Description
Naoto Tachibana is the younger brother of Hinata Tachibana and a key supporting character in Tokyo Revengers. He is introduced as a timid middle school boy who gets bullied by delinquents, but after a meeting with Takemichi Hanagaki in the past, his life takes a dramatic turn. In the present timeline, Naoto works as a detective in the organized crime department of the Tokyo police. His personality as an adult is serious, no-nonsense, and driven by a strong sense of justice. He is highly intelligent and methodical, using his deduction skills to piece together scraps of information and gather classified intelligence on the Tokyo Manji Gang. Despite his often stern demeanor, Naoto is deeply emotional about his sister's fate and is determined to change the past to save her life.

Naoto's central role in the story is as the catalyst for Takemichi's time-leaping ability. Physical contact, specifically a handshake, triggers Takemichi to travel twelve years into the past or back to the present. Acting as Takemichi's primary ally and informant in the present, Naoto provides vital information, resources, and strategic support. Over the course of the series, including the War of the Three Titans Arc, he remains a steadfast partner, though his initial anger and desire for violent solutions evolve into a more nuanced understanding of Takemichi's methods.

His key relationships are with his sister Hinata, whom he loves and protects, and with Takemichi, who becomes both a friend and a collaborator. Naoto also shares a complicated connection with the Tokyo Manji Gang, particularly Mikey and the other leaders, as he investigates their criminal activities. His development is marked by a transition from a victimized child to a capable law enforcement officer who learns to trust in Takemichi's unorthodox approach, even when it contradicts his own pragmatic instincts.

Notable abilities include his sharp deductive reasoning, his access to police records and intelligence networks, and his growing proficiency in handling weapons and combat as the story demands. His unique position as the only person who fully understands and can facilitate Takemichi's time leaps makes him indispensable. Throughout the War of the Three Titans Arc, Naoto continues to support Takemichi from the present, using his knowledge and resources to help navigate the escalating conflict between the remaining gang factions.
