NO.6

The story takes place in the "ideal" and perfect city known as "No. 6". Shion, a boy raised in the elite and privileged environment of his home, gives shelter to another boy, who only gives his name as 'Nezumi' (Meaning Mouse or Rat) on the former's 12th birthday. After spending a rainy night with his new friend, Shion discovers the next morning that Nezumi has disappeared without a trace. Four years later, Shion experiences a spate of incidents around him in which a deadly infection by parasitic bees causes its victims to age rapidly and start to decompose at an alarming rate. Shion's co-worker is one of the victims and Shion is arrested on suspicion of murder. While Shion is being transported to the Correctional Institute, Nezumi appears and rescues him. Shion begins to find out the hidden truth behind the Ideal City No.6.

Shion (紫苑 (シオン))Voiced by: Yūki Kaji

Shion is an intelligent, idealistic individual who was on his way to going into the Special Curriculum for gifted students, specializing in Ecology, until his fateful encounter with Nezumi on his twelfth birthday. Although he knew Nezumi was a wanted fugitive he cared for the bullet wound in his arm (or shoulder in the manga adaptation), fed him, and sheltered him for the night in his room. Following a police investigation, he was punished for taking in a known fugitive and was stripped of his elite status in their caste-based society. He and his mother were forced to move from Chronos to Lost Town and he was no longer allowed to enter the Special Curriculum. Four years later, Shion works for Park Maintenance where he controls waste management robots. The job pays for his tuition, and he plans to go into the trades. One day, Sion and his coworker discover the body of an apparently old man in the park. When the man's death is not reported in the news, and Shion finds out that the body belonged to a man only 31 years old, he becomes suspicious of a government cover-up. Shion later witnesses his coworker age rapidly and a bee emerge from his neck. Shion is then arrested under the pretense of being suspected for murdering his coworker. Nezumi saves him from the authorities and takes him to West Block, the slums outside the city. Shion nearly dies himself when he is infected with a parasitic bee, but Nezumi saves him a second time, though Shion is left with white hair and scars that look like a red snake curling from his ankle to his neck. Later in the story, he works for InuKashi cleaning her dogs. He is childhood friends with Safu.

Nezumi (ネズミ?)Voiced by: Yoshimasa Hosoya

Nezumi is a intelligent, cynical boy around 16 years of age with a dark past. Four years ago, on his desperate run from No.6's police, he by chance found a house with an open window and went inside. Wounded and dripping wet, he met the room's occupant, Shion, a boy roughly his own age. Nezumi was shocked when Shion, despite understanding the danger of helping him and the lack of potential reward, treated his wound and sheltered him for the night. The next day he escapes to safety, and now lives outside of NO.6 in the West Block. When he learns that Shion is being forcibly transported to the Correctional Facility, he risks his life to save him. Together they escape to the West Block, and Nezumi invites Shion to live with him. Nezumi is a well known actor/actress under the nickname Eve and is talented in singing, acting and dancing. His home is filled to the brim with books, most of which are classics. He often quotes these books on the spot (specifically Macbeth and Faust). He is a skilled fighter and has very honed 'street smarts'. He despises the City of NO.6, calling it a "parasitic city" and has spent years trying to find a way to destroy it. Later in the story, we find out that the government of NO.6 perpetrated in the genocide of his people and he is is sole survivor of his village.
