About the Dragon Ball Z Shonen J Edition Manga Volume 21

Earth's heroes have come out of retirement, and the audience at the Tenka'ichi Budôkai--"Strongest Under the Heavens" martial arts tournament--is about to see what real martial artists can do! While Trunks and Gohan tear up the Junior Division, Videl, the daughter of Earth's "champion" Hercule, prepares to test her newfound kung fu skills (like flying). Meanwhile, the experienced heroes prepare for their turn to fight Goku, who has come back from the dead just for this one match! But Goku isn't the only otherworldly visitor. Two mysterious contestants have entered the tournament, wielding the power of the heavens...and they have a special mission in this world!
