The past arc finally gives you what the series has been building toward: Nanami and Tomoe's actual beginning, before she fell in love with him. Watching them collide as near-strangers, neither one ready to need the other, rewrites every scene you've already seen. The OVA stops pretending the romance is secondary and makes it the entire point.
Nanami's peaceful life at the shrine gets turned upside down when Tomoe reveals a secret from his past. Years before meeting her, the white fox demon lived as a wild, untamed creature until a mysterious woman changed everything about him. Now, strange circumstances pull Nanami into a journey through memories and supernatural events that challenge everything she thinks she knows about her closest companion. As the story unfolds across four episodes, the reasons behind Tomoe's transformation become clear, and his connection to this woman from long ago resurfaces in ways neither of them expected. Nanami must confront uncomfortable truths while navigating her own feelings, all while supernatural forces complicate matters further. The OVA balances genuine humor with heartfelt moments, diving deeper into Tomoe's character than the main series allows. It's a story about understanding the people you care about, about the past's grip on the present, and about what it really means to change for someone. Fans of character-focused supernatural romance will find plenty to appreciate here.
