Determined to uncover the truth, Hiroshi began to investigate the attack. With the help of Kenji and a few trusted allies, he delved into the city's underworld, following leads and gathering information. It wasn't long before he discovered Taro's involvement.
Confronting Taro was a dangerous endeavor, as the rival merchant's son had powerful connections and resources. Hiroshi knew he needed solid evidence to expose Taro's treachery. With Aiko's support, he continued his investigation, all the while keeping a low profile to avoid further attacks.
One night, while secretly following one of Taro's henchmen, Hiroshi overheard a conversation that confirmed Taro's plans. The henchmen discussed their orders to eliminate Hiroshi and discredit him in the eyes of Lord Takeda. Armed with this information, Hiroshi knew he had to act swiftly.
