1,840 Years Ago

When she first appeared, she disguised herself as a male soldier from Marley and, under false orders from Magath, summoned Zeke, Porco, and Pieck. She deliberately separated Zeke from the other two. Because her disguise was not very natural, and Pieck had seen her before, he became suspicious of Pieck. During Liberio's operation, she was originally tasked with preventing Porco and Pieck from participating in the battle by trapping them in a pit specifically used to imprison Titans. However, due to Pieck's suspicion and their encounter with Tank Squad on the way, she was rescued by the Tank Squad, who were acting on Pieck's orders. This failed, resulting in greater casualties for the Survey Corps than expected.

Chapter 106 mentions that he and Onyankopon were ordered by Zeke to contact Paradis Island and Eren, intending to cooperate in liberating the Eldians. They also assisted the Survey Corps in learning new technologies and captured/eliminated the subsequent Marley reconnaissance fleet.

She was imprisoned and monitored in the villa by the garrison, Doto Pisis often went to talk to her.

In his conversation with Hange, Onyankopon mentioned that Yelena is a person who uses high-pressure tactics, and any Anti-Marleyan Volunteers who shows signs of betrayal will be killed by her without mercy.

He followed Zeke almost fanatically and strongly agreed with his "Eldians euthanasia" philosophy.

After coup d'état with the Yeagerists and seizing control of the military government, he publicly revealed his Euthanasia Plan. Because it contradicted the ideals of reviving the Eldian Empire, he was arrested by the Yeagerists led by Floch. He was later publicly tried and executed by firing squad by the Yeagerists, but was rescued by Jean and the Cart Titan. The request to rescue Yelena was made by Magath, because he believed that Yelena, who had taught Eren about the continent, knew Eren's possible location.

Yelena refused to help and angrily rebuked Marley. Pieck then revealed the results of his previous investigation: Yelena was actually originally a Marleyans, but out of disappointment with Marley, she disguised herself as a soldier of another country with Zeke's help, her only goal being to save the world with Zeke and make a name for herself in history. However, Yelena then made sarcastic remarks about everyone present. Currently, she is traveling with Marley and the Survey Corps, who have allied to stop the Rumbling, but their objective remains unclear.

A dark-skinned male air force lieutenant in the Marleyan military, a technician, the designer of the first harbor on Paradis Island after learning the truth about the world, who knows how to pilot a spaceship, and does not discriminate against the Eldians.

Together with Yelena, they accepted Zeke's orders to make contact with Paradis Island and infiltrate the Marley army. In cooperation with Yelena and the Survey Corps, they successfully captured all the Marley soldiers on the Marley reconnaissance ship. Together with the Marley engineers on the ship, they introduced new technologies to Paradis Island, such as trains, airships, automatic weapons, and radios.

When Sasha asked her why her skin was black, she replied to the Survey Corps, "Because God wanted it this way, and thought it would be more interesting to have different races." Therefore, she was not surprised or discriminated against by the Eldians who could transform into Titans.

He seems to have a particularly good relationship with Hange and the Survey Corps members. In chapter 118, after initiating the riot, he changed his attitude towards Hange and the others. After hearing Yelena's account of Zeke's purpose, he disagreed with Zeke's "Eldians euthanasia" ideology. After the Marley invasion, seeing the unfavorable situation, he released the Survey Corps and others, and also released other captured high-ranking officers of the Legion. After the battle Shiganshina District and Marley, all the Anti-Marleyan Volunteers members, including Onyankopon, were arrested by the Yeagerists on charges of treason for their Euthanasia Plan.

He was publicly tried and executed by firing squad for disagreeing with the Yeagerists's ideology. During the trial, he accused the Yeagerists of extreme nationalism and militarism, and pointed out that the Anti-Marleyan Volunteers' help on the island had resulted in the destruction of his homeland. He was later rescued by Jean and the Cart Titan, expressing his gratitude to Jean. Currently, he is working with the Survey Corps and Marley to stop the Rumbling. While flying to Fort Salta, his plane was hit by debris from the Beast Titan, and he managed to make an emergency landing on the fortress runway, but he fell into a temporary coma.

After the failed recapture of Maria, Marley, preoccupied with its war in the Middle East, sent fleets to investigate Paradis Island for four consecutive years in an effort to assess its strength. However, the fleets were captured by Eren's Attack Titan, Armin's Colossal Titan, and the "Anti-Marleyan Volunteers" lurking within the Marley fleet. The captured Marley soldiers were spared from being killed by the Eldian military government due to their connection to Elena, a member of the Anti-Marleyan Volunteers Army. The government assigned them tasks based on Marley abilities and granted them a degree of freedom.

However, this led to the alcohol laced with Zeke's spinal fluid being brought into the restaurant where the Marleyans worked, and being consumed by high-ranking members of the Legion (it has been confirmed that some members of the Military Police Brigade's high command drank it). Subsequently, they followed Yelena in supporting the "Yeagerists," launching a coup in the military government to seize control of all the Legion's high command, and imprisoning Armin Arlert, Mikasa, and other Survey Corps. One of them was killed by Yelena with a gun for verbally insulting Armin Arlert and the others.

Marleyan military Navy Private First Class, who was a cook, was a Marley soldier who came to Paradis Island with the first survey fleet. He was captured by the Survey Corps led by Hange during the landing. Later, through the introduction of Elena, a member of the Anti-Marleyan Volunteers, he worked as a cook on Paradis Island.

Initially, he feared and loathed the Eldians on the island, even calling the Survey Corps demons. However, as time went on, he got along well with the 104th class of the Survey Corps and developed feelings for Sasha because Sasha particularly liked his cooking. In chapter 106, after learning of Sasha's death in battle, he went to Sasha's grave to mourn and expressed his wish to invite Sasha's family members who came to pay their respects to have dinner at the restaurant where he worked.

In chapter 111, after learning that Gabi had killed Sasha, he was furious. He then tried to smash Gabi with a bottle and handed a knife to Sasha's father, asking him to avenge his daughter. However, he let Gabi go after being persuaded by Sasha's father.

The attitude towards the Eldians also seems to have changed.

After the Yeagerists's rebellion, he was imprisoned along with Armin, Mikasa, Jean, Connie, and the Blouse family, but his treatment was better than the others (his cell had a kitchen). After Marley launched a surprise attack, he agreed to release everyone from the Survey Corps, and Jean ordered him to protect the Blouse family's safe escape. Because the passage out of Shiganshina District was blocked, he had to take his family to hide in a nearby house, where their conversation was overheard by Kaya and the others.

A Marine First Class in the Marleyan military, and a contemporary of Niccolo. He harbors deep-seated prejudice against Eldians. As one of the Marley soldiers who arrived on Paradis Island with the survey fleet, he is extremely prejudiced against Eldians. After being captured by the Survey Corps, he works in the kitchen alongside Niccolo. Later, he joins the Anti-Marleyan Volunteers and the Yeagerists, taking orders from Yelena. He learns of the plan to control the army using red wine and instructs Niccolo to prioritize supplying the survey fleet's red wine to the army's high command. However, noticing Niccolo's increasingly close relationship with Eldians, especially Sasha, he fears revealing the plan and therefore does not disclose its details to him.

When Hange led the 104th Generation and Onyankopon to investigate the restaurant, they were occupied by Eren and Floch's Yeagerists members, who captured Hange and her group. In chapter 116 of the manga, Sasha was humiliated in front of Niccolo and the 104th Generation outside the prison of the Shiganshina District Legion headquarters. Yelena, in order to gain the support of the 104th Generation for the upcoming public announcement of the Eldian Euthanasia Plan, Irena shot and killed the insolent Grior in front of him and apologized for his remarks.

Reiner's mother, Gabi's aunt, is gentle and dotes on Reiner, taking great pride in Reiner becoming Marley warrior.

Karina had an affair with Reiner's biological father (Marleyans) and gave birth to Reiner. Due to Marley law, the family could not reunite, so she hoped Reiner could become an "honorable Marleyans" so that they could be reunited. However, this was actually a white lie to Reiner. Although Reiner's biological father cared about Reiner, he was terrified of the Eldian mother and son, especially fearing that the Marley government would investigate Reiner after he inherited the Armored Titan. The unpleasant meeting with his biological father completely shattered Reiner's dream of family reunion. Karina was completely unaware of the unpleasant meeting between Reiner and his biological father, and continued to tell Reiner the white lie as Reiner was about to go to Paradis Island to fight for the Founding Titan. She was the driving force behind Reiner's tragic fate.

After the Battle of Fort Slava, in addition to being happy that Reiner had returned safely, he was also very pleased Gabi Gabby had made great contributions in the Battle of Fort Slava. So he held a victory celebration at home for the Braun family, but he was worried about Reiner's metaphorical sharing about his military experience on Paradis Island.

When Willy Deba gave a speech in Liberio, he was invited to attend along with other warriors' families. He spoke with Annie's father and mentioned the news of Bertolt's father's death.
