Takai serves as a disciplined police officer in Tokyo, partnered with Yasui. His imposing height, pale complexion, and sharply styled black pompadour frame a face marked by small, intense eyes and pronounced lower eyelashes, amplifying his austere presence. He adheres to a crisp professional uniform: a black suit paired with a red tie. Rigorously logical and duty-bound, he approaches cases with unwavering focus, prioritizing protocol over personal sentiment—a contrast to his partner’s methods, reflecting his newcomer status on the force. Tasked with apprehending Hodaka Morishima, a minor suspected of illegal firearm possession, Takai methodically questions a host connected to the boy and reviews CCTV footage capturing Hodaka brandishing a gun. His investigation leads him and a female colleague to Hina Amano’s residence, where they inform her of impending social services intervention to remove her brother due to their unsupervised living situation. Tracking Hodaka to a hotel, Takai arrests both the fugitive and Nagi Amano after Hina vanishes. He escorts Hodaka to Ikebukuro Police Station for interrogation, but the teenager escapes. A chase ensues to Yoyogi Kaikan, where Keisuke Suga physically obstructs Takai, enabling Hodaka’s flight. Undeterred, Takai apprehends all involved parties, including Suga and Nagi. The manga adaptation extends his role, depicting an additional interrogation of Hidaka alongside the latter’s parents. His reactions to Tokyo’s catastrophic flooding and the final resolution of the case remain unexplored across documented media.
