Masahiro Sagane

After participating to a previous show where they have to bet or be challenged to any kind of competitions, the losing members of the Gaki no Tsukai are selected to spend 24 hours in a setting which they have no knowledge of the theme nor the course of the events. They are exposed to various absurd and crazy situations nonstop for 24 hours and must refrain from laughing. If they do so, hang-men appear and hit the rule breakers with a weapon (the weapon varies every year).

Hanpeita Takeichi, a samurai, finds that he has travelled through time to modern-day Japan. He's taken in by an old man who runs a cram school, and begins to work as a teacher there.

Sakura was once the female star of a television show about a team of superheroes, but retired from acting after its cancelation and got married. One day, she attends a reunion of the show's cast and crew and crosses paths once again with her red-garbed castmate Kotaro, who she had been secretly attracted to.
