A recap of
the previous film explains that Jo, Chu, Eri, and Kenta defeated Yasuda and then defeated Ueno, a yakuza kingpin posing as the priest of the Love Cult Church. On a refrigerator delivery, Kenta mentions not enjoying delivering things to city hall. Jo thinks that she is still thinking like a yakuza, but it turns out that she is avoiding a boyfriend who works in city hall. The police receive a letter from Katsumasu Kawahara, First Secretary to Yasuo Nakata, Vice President of the Liberal Democratic Party, detailing Nakata's crimes. Detective Mizuta wants to investigate, but the police chief, using the codename "Yaraposki", calls Nakata to warn him about the person seeking to expose him. Kawahara is garroted by a bearded man with a
tracheal tube on his way to meet with Mizuta. Chu uses his lockpicking skills to help Kawahara's daughter Mio, who has locked her keys in her car. Mio later calls Angel Delivery to help her move and gives Chu a pair of her father's shoes as a gift. Chu discovers a strip of
negative film in one of the shoes showing donations of millions of yen to various retirement homes, but when Jo and Eri visit the Sunflower Home, they find the residents wearing cheap clothing such as straw sandals. Kenta suggests that the money is being funneled elsewhere. Nakata's boss tells him to get the film negative back in two days. At the Angel Delivery office, the bearded man knocks out Eri and fights with Chu, but Kenta's return causes the man to flee. Mizuta shows Mio her father's letter and she agrees to get the film negative and give it to him the next day. The bearded man sneaks into Mio's home and kidnaps her, then makes her call Chu and ask him to come alone with the film negative. Chu goes alone and is caught by the bearded man, who takes the film negative, but Jo follows him and saves him and Mio. Eri begins working at the Sunflower Home retirement home and snoops around the administrative offices. She does not find any financial records, but there is a large safe in one of the offices that is suspicious. Kenta mentions that her boyfriend in city hall told her that the director of the retirement home is the brother-in-law of an influential politician named Nakata. Chu reveals that he made a copy of the film negative. The police chief discovers some discrepancies in the film negative that he was given by the bearded man. The police stop Jo, Chu, and Kenta in their delivery truck and pretend that they have found drugs inside. Angered by the
frameup, Jo fights off the police and escapes while Chu and Kenta are arrested. Mio calls Mizuta for help, while Jo gets money from Mr. Abe. The police chief gives the film negative to Nakata, who gets back in his limo to leave, but Jo is inside and drives him to the Sunflower Home retirement home. Jo obtains the combination to the safe from Nakata's brother-in-law Koto, then lights dynamite to force Nakata to confess to causing Kawahara's murder, ordering the retirement home to funnel money for him, and hiring a hitman to kill the members of Angel Delivery. Eri uses a
camcorder to record Nakata's confession. Nakata says that he will claim he was coerced to say those things, so Jo brings in a tattoo artist who tattoos the words "dirty politician" to Nakata's forehead. As the police chief leaves his office, Mizuta appears with two other policemen holding a warrant to arrest the police chief for embezzlement and information trafficking. Nakata flees the country. The bearded man walks away freely. As the credits are rolling, Chu cries out "Hey wait!" The credits rewind, and Chu is shown distressed in prison. He screams, "Stop right there! Why did this happen to me? Why?! Let me out!" The screen fades to black, and the credits begin rolling again from the start. ==Cast==
