Genre: Crime

After a tumultuous visit to her hometown, Yoshino and Kirishima return from Osaka to the Miyama residence in Tokyo. They thought their usual daily life would resume as always, but from the very next day, Yoshino starts ignoring Kirishima. She alters her schedule to avoid him when going to school, ignores him when he speaks, and offers no response even when he cooks for her. A rare moment of distress overtakes Kirishima, who sits in the rain in front of the annex where Yoshino is staying. What is the reason Yoshino continues to ignore Kirishima…?

Kirishima finds himself in the crowded chaos of a fireworks festival, while Yoshino and a group of delinquents gather nearby. Yoshino chases after Oz, who has been abducted by Naoya, while Kirishima blends into the crowd and launches a surprise attack on the delinquents. Targeted due to the incident involving Shiori Akaza, Yoshino is spotted by Naoya and faces imminent danger. Kirishima continues to take down the delinquents one by one, but a mysterious and dangerous figure, Azami Suo, suddenly appears before him.

"Where is Yoshino Somei?" Azami asks Kirishima. But what is Azami's true objective…?

From her seat on the bus, Nao spots Kirishima and Yoshino walking together. Unable to ignore them, she gets off at the next stop to follow. However, it's Yoshino who approaches Nao first. The two women begin to talk, and the conversation inevitably turns to their shared connection: Kirishima.

Nao reveals to Yoshino some of Kirishima's past that Yoshino had no idea about. Meanwhile, Nao faces trouble of her own. Her ex-boyfriend, Ozu, has uncovered secrets about her past and her previous relationship with Kirishima, gaining leverage that could impact her future. With this power, Ozu makes a troubling demand of Nao—one that could change everything.
