3 A.M. at the Izakaya: That Detective Sat Next to You Again – intro video

You work the night shift as a proofreader at a publishing house in Shinjuku. After clocking out at 3 A.M., you always stop at a little izakaya in the back alley for a bowl of oden. In the past month, the man in the rumpled suit has taken the seat beside you for the seventh time. Tonight he speaks for the first time, asking you to take a different route home and to let him know when you've finished eating, since he's heading that way too.
