That night, Nagumo reappears in Kiyomi's bar and once again asking Kiryu for a fight.

Shortly after Kiryu goes back into the bar, he was beaten up by the Masuzoe family who demands to know why Nagumo's late for bringing in the protection money. Kiyomi decided to give her money to Nagumo, but he refuses it; Telling her that if he accepts the money, he can never return to her bar as a customer anymore.

Later, Nagumo introduces Kiryu to Hirose and they both chats for a while. Suddenly, Matsunaga arrives and calls Nagumo out. He reports that he picked a fight with a customer and Yuuta said that ever since Kiryu beat them in baseball, their reputation has been decreased lately. Nagumo tells Matsunaga to take the hits instead of fight back against the customers because it's not how they handle businesses. After the rest of Hirose family left to handle with the customers, Nagumo apologizes to Kiryu for his friends' bad manners and tells him that he's welcomed here anytime.
The next day, when Kiryu come and ask him and the others about Haruka, Nagumo becomes nervous and tried to avoid him. But later that night, he come and tells Kiryu everything he knows.

His friends also want to assist him, but then Hirose shows up and decided to provide them with masks in order to conceal their faces so that no one could identify them. After planning their assault, he, alongsides Kiryu and his fellow family members attack the hotel to rescue Kiyomi.
After taking out the goons in the bathroom, Nagumo accidentally takes off his mask because he's feeling too hot.
