Sousuke Kaburaya, a private investigator struggling to keep his business afloat, is abruptly confronted when Sara da Odin—an imperial princess from a realm beyond the veil—plummets through a shimmering portal onto his doorstep. Ignorant of how outlandish she appears in this world devoid of sorcery, Sara unleashes potent enchantments publicly, sparking chaos and compelling Sousuke to escort her back to his apartment. Using the internet, manga, and everyday Japanese technology, Sara acclimates to life in Japan, eventually taking on the role of Sousuke"s aide.
At the same time, Livia de Udis, Sara"s personal knight, also breaches the portal but emerges elsewhere. There she encounters a street‑wise homeless man who embraces her extraordinary origin and eccentricities. Though displaced from her aristocratic roots, Livia swiftly adapts to a life on the streets, a stark contrast to her former status.
Despite their divergent circumstances, both Sara and Livia"s optimistic, determined spirits resonate with those around them, exposing the highs and lows of contemporary Japan.
