Run

Run was a member of the Jaegers, who now serves as one of Kurome's puppets. While alive, he was arguably the most mysterious member of the Jaegers.

Appearance
Run was a young man with fair blond hair and golden eyes. He wore a white robe on top of a black shirt and pants with a brown belt, a feather pin behind his ear and a collar-like accessory on his neck.

He was also shown to have a winter outfit with a white jacket and a scarf, he also wore formal suits on several occasions.

Personality
Run was calm, collective, and polite. He had never been shown to raise his voice or give in to anger, and was determined to make his goals a reality. He was not above using dishonorable methods to reach his goals, such as seducing women and deceiving his enemies to gain their trust; as seen when he was pretending to try to get into Wild Hunt by being nice to its members while in truth, he was gathering incriminating evidence against them.

Run was willing to defend civilians, and clearly detested Wild Hunt, hiding his anger regarding the public execution of the Imperial Fist disciples. He also was very caring to his fellow Jaegers, and was present during the mourning of his fallen comrades. He grew especially close to Wave and Kurome, and was willing to risk his life to protect them.

History
Some time before the starts of the series, Run was a school teacher in a peaceful town near Joyou. One day he returned from an errand to find all of his students brutally slaughtered.

However, because the town wanted to keep its reputation intact, it covered up the incident rather than investigating it. Seeing this as a problem in the Empire, Run worked his way up the military (via seducing the town's mayor) in order to start changing it, as well as to find the culprit behind the slaughter.

After his introduction as part of the Jaegers he soon began serving as Esdeath's personal aide. He located Dr. Stylish's secret lab under Esdeath's orders. Some time later, when the Jaegers received a report of Night Raid making a move, Run was teamed up with Esdeath and Seryu, and accompanied her on their mission to attack Najenda, who was later revealed to be a decoy.

He was later seen in the next confrontation between the two parties, attacking Mine, Akame and Lubbock's Air Manta, shooting the group down. Shortly after the mission, he and Wave visited Bols' grave to talk to his family. When they returned to the capital, they witnessed the mangled bodies of the Imperial Fist disciples, killed by Wild Hunt. Despite Wave's rage and his own inner anger, Run held Wave back, warning him that Syura was the Prime Minister's son.

After Wave recovered from his victory against Syura in a one-on-one fist fight, Run told them about his goal to change the Empire from the inside and about his past. That night, Kurome intercepted him on his way to the Wild Hunt HQ, revealing that she was aware from the conversation that the culprit behind the slaughter was in Wild Hunt. Agreeing that the group brought no benefit to the Empire, they decided to work together to destroy it.

Run lured Champ out of the base as Kurome prevented Cosmina and Enshin from intervening. Run, with the help of Natala and Doya, managed to pierce Champ with multiple feathers including one in his eye and proceeded to brutally torture him, leaving him to die. He then rushed to the aid of Kurome who got cornered by Enshin and Cosmina; however, both got trapped in a whirlwind caused by Champ's elemental Teigu, and Run sustained a lot of damage protecting Kurome during a fire explosion. Champ used one of his orbs to try and kill Run, who deflected it with his trump card, redirecting the orb back at Champ, killing him.

When Night Raid arrived on the scene to fight Wild Hunt members, Run carried Kurome to safety with his remaining strength; as he accepted his imminent death with a smile, a mentally unstable Kurome rejected the thought of her comrade dying. She stabbed Run with her Teigu, killing and reanimating him as a corpse puppet. In his final thoughts, Run questioned the extent of Kurome's psyche being warped and once again lamented the corrupted state of The Empire.

Despite being turned into a mindless puppet, Run still holds his strong habits and desires, able to intervene between Kurome and Wave's dispute that he should rest in peace and showing his yearn to care. It was also revealed that Run successfully investigated on the Danger Beast incident caused by Syura which was used by Esdeath to disband Wild Hunt.

Equipment & Skills
Run's Teigu is called "Soaring for Thousands of Miles: Mastema". Its basic skill gives Run a pair of wings that allow him to fly and unleash piercing feathers to strike foes. It also has a trump card, which allows him to reflect attacks.

He is shown to very fast, being able to keep pace with Esdeath's initial attacks when she comes to test the Jaegers. He was intelligent and capable of deductive reasoning on par with Esdeath; he also proved to be skilled in infiltration and intelligence gathering, as well as investigating crimes.

Trivia

 * Mastema is the name of a fallen angel or a demon in Jewish mythology. His character is a personification of the Hebrew word, "mastemah" (משטמה), which can mean "hatred", "hostility", "enmity" or "persecution", and was portrayed as a warrior angel of destruction leading his own army, or as an agent of God that punished evil. This could be a reference to Run's character, as he was a merciless killer despite his angelic appearance and fought against evil both on the Empire's behalf and with his own motivations.
 * Run had a habit of rubbing his chin whenever he was in deep thought or analyzing the situation.
