Drink and you're invincible!

Monday morning, in a hotel room. A man in a black suit wakes up. However, he himself has no idea where he is or why he is there, and he clutches his head, desperately trying to remember. To calm himself down, he takes a cigarette out of his breast pocket, and along with it, some "purifying salt" falls to the floor. Suddenly, fragments of memories begin to surface one after another in the man's mind. "A funeral...a coffee shop...a bar...yakuza...what!?" Is it a nightmare, or...? This is a comical depiction of an earnest, ordinary salaryman who gets into trouble while drunk and finds himself pursued by the yakuza and the police.
