If Aoto remembers correctly — Ushiyama has 5 undercover informants, while Inagawa has a few more, employing a whopping 9 undercover informants.
When Aoto took over his father's position to enter the Fixed Town Patrol, the Tachibana family was already in debt, so naturally, Aoto didn't have extra money to hire undercover informants for odd jobs, and he had to do everything big and small himself.
When the Dōshin of Fixed Town Patrol patrol their jurisdiction, they usually have several undercover informants accompany them, so Chokata just asked Aoto, "Why don't I see your undercover informant?"
After succinctly informing Chokata about his current family situation, burdened by his late father's gambling debts, Chokata awkwardly apologized to Aoto:
"Sorry... I seem to have inadvertently brought up something I shouldn't have..."
"It's fine, no need to apologize." Aoto gave Chokata a carefree smile, "I don't mind."
The tea that Aoto ordered just now was brought up at this moment.
