Koizumi trained with Hata no Kokoro to master Remilia's vampire power, but its nighttime influence nearly made him attack her. Meanwhile, Leone found Reimu and invited her to join Night Raid, but Reimu refused.

• Koizumi asked Hata no Kokoro to train with him, and they fought as he pushed himself to improve.
• As night fell, the vampire's consciousness threatened to take control of Koizumi, so Hata no Kokoro attacked him; Koizumi turned into bats and re-formed with his senses restored.
• Koizumi admitted he needed more training, while Hata no Kokoro promised to stay by his side in case his power went berserk.
• Leone followed Reimu's scent and approached her alone, but Reimu attacked with talismans before Leone could explain herself.
• Leone introduced herself as a Night Raid assassin and invited Reimu to join; Reimu rejected the offer and saw through Leone's attempt to use help finding her companions as persuasion.

Reimu agreed to make amulets for Night Raid in exchange for generous payment, then told Koizumi about the deal after he returned from training with Hata no Kokoro. Koizumi accepted her decision and sought information about Night Raid, while Reimu realized she had agreed without learning Leone’s name.

• Leone offered Reimu payment to make amulets for Night Raid, and Reimu accepted before settling the details.

• Reimu realized she had never asked Leone’s name, and Koizumi and Hata no Kokoro reacted with dismay.

Koizumi woke in a noble’s mansion with a painful gap in his memory and found himself surrounded by people he felt he knew but could not remember. Reimu learned the Imperial Capital’s distortion originated beyond Yakumo Yukari’s reach, while Koizumi remained unaware of what had happened to his companions.

• Reimu questioned Yakumo Yukari about the Imperial Capital, and Yakumo said its distortion came from a world she could not observe, leaving them to follow their original plan to contact Night Raid.
• Koizumi woke in a mansion, unable to find Reimu or Hata no Kokoro and suffering from a sharp headache.

• Koizumi asked Aerya who she was and where he was, and she became alarmed when she realized he had lost his memories.
• Sayo and Ieyasu were shocked by Koizumi’s amnesia as he recognized none of them, despite feeling familiar with them.

Koizumi went with Aerya, Ieyasu, and Sayo to the enlistment office and discovered the capital had no wanted posters for him, while Akame fought her former friend Myako and was joined by Tatsumi. Nearby, Kurome was attacked by fanatical residents, and Koizumi stepped in to protect her as the crowd turned on him too.

• Koizumi concealed his past clash with the Imperial Guard and accompanied Aerya, Ieyasu, and Sayo to the enlistment office.
• Koizumi noticed there were no wanted posters of him in the capital, but saw a poster for Akame and sensed hostility among the residents.
• Myako attacked Akame, who held back and urged her former friend to leave rather than fight to the death.
• Tatsumi arrived during Akame and Myako's fight and knocked Myako's weapon aside.
• Koizumi found Kurome surrounded by residents throwing stones and called her by name, despite not understanding how he knew her.
• The residents threatened Koizumi for defending Kurome, and Kurome moved in front of him as they raised clubs and hoes.

Koizumi defended Kurome from hostility in the Imperial Capital, where she sensed the citizens’ loyalty to the Empire had become unnaturally fanatical. Esdeath arrived, recruited Kurome, and gave her a path to find Akame before Esdeath could; Kurome asked Esdeath to train her.

• Kurome explained that her Imperial military registration protected her from punishment for Akame’s betrayal, though civilians still harassed her.
• Aerya, Ieyasu, and Sayo showed hostility toward Kurome, and Koizumi shielded her while deciding she needed information from Night Raid.

• Esdeath said Akame was alive and urged Kurome to grow strong enough to capture her before Esdeath did.
• Kurome accepted Esdeath’s challenge and asked the general to train her.

Esdeath agreed to train Kurome and invited her to the palace, while Koizumi decided to go with Kurome and her friends. As they prepared to leave, Koizumi continued concealing his lost memories and wondered what secrets lay behind the Empire’s changed citizens.

• Esdeath noticed the Command Seals on Koizumi’s hand, then left with her officers after Kurome accepted her offer of training.
• Koizumi rejected Aerya’s company and agreed to accompany Kurome to the palace, suspecting that the Empire concealed something.
• Kurome returned to invite Remusu, Gin, and Mamin to move into the palace with her, and Gin scolded Kurome for going out alone.

• Kurome and her friends packed their belongings, including Kurome’s cookies, and prepared to head to the palace.

Koizumi accompanied Kurome and her friends to Esdeath’s estate, where he encountered General Budou and learned that the Empire seemed to be in an unexpectedly peaceful era. After Esdeath brought them to her training grounds, she suddenly attacked Koizumi, forcing him to reveal his vampire form and defend himself.

• Koizumi entered the imperial palace with Kurome and the others, while Kurome said she was excited to find a way to reunite with her sister.
• General Budou left Esdeath’s residence after threatening to eliminate her, and Koizumi grew suspicious when Esdeath complained that the Empire had no war or worthy opponents.
• Esdeath led Kurome, Koizumi, Gin, Mamin, and Remusu to the training grounds and introduced them to her Three Beasts: Liver, Nyau, and Daidus.
• Kurome trained with March of the Dead: Yatsufusa against Gin, Mamin, and Remusu, while Esdeath lamented that Kurome had not received proper training.
• Esdeath suddenly sent a massive ice spike at Koizumi, who blocked it with Gungnir, took to the air, and transformed into a vampire as she prepared to fight him.

Koizumi fought Esdeath, who wanted to test and train her, while Kurome and the others battled ice cavalrymen. After hours of brutal combat, Koizumi had learned to track Esdeath but was still decisively outmatched, and Esdeath was satisfied with the training.

• Esdeath attacked Koizumi because she wanted a worthy opponent, and Koizumi dodged her ice spikes before trading blows with her.
• Esdeath wounded Koizumi repeatedly and engulfed her in an ice storm, but Koizumi survived by transforming into bats and reassembling herself.

• Koizumi ended the fight pale and covered in wounds, while Esdeath felt satisfied after indulging her desire to battle.

After Koizumi’s brutal spar with Esdeath, he suffered a mysterious attack of pain in his sleep, which Reimu eased with talismans. He later waited with Reimu and Hata no Kokoro for Night Raid to arrive and discuss their deal.

• Koizumi acknowledged how much his strength had improved after sparring with Esdeath, while Kurome and Gin reacted to his injuries and fighting ability.
• Koizumi returned to his room to rest and experienced intense pain throughout his body in a dream, then woke to find Reimu and Hata no Kokoro beside him.

• Koizumi, Reimu, and Hata no Kokoro waited for Night Raid, while Reimu grew impatient and Koizumi explained why the group might be delayed.

Koizumi confronted Leone, who had stolen his money, when she brought Night Raid's Boss Najenda to meet him and Reimu.

• Reimu and Hata no Kokoro detected threads sealing off the area as Leone arrived with Najenda.
• Koizumi recognized Leone as the person who had stolen his money, and Reimu's opinion of Night Raid worsened.

• Koizumi used a Command Seal to stop Reimu from accepting money alone, then requested detailed intelligence from the Revolutionary Army in exchange for charms.
• Najenda asked why Koizumi wanted the intelligence, but he refused to reveal his purpose, so she left to consult the Revolutionary Army's higher-ups.

Najenda considered how to persuade the Revolutionary Army’s leaders to accept Koizumi’s group’s intelligence-sharing proposal, while Koizumi made his intentions clear and prepared for Night Raid to test his allies. As Koizumi continued training with Remilia’s power, his control and combat strength improved dramatically overnight.

• Najenda worried that the Revolutionary Army’s higher-ups might reject the deal or target Reimu, then heard headquarters’ arrangements and emerged to reassure Akame and Leone.

• Koizumi explained to Reimu that he had disclosed their purpose to avoid secretly gathering intelligence and risking a later betrayal, then asked her and Hata no Kokoro to guard him.
• Reimu and Hata no Kokoro watched Koizumi train with Remilia’s power, and Reimu was astonished by how much his control had improved since the previous night.
• Koizumi wielded Gungnir as powerful magical energy surged from him, while Hata no Kokoro worried that the vampire’s influence might overwhelm his human will.

Koizumi fought Hata no Kokoro and managed to wound her before losing, impressing Reimu with how quickly his strength had grown. After Reimu sensed Night Raid’s forces entering her barrier, she and Hata no Kokoro confronted them, leaving Reimu fighting Leone and Mine while Akame and Bulat faced Hata no Kokoro.

Koizumi was poisoned by a female Assassin and lost consciousness, but awakened within a strange inner space protected by Yakumo Yukari’s power. He recognized the whirlpool he had glimpsed as the Swirl of the Root, leaving his survival and the nature of his connection to it unresolved.

• Hata no Kokoro noticed Koizumi’s huge magical attack and intensified her fight against Akame, Bulat, and Lubbock, while Mine and Sheele left for the base and Leone invited Reimu along.

• Koizumi found himself in a dark inner space, saw a whirlpool he identified as the Swirl of the Root, and realized Yukari’s power had protected him.

Koizumi survived the skull-masked girl's poison, gained access to the edge of Yukari's power, and fought NIGHTRAID's Assassins before Najenda stopped the confrontation and invited him to their headquarters. There, he reunited with Reimu and Hata no Kokoro and agreed to discuss cooperation with NIGHTRAID, while warning Najenda that his protective charms depended on receiving intelligence.
