In/Spectre

In/Spectre is a supernatural mystery-comedy TV anime produced by Brain's Base, directed by Keiji Gotou, and based on the novel series by Kyo Shirodaira. When young Kotoko Iwanaga strikes a pact with the spirit world, she becomes the "Goddess of Wisdom" tasked with mediating between humans and yokai. Partnering with the enigmatic Kurou Sakuragawa, she confronts paranormal cases using elaborate fabrications and razor-sharp logic rather than brute force. Blending mystery, romance, and the supernatural into a uniquely dialogue-driven narrative, this series offers a fresh and captivating take on the detective genre.

In modern Japan, where the supernatural and the mundane quietly coexist, youkai have long needed someone to turn to when conflicts and troubles arise. That someone is Kotoko Iwanaga—a young woman who, at just eleven years old, was spirited away by youkai for two weeks and offered the title of "God of Wisdom," a bridge between the spirit realm and the human world. She accepted without hesitation, though the role came at a steep personal price. Now seventeen and navigating daily life alongside the supernatural, Kotoko finds herself drawn to Kurou Sakuragawa, a 22-year-old university student she encounters by chance. Smitten from the very first meeting, she harbors quiet hopes of building a future with him. Yet the more she learns about Kurou, the more she senses there is something deeply unusual lurking beneath the surface. Together, they begin to step into a world where folklore and reality intertwine in unexpected ways.
