The Old One.

Fukutaro, the former president of a board game company, continues to show up at work even after handing over his position to his son-in-law. Fukutaro grabs anyone he can to repeatedly brag about the same past exploits, which irritates those around him. Triggered by an event, his daughter finally unleashes her unspoken true feelings about his toxic old-age behavior. Although Fukutaro seems sad and apologetic, he secretly plots a counterattack with his five elderly fellows.
