Naru Ootori

As the younger sister of Kakeru, this bright and energetic girl initially appears to be quite innocent and naive. However, beneath her cheerful exterior lies a surprisingly sharp and perceptive personality. After enlisting Hayato's assistance to locate her missing bicycle, she reveals a quirky, specific obsession with worker uniforms. Her observant nature often catches others off guard, proving she is much more astute than her bubbly demeanor suggests.
