Plot

The story takes place in a dystopian 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" (or "Rat") on the former's twelfth birthday. What Shion soon discovers is how drastically life will change after meeting with the mysterious Nezumi, with whom he had shared one unforgettable, stormy night.

Characters

;
:
:Shion is an intelligent and idealistic boy living in the dystopian city of No. 6. At age 12, he shelters Nezumi, a fugitive, and is subsequently stripped of his elite status, forced to relocate to the impoverished Lost Town. Four years later, while working in park maintenance, he uncovers a government cover-up involving parasitic wasps that kill his coworker. Arrested, he is rescued by Nezumi and taken to West Block. After surviving infection—which leaves him with white hair and a serpentine scar—he grapples with the harsh realities of his world. Over time, his bond with Nezumi deepens into romantic love, culminating in a farewell kiss before Nezumi departs.

:
:Nezumi is a cynical and resourceful 16-year-old living in West Block after fleeing No. 6’s authorities. Four years earlier, wounded and on the run, he encountered Shion, who sheltered him despite the risks. Now a skilled fighter and performer under the stage name Eve, Nezumi harbors deep resentment toward No. 6, which destroyed his village. When Shion is arrested, Nezumi rescues him, and the two take refuge in West Block. Though initially aloof, Nezumi grows deeply attached to Shion, his feelings evolving into love. After a near-fatal confrontation, he shares a passionate farewell kiss with Shion before departing, leaving their future uncertain.
;
:
:Dogkeeper is a brash but resourceful resident of West Block who operates a rundown hotel and rents out dogs as living heaters during winter. Running various underground trades, including dealing in goods smuggled from No. 6’s Correctional Facility, they share a contentious yet cooperative relationship with Nezumi, often exchanging information. Raised by a dog they call "Mother", Dogkeeper deeply cares for canines and sometimes requests Nezumi to sing for deceased ones. Their gender remains ambiguous—while referred to with masculine pronouns in English translations, the novels suggest they may have been assigned female at birth.
;
:
:Safu is Shion's childhood friend and a neurobiology prodigy in No. 6. Before leaving to study in No. 5, she confesses her feelings to Shion, who gently rejects her, valuing their friendship instead. Her time abroad alters her perception of No. 6, making her question its supposed utopian ideals. After her grandmother's death, she returns, only to be captured by No. 6's authorities and imprisoned in the Correctional Facility, where she becomes a test subject for inhumane experiments. Her ordeal highlights the city's hidden brutality.
;
:
:Shion's mother runs a bakery in Lost Town after being exiled from Kronos alongside her son. When authorities falsely accuse Shion of murder and imprison him, she despairs until Nezumi covertly informs her of Shion's escape to West Block using messenger mice that evade city surveillance. Though deeply concerned for her son's safety, she resolves to persevere, maintaining hope for their eventual reunion. Her resilience reflects quiet defiance against No. 6's oppressive system.
;
:
:A West Block resident and former journalist, he operates a pornographic magazine while secretly managing a prostitution ring serving No. 6's officials, funding his luxurious lifestyle. Though an admirer of Nezumi's theatrical persona Eve, he receives only contempt from Nezumi himself. His past romantic feelings for Karan result in occasional kindness toward her son Shion, contrasting with his otherwise self-serving behavior.

Development

The concept of ''No.6'' was inspired by the September 11 terrorist attacks in 2001. Atsuko Asano watched the attack on television, causing her to ponder the nature of conflicts between an individual and the state, and wrote ''No.6'' based around those themes. She has also described being influenced by the manga ''Banana Fish''; highlighting the action elements, love between boys, and the relationship between a country and an individual as examples.
