A company lost an SD card containing trade secrets, and the office was in a commotion for a while. Temporary worker Ekusuke Inari (played by Masaki Okada) was the first to be suspected. As his name suggests, Ekusuke has encountered countless incredible misfortunes since he was a child. He has not even been able to escape the low-probability event of a meteorite falling. Of course, bad luck has also caused setbacks in his studies and career. In order to prove his innocence, he contacted the strange detective Kyoko Okitegami (played by Yui Aragaki) through the mysterious detective agency manager, Furukawa Kizuna (played by Mitsuhiro Oikawa). Kyoko has silver hair and is covered with notes. She only accepts appointments on the same day, and all cases are guaranteed to be solved on the same day. What's even more strange is that it is said that her memory will automatically clear after she sleeps. With the help of Kyoko, Ekusuke successfully cleared his name, and he had a faint affection for this unique girl. Of course, their fetters will never end here... This film is adapted from the "Forgotten Detective Series" by Nisio Isin.
