Kunikida's entire philosophy gets tested in real time, and watching him choose his ideals over the easier path is quiet and brutal. This OVA doesn't pretend to be more than what it is, a single episode that cares only about whether you understand why he can't compromise. You'll recognize yourself in his logic, and that recognition will hurt.

Members of the Armed Detective Agency debate who would make the best second-in-command. Meanwhile, Doppo Kunikida goes about his official duties, sticking to the schedule written in his diary as he always does. A sudden incident involving a bomb puts his long-held ideals to the test, and he must decide how to act when a single life is weighed against hundreds. This one-episode OVA mixes action, comedy, mystery and supernatural elements. It came bundled with the limited edition of the manga's 13th volume and adapts Chapter 40, a story that falls within the third season's timeline even though its release was tied to the second season.
