Kidnapped by yokai at age eleven, Kotoko Iwanaga gave up one eye and one leg in exchange for becoming the "goddess of wisdom" for spirits. Walking with a cane, she resolves the troubles of the supernatural.
The one Kotoko devotedly loves is Kuro Sakuragawa, a young man who, after eating a certain something, gained immortality and the power to decide the future. The two eventually face a difficult case: Steel Lady Nanase, a spirit born from an online idol made manifest.
Airing from January 2020, produced by Brain's Base. A one-of-a-kind battle of wits that settles cases not with the truth, but with a "plausible fiction" everyone can accept. 🔮
📝 Highlights & Appeal Light spoilers
01① A Mystery Solved by Fiction, Not Truth
Instead of exposing the culprit or the truth, cases are settled by constructing a "plausible lie" everyone can accept — a fresh idea that flips the conventions of brainy showdowns.
02② Kotoko's Overwhelming Verbal Duels
Kotoko's long-speech battles, cornering opponents with vast words and logic, are the biggest draw. You get pulled deeper and deeper into her eloquence.
03③ Kotoko's Relentless, Devoted Love
Firm before monsters yet a full-on lovestruck maiden in front of Kuro, Kotoko's gap is adorable. The blend of mystery and romance is exquisite.
04④ The Secret of Immortal Kuro
Kuro's power to revive no matter how many times he dies, and the true nature hidden behind it, give the story depth. Keep an eye on his other ability, too.
05⑤ Steel Lady Nanase, a Monster Born from the Net
The premise that people's "rumors" and imagination can gain physical form is modern and chilling. The way fiction erodes reality keeps you on edge.
06⑥ An Eerie, Beautiful World of Spirits
A Japanese-flavored, fantastical world where yokai and ghosts simply exist is a big draw. Brain's Base's composed art colors the atmosphere.
07⑦ Intellectual Density to Savor as Dialogue Drama
A dialogue drama that dazzles with words and reasoning rather than action, to be savored slowly. There's joy in engaging your mind with their banter and logical fencing.
08⑧ A Striking Theme Song Sung by Mamoru Miyano
The OP "Mononoke in the Fiction" and ED "Last Dance" brilliantly express the show's eeriness. Mamoru Miyano, who voices Kuro, singing the ED is a stylish touch.
💡 Key Points & Predictions Some spoilers
Ahead, Kotoko and Kuro take on in earnest the difficult case of Steel Lady Nanase, a monster born from online rumors. Because the opponent is a being made manifest by people's imagination, it cannot be defeated by presenting the truth alone. So Kotoko constructs layer upon layer of "plausible fiction" everyone can accept, trying to negate the monster with words and logic alone. Kuro's hidden power and the intentions of his cousin Rikka intertwine, and the battle of wits grows ever more heated. Along with where Kotoko's devoted love leads, you can't look away from this intellectual mystery where fiction and truth intersect. 🔮

Highly recommended for anyone who loves intellectual mysteries that dazzle slowly with dialogue and reasoning over action. The reversed idea of solving cases with "fiction" rather than truth is one of a kind — irresistible for fans of battles of wits.
