Kenji Tanaka, a 68-year-old widower, has his life meticulously planned out: wake up, tend his bonsai, eat a modest breakfast, complain about the news, and wait for the sweet release of death.

However, Kenji discovers they have a critical weakness: they have to wait in line.

Armed with the patience of a man who has survived rush hour for forty years, the ability to fill out any government form in triplicate, and a surprisingly effective "Disappointed Grandfather" glare, Kenji begins dispatching the Gloom in the most mundane ways imaginable. He defeats the "Gloom of Social Anxiety" by forcing it into a small-talk conversation about the weather. He vanquishes the "Gloom of Despair" by showing it his meticulously organized sock drawer.
