Description
Naoto Tachibana, younger brother of Hinata Tachibana, serves as a detective specializing in organized crime. His childhood featured black hair parted to the right, a slender frame, and school attire of collared shirts, black slacks, and loafers. As an adult, his serious demeanor is accentuated by a gray coat, maroon tie, and glasses, embodying his professional rigor. Reserved yet analytical, he prioritizes logic over humor, leveraging pragmatism to dismantle criminal networks.

Bullied frequently as a child, his life shifted when Takemichi Hanagaki intervened, later disclosing Naoto’s and Hinata’s doomed 2017 fate. This revelation drove Naoto to pursue law enforcement, aiming to thwart their deaths by infiltrating groups like the Tokyo Manji Gang. His willingness to embrace anomalies—such as Takemichi’s time-leaping—fuels their alliance, blending open-mindedness with relentless resolve.

Central to their strategy is the handshake-triggered time-leap, enabling 12-year temporal shifts. Naoto deciphers its rules, including temporal synchronization, while supplying Takemichi with gang intelligence on figures like Manjiro Sano and Tetta Kisaki. Though timelines shift—Hinata surviving one scenario only to perish later—their mission faces relentless complexity, exposing the fragility of altered futures.

Naoto transitions from behind-the-scenes informant to active participant, tracking figures like Nobutaka Osanai to unravel gang conspiracies and collaborating against threats like Tenjiku. Repeated losses of Hinata across timelines strain his resolve, yet he adapts, targeting Kisaki’s influence with precision. His law enforcement access and tactical intellect prove indispensable in navigating gang wars and temporal paradoxes.

Disliking karaoke but favoring libraries, Naoto practices calligraphy and admires occultist Aleister Crowley, juxtaposing scholarly curiosity with a fear of Hinata’s wrath. Childhood passivity—enduring bullies and complying with Takemichi’s odd requests—contrasts his adult assertiveness, marking his evolution from vulnerability to strategic mastery.

Later efforts expose Kisaki’s schemes and reduce gang violence, yet stable outcomes remain elusive. Interactions with Ken Ryuguji and Atsushi Sendo underscore moral gray areas, where victories spawn unforeseen repercussions. Despite despair, his bond with Takemichi endures, anchoring their quest to forge a timeline where Hinata lives.
