Yato ruins everything on purpose, and somehow that's exactly what makes these two episodes work. The OVA doesn't care about plot momentum, it burns time on Hiyori's high school entrance and a cherry blossom picnic that falls apart the second Yato shows up, and in that space you get the character moments the main series never has time for. Watch it between seasons one and two if you want to remember why you liked these people before the story gets serious again.
Hiyori Iki is ready to conquer high school, but the self-proclaimed delivery god Yato has a different vision for her first day. Between his chaotic schemes and refusal to leave her alone, making a good impression becomes an uphill battle. Will she survive the spectacle he creates, or is her high school reputation already doomed before homeroom even starts? In a separate adventure, Hiyori organizes a cherry blossom viewing with her friends on the perfect spring day. The gathering seems peaceful until she makes the mistake of inviting Bishamon, a fierce combat deity with her own complicated history. Things spiral quickly when Yato and Bishamon start drinking together, and their ancient rivalry bubbles to the surface. What should have been a relaxing afternoon transforms into something unpredictable as these warring gods remind everyone why they're feared across the supernatural realm. These two episodes blend slice-of-life moments with sudden bursts of supernatural chaos, capturing the weird friendship between Hiyori and Yato as their worlds collide. The humor comes from watching ordinary situations get turned upside down by the gods around her.
