Dragon Ball is Akira Toriyama's masterpiece.
It deals with the adventures of a boy named Son Goku, who goes through several situations, but his main objective is the best martial arts fighter in the world.
Summary (with spoilers)
Gohan and Annin would not let Goku turn off the furnace, for the simple reason that spirits would not have access to their afterlife or be able to ever return. Evil spirits would also be trapped and will destroy the Earth.
Suddenly, Annin starts fighting Goku and is no match for him. She grows to a giantess and continues fighting Goku as the fire surrounds the Ox-King, who is trapped in the castle on Fire Mountain. He does not seem to have much time left.
The feathers on Annin's head are like swords and she tries to stab Goku and step on him and blow him into a wall. Annin formulates a plan to fix the furnace after seeing that Goku has the Bansho Fan. They need the shell fragments from a fire eater and the honey from special bees. Luckily, Chi-Chi has both vital requirements on her. With aid of the Bansho Fan and Annin lifting the pot, Goku descends into the furnace and manages to seal the hole, barely making it out alive, and he and Chi-Chi embrace. The flames at the castle have died down and the Ox-King has survived and kept the wedding dress intact. Goku and Chi-Chi proceed with their wedding and finally get married. Chi-Chi is shown hugging Goku, who is at first uncomfortable with it, but then is shown laughing with Chi-Chi.
- It was the last episode of a very important anime.
