Based on Fushimi Roku's deductions, Captain Minamoto Tamako meticulously planned the investigation's direction, dispatching the provisional team member Abe Rokuro to re-investigate the 'addicts' social circles, and personally led the team to the suspect's home in the "face-biting case" to gather evidence.
Minamoto Tamako thoroughly enjoyed her role as captain, always walking at the front when they were outside. Fujimura-kun couldn't walk too fast; if he outpaced her, it would be disrespectful to the captain, subtly showing off his long legs and implying that the captain's legs were relatively short—there was nothing wrong with her body-to-leg ratio, but compared to Fujimura-kun's height of 1.8 meters, her legs obviously weren't as long, hence the short-leg theory.
Fushimi Roku had to slow his pace, walking behind her like a little follower behind a princess.
