Chapter Summaries

Koizumi insisted on preparing himself for future fights and asked Shizune to investigate Ouka the Ogre, while he planned an assassination mission with Akame and Chelsea. Chelsea tried to tease him, but Koizumi kept getting distracted, leaving her questioning whether he noticed her charm.

• Reimu worried Koizumi had never killed anyone, but Koizumi said he would not stand behind others while they risked their lives.
• Koizumi asked Shizune to investigate Ouka the Ogre in the capital and report everything she learned.
• Koizumi considered how to assassinate Reias and his family despite the capital’s increased security and the limits of Chelsea’s Imperial Arm.
• Chelsea approached Koizumi to test his character and teased him by moving close, causing him to stumble before Akame caught him.
• Chelsea bragged about being more attractive than Mine, but Koizumi became distracted by thoughts of two people and ignored her flirtation.

Koizumi, Akame, and Chelsea prepared to ambush Reias outside the Imperial Capital, though Akame and Chelsea secretly planned to follow Koizumi if he entered the city alone. As Reias headed to the dangerous beast settlement with guards and the twin sisters Lia and Lie, Chelsea resolved to spare Akame the burden of killing her sister Kurome herself.

• Koizumi rejected Chelsea's suggestion to assassinate Reias inside the Imperial Capital, citing its heightened security and the danger Akame would face there.
• Koizumi said he would handle the rest of Reias's family alone after Akame and Chelsea dealt with Reias, but both women decided to follow him in secret.
• Koizumi, Akame, and Chelsea reached the dangerous beast settlement to study its terrain and plan an escape route.
• Akame recalled training there with Kurome, and Chelsea decided she would kill Kurome so Akame would not have to kill her own sister.
• Reias left the Imperial Capital with his guards and the twins Lia and Lie, whom he had lured into trusting him.

Koizumi, Akame, and Chelsea waited in ambush while discussing the Revolutionary Army and prepared to confront Reias. Elsewhere, Seryu struggled with the revelation that Ouka was corrupt, while Lia and Lie fled Danger Beasts until Koizumi and the others arrived to fight their pursuers.

• Chelsea explained that she and Akame knew little about the Revolutionary Army's inner workings, so Koizumi planned to ask Najenda or Serenity about its Servants and secrets.
• Akame reassured Koizumi that Leone's assessment of Reias's behavior was reliable, then sent Chelsea to scout as screams and Danger Beast roars sounded nearby.
• Serenity infiltrated the Imperial Guard and found Seryu leading it under General Bude's command while Ouka was absent.
• Seryu regretted trusting Ouka and missed the peaceful days she had spent with Koizumi, Reimu, and Hata no Kokoro; a shadow passed unnoticed nearby.
• Lia and Lie fled through the forest after Reias turned against them, but a dinosaur-like Danger Beast cornered them as Koizumi, Akame, and Chelsea began fighting their target.

Koizumi and Akame rescued Lia and Lie from a Danger Beast, then confronted Reias and the guards who had abandoned the sisters in the forest. Koizumi fought the guards himself, discovered that killing and tasting human blood awakened more of his vampire power, and Chelsea pursued the fleeing Reias.

• Lia shielded Lie from a dinosaur Danger Beast, but Koizumi and Akame arrived and Koizumi felled it with Gungnir.
• Akame praised Lia for protecting her sister, while Koizumi mocked the wounded Danger Beast and drew suspicion from Akame with his bloodthirsty aura.
• Reias arrived with his guards, recognized Akame, and was identified by Lia and Lie as the man who had left them in the forest.
• Reias ordered the guards to attack, but Koizumi stopped Akame from intervening and charged into battle himself.
• Koizumi swiftly killed several guards, and tasting human blood intensified his vampire power and increased the pressure of his aura.
• Chelsea transformed into an eagle and flew after Reias as Akame watched Koizumi's strength rise.

Koizumi killed Reias’s accomplice while Chelsea assassinated Reias, then agreed to bring Lia and Lie to Night Raid after they asked to follow him. Najenda approved their arrival, partly because she understood Akame’s concern for the twin sisters.

• Koizumi killed the vicious man with Gungnir, and Akame checked that he was not troubled by killing for the first time.
• Chelsea returned with Reias’s body after disguising herself to get close and killing him with a poisoned needle.
• Lia and Lie asked to follow Koizumi, and he discussed bringing them to Night Raid with Akame and Chelsea.
• Koizumi warned Lia and Lie that Night Raid’s life was harsh and dangerous, but they chose to stay with the group.
• Najenda agreed to take the sisters in and recognized that Akame’s concern for them came from thinking of Kurome.

Koizumi learned that General Bude had taken control of the Imperial Guard, making an Imperial Capital infiltration far more dangerous, and Najenda explained why Bude’s intervention broke his family’s longstanding rule against political affairs. Koizumi prepared to investigate Bude and find Seryu, then assembled a team for the mission.

• Najenda agreed that Akame could keep Lia and Lie safe, while Koizumi returned to his room to await Serenity and plan a possible visit to Seryu.
• Serenity reported that Ouka had likely been executed by General Bude and that Seryu was confused; she also revealed that Bude had taken over the Imperial Guard.
• Najenda warned that Bude’s troops made infiltrating the Imperial Capital extremely dangerous, and Koizumi decided he might need to enter alone.
• Najenda explained that Bude’s family commandment forbade political involvement, making his personal purge of the Imperial Guard deeply suspicious to her.
• Koizumi prepared for the mission with Mine, Sheele, Akame, and Chelsea, while Mine complained about having to follow his orders.

Koizumi infiltrated the Imperial Guard base with Chelsea to find Seryu and take her away from the Imperial Capital. He reunited with her and expressed concern for her safety, while she welcomed his familiar warmth.

• Akame and Sheele stayed behind to protect Mine while Koizumi and Chelsea set out for the Imperial Capital.
• Chelsea transformed into a bird and rode on Koizumi’s shoulder as he flew over the city and searched for the Imperial Guard base.
• Koizumi told Chelsea he planned to take Seryu Ubiquitous away because he did not want to become her enemy or leave her in the Imperial Capital.
• Koizumi entered the base and greeted Seryu, while Chelsea slipped outside to keep watch.
• Seryu was startled to see Koizumi, then felt relieved as he explained that he had returned because he was worried about her.

Koizumi persuaded Seryu to trust her own judgment and led her to the Reias residence to show her the Empire’s hidden evil. After Chelsea slipped inside to deal with the guards, Koizumi and Seryu waited outside in the dark, leaving Seryu unsure what they would find.

• Seryu told Koizumi she did not consider him evil and would not arrest him solely because he was wanted.
• Koizumi reasoned that General Bude’s pursuit of him, Reimu, and Hata no Kokoro might have a hidden cause, then warned Seryu about the Imperial Guard patrols.
• Koizumi took Seryu through the streets to the Reias residence and said he would show her the Empire’s true darkness.
• Chelsea transformed into a fly and entered the residence to clear out guards while Koizumi and Seryu hid in nearby grass.
• Seryu watched the dark residence and shivered in the cold as she waited to see what Koizumi meant.

Koizumi brought Seryu into Reias's mansion to show her evidence of the nobles' crimes, while Chelsea secretly killed the guards and kept watch outside. After reading Reias's diary, Seryu's faith in the nobles collapsed, and she asked Koizumi whether he belonged to Night Raid.

• Koizumi explained that he and Seryu needed an opportunity to enter the mansion without drawing suspicion, then revealed that the kitten following him was Chelsea using Transformation Free: Gaia Foundation.
• Chelsea poisoned the guards, hid their bodies, and transformed into a kitten to watch the estate while Koizumi led Seryu inside.
• Koizumi found Reias's diary in his room and handed it to Seryu, who read its account of the nobles' oppression of outsiders.
• Seryu realized that the nobles she had protected were evil, questioned the justice she had upheld, and felt her worldview collapse.
• Seryu calmed herself and asked Koizumi whether he was with Night Raid.

Koizumi revealed that he belonged to Night Raid and challenged Seryu's understanding of justice while killing the Reias family. Seryu abandoned the Imperial Guard and chose to leave with Koizumi and Chelsea, but they faced difficulty getting her out of the Imperial Capital undetected.

• Koizumi told Seryu he had joined Night Raid after leaving the Imperial Capital and showed her the diaries exposing the Reias family.
• Koizumi killed everyone at the Reias estate while Seryu watched, troubled by her own sense of satisfaction.
• Koizumi questioned Seryu about whether justice meant obeying the Empire or following her conscience, and she concluded that justice meant acting in a way she could live with.
• Seryu decided to leave the Imperial Guard and wanted to work alongside Reimu rather than remain behind as a spy.
• Koizumi, Chelsea, and Seryu considered how to escape the Imperial Capital without being spotted by patrolling Imperial Guard members.
