Sa-do 2026: New Character “Mushi-kun” and Masaki Hashimoto
“Mushi-kun” is a professional soccer player who struggles with never having experienced a proper sauna session.
The story begins when Atsuro Nakata (played by Taizo Harada) and Guanjou (played by Hiroki Miyake) meet Mushi-kun at their regular spot, “Sauna Hoku.” The three hit it off immediately and chat in the dining area, but it seems Nakata and Mushi-kun have been troubled by something recently—and the story unfolds from there.
As “Sa-do” enters its eighth year, a new member joins the group, and this installment depicts the down-to-earth, everyday lives of these three very different individuals.
