Although Hyouma Kunato has begun to feel comfortable around Botan Nagatsuki and her family of tsukumogami—objects possessed by spirits called marebito—he has not forgotten about his main goal in life: revenge. Unbeknownst to Hyouma, while he is training in Kyoto under the supervision of the Kadomori family, the Bureau of Traditional Music, a group of three musical instrument tsukumogami, begins to enact its plan. The trio questions Botan's family about their intentions regarding Hyouma's presence near the person embodying the frontier between the human and marebito worlds. Soon after, the paper umbrella tsukumogami that Hyouma had been pursuing for years suddenly reappears and abducts Botan along with her university friends. Rushing to save the one he swore to protect, Hyouma might have to change his priorities if he wants to keep his promise to Botan.

Ever since he published a picture that sparked a wave of online harassment, freelance photographer Kouya Madoka has lost everything: his wife Saeko Yukihira, his confidence, and his courage to photograph people. However, years later, a job offer introduces him to the exhilarating world of Formula 4 (F4). A single fierce battle between the amateur drivers in the junior category of open-wheel car racing becomes enough to make Madoka unable to put his camera down. When Komaki Motors' Haruka Asahina bursts into tears on the track, Madoka manages to capture this vulnerable moment. This photo eventually leads Madoka to an impulsive decision: he will help sponsor both the Komaki team and Haruka himself. But the unreasonable costs of the sport quickly cause Madoka to reassess his ambitions, and he seeks different ways to support the severely underfunded F4 team. Despite the uphill battle, Madoka's determination for Haruka to succeed may be the trigger that can propel the young driver straight to the top.
