Ojii-san

Ojii-san receives little characterization beyond accepting his unexpected place in the football match.

His ordinary appearance and occupation are central to the joke: the desperate team recruits a passing elderly janitor simply because it needs another body on the field.

Ojii-san has no established supernatural abilities or specialized combat skills.

No professional football background is attributed to him. He participates because the team needs to fill its final position.

Daisaku Amarao's retirement match is threatened when most of his teammates become unavailable.

Sakata Gintoki and his companions assemble a replacement squad from friends and acquaintances but remain one person short. Ojii-san is spotted nearby and recruited as the final member.

He subsequently participates in the chaotic match alongside the assortment of Kabukicho residents brought together for Amarao's last game.

Daisaku Amarao is the professional player whose retirement match Ojii-san joins.

Sakata Gintoki and the Yorozuya recruit Ojii-san to fill the team's final vacancy.
