Brief Story Line
In Japan, there was an old secret organization called Zenketsu (translated to English as All-domain Anomaly Resolution Office/AARO) where it focused on investigating mysterious cases. Its Deputy Chief Miyabi Okitama (Tatsuya Fujiwara - School Police TV series, Memoirs of a Murderer etc) was their lead investigator with amazing deduction ability and vast knowledge on historic supernatural stuff. To assist them, Koyume Ameno (Alice Hirose - Bubble, 366 Days TV series etc) from PR Dept of Metropolitan PD was assigned to AARO even though she had no prior experience in investigations.
