S1.E8 ∙ Hirameki no kyujitsu

Doraemon and friends trying to save a boy name Kukuru and his tribe from Gigazombie who want to change history for his own sake in the ancient times.

Summer vacation is drawing to an end. When Suguru wins a free trip to Okinawa, all of the five students of Asahigaoka branch school are excited to end their vacation with a bang. Along with Hikage, Konomi, and their teacher and the candy store owner, everyone goes to Okinawa for a fun three-day trip. There, Natsumi makes friends with Aoi, the girl who helps out at the hotel they stay in.

Five kids go on amazing adventures through the universe after they rescue an injured alien.

Tianjin, a boy from the city, has to move to his father on the prairie of Tibet. There he meets a golden dog that helps him cope with the new challenges ahead.

Prince Susano's mother dies; when his father tells him she has gone to another place, he sets off in search of her. He builds a boat and goes to see, first, his brother, in his crystal palace in the land of night (where he causes much damage to the palace, but his brother still gives him a magic ice crystal). Next, he fights the fire god, who gives him a magic bird after Susano defeats him, with help from the magic crystal and his little rabbit sidekick. Susano also picks up another traveling companion, a large but dim villager. Next, he goes to his sister, in the land of light. As with his brother, though, he causes much unintentional damage; his sister, who also happens to be the sun, goes off to hide in a cave. The frantic villagers stage a party (in the original legend, an orgy) outside the cave and trick her into coming outside again. Finally, Susano finds a little princess whose land is being threatened by an 8-headed dragon. With the help of a flying horse (who we later learn was sent by his sister) and his sidekicks, they get the dragon a bit drunk and take out one head at a time (mostly, though two of the last three take each other out).

After her village is destroyed and all its residents slaughtered by the evil wizard Gardein and his master The Dark Lord, a warrior known as Lemnear, The Silver Champion, vows to find and kill them both to avenge the massacre.
