. By coincidence, he spots the battle between ZAFT's ZGMF-X42S Destiny Gundam and ZGMF-X666S Legend Gundam against a lone ZGMF-2000 GOUF Ignited. Noticing the GOUF was shot down, Kisaka quickly reaches the crash site and rescues Athrun Zala and Meyrin Hawke before handing them to the Archangel for medical treatment. He later pilots Waltfeld's custom MVF-M11C Murasame during ZAFT's invasion of Orb, and remains behind in Orb with Cagalli after the Archangel heads to space.
