Tien's dojo reside next to some mountain town where they mentor 12 students alongside Master Roshi who pays them a visit to assist in their students' guidance. Shortly after an ex-student of the original Crane School, called Yurin, comes to the dojo, pretending she's interested in training under Tien, but really seeking revenge on him for ditching her behind when he and Chiaotzu left their original school. After she manages to take their students under her spell she causes them to be mindless "zombies" and attack the nearby town, Tien asks Goku (who came to invite Roshi and Tien to the Tournament of Power that will be held in 9:40 hours from then) to take him Chiaotzu and Roshi there so they could take care of his havoc causing students. Which they do. After the crisis is over, Tien takes Yurin as his student and agrees to Goku's recruiting request as he believes that if the Team Universe 7 will win, he'd get 10 million Zeni and he opting to use the money to rebuild the town his students harmed.
It can be seen as a precursor to Tien Shinhan's New Crane School.
