Chūya Nakahara

Biodata

Background

Chūya was a test subject in a military artificial-ability project and Arahabaki’s human vessel. The French Concession explosion marked his birth; unlike Kamiki Yūhaku, another survivor of the experiments, Chūya did not remember the events beforehand 8 9 13.

During the Dragon Head Conflict, Chūya and Osamu Dazai worked together to stop the violence. Kamiki also assisted their investigation by identifying the person who started the conflict, although he and Chūya did not come to know each other well 7 12 13.

Appearance

Chūya is short, though his presence stands out among the people around him 7.

• He wears a black coat and a tall hat 7.
• His ability appears as an orange-red aura when he uses it 8 31.

Personality

Chūya is fiercely loyal to the Port Mafia and takes threats against it seriously. He is also quick to anger: Kamiki’s insinuation that he was a manufactured weapon provoked him into attacking 6 7 8.

Despite his initial hostility toward Kamiki, Chūya empathizes with what he endured. He challenges the government’s treatment of him, seeks medical help for his injuries, and eventually respects his refusal to abandon the past 12 18 20.

Abilities & Skills

Upon the Tainted Sorrow

Chūya’s ability allows him to manipulate the gravity of things he touches 8.

• He made Kamiki’s dagger heavy enough to warp it, then sent it back against him 8.
• He shattered Kamiki’s blood-triggered defensive ability with greater force and hurled him to the ground 8.
• He lifted and held rubble above the ruins of the Number Seven Agency so Ango could reach Kamiki 31.

Corruption

Chūya has an immensely destructive form that cannot be controlled once released 8.

• During Yokohama’s fog crisis, he used Corruption to fight and destroy the dragon, forming black holes from gravity particles 13.

Relationships

• Kamiki Yūhaku — A former Port Mafia intelligence agent and fellow experimental subject. Chūya pursued him after the warehouse bombing, but later sought to save him and helped recover him from the Number Seven Agency’s ruins 7 12 16 31.
• Ōgai Mori — The Port Mafia boss. Mori ordered Chūya to investigate Kamiki and later permitted him time to act independently, while warning him that Kamiki was dangerous 7 16.
• Kōyō Ozaki — A fellow Port Mafia executive whom Chūya calls “Big Sis Kōyō.” She helped Mori identify Kamiki after the attack on headquarters 6 7.
• Osamu Dazai — A former Port Mafia executive and Chūya’s partner during the Dragon Head Conflict. Despite their antagonism, they cooperated in efforts to save Kamiki 6 7 16 21.
• Ango Sakaguchi — A former undercover agent in the Port Mafia and a member of the Special Division for Unusual Powers. He gave Chūya information about Kamiki’s experiments, and the two later searched the Number Seven Agency’s ruins together 12 31.

Story Role

The Port Mafia attack

After a weapons warehouse explodes, Chūya meets Kamiki disguised as a guard outside Mori’s office. Once the deception is discovered, he frees two guards and retrieves Kajii Motojirō, who has been left hanging outside the building. Mori identifies Kamiki and orders Chūya to investigate 6 7.

Chūya finds Kamiki and fights him after Kamiki taunts him about his origins. Before escaping into the white fog, Kamiki reveals that a bereaved mother commissioned the attack and hints that he was also an experimental subject 8 9.

The fog crisis

After recovering his ability, Chūya accepts a commission from the Special Division for Unusual Powers in exchange for information about Kamiki’s past. Ango shows him records of the experiments and asks him to save Kamiki. Chūya goes on to destroy the dragon while Kamiki watches 11 12 13.

Trying to save Kamiki

With Mori’s permission and Dazai’s help, Chūya searches Port Mafia records for clues to Kamiki’s past. He discovers that Kamiki used the organization to destroy the Kōrai-kai in revenge for the death of Kambe Kazuha, the doctor who had rescued him 16 19.

After Kamiki destroys a research facility, Chūya takes him to a black-market physician and urges him to care for himself. Their conversation ends in the rain, with Chūya giving him an umbrella and deciding not to force him to abandon his past. Chūya and Dazai subsequently agree to let Kamiki confront the government while arranging support if he survives 18 20 21.

When the Number Seven Agency is destroyed, Chūya and Ango search the wreckage. Chūya lifts the stones, allowing Ango to find Kamiki alive with Little Crow in his arms 31 32.
