Rin's caught between two lives that can't coexist, and the OVA doesn't waste time pretending there's an easy answer. The action never stops long enough for you to think, which is exactly the point: when you're living on borrowed time in a city that isn't supposed to want you, moving is the only honest thing left. Zakuro arrives not as a villain but as proof that Rin's old world never really let her go, and that collision between who she was and who she's trying to become hits harder than any supernatural threat ever could. The show flinches at nothing, not at violence, not at the cost of belonging somewhere you don't fit. By the end of three episodes, Rin's ramen shop job stops being a cute detail and becomes the entire point: sometimes survival looks like showing up to work the next morning.

Two years after settling in Sakurashin, Rin Azuma, a Jiang-Shi yokai, has adjusted to city life, spending her days with friends and working at a ramen shop. That calm ends when Zakuro Kurumaki, an old friend of hers, invades the city intending to seize Rin and persuade her to help destroy Sakurashin alongside the other yokai hunters and Enjin Hiizumi, the series' main antagonist. Akina Hiizumi and the rest of the Hiizumi Life Counseling Office take a stand to rescue Rin, tune the yokai that has control of Zakuro, and defend the city. Adapting the manga's Hoshi no Umi arc across three OVA episodes, the story blends supernatural action with comedy.
