Every tournament contender is training hard, especially the Z Fighters. Gohan takes it upon himself to train Goten, but some surprises await. For one, Goten suddenly transforms into a Super Saiyan, and he says it isn’t for the first time. He says it just happened one day while training with Chi-Chi. On the other hand, Goten is lacking one very important skill – he doesn’t know how to fly. All of this gives Gohan quite a headache. It only gets worse when Chi-Chi and Videl come face-to-face.
