Sandar

Sandar is one of five kingdoms on an island of Cierce in the Philippine Sea (along with Storian, Kamolat, Neutronica, and Quesia). The island speaks a dialect of Japanese that is different than that of the mainland and don't use Kanji or Katakana, but an alphabet that is cross between romanized Japanese, as well as German and English called Kangarian.

History
When the Venom Fever hit the island, it came at a period where Sandar's economy was on the brink of collapse. Since Storian and Quesia were abandoned due to how devastating, Sandar grew into the largest of the remaining Kingdoms by over triple that of Kamolat and Neutronica (both have 15k-18k).

The Venom Fever left behind 5 youth, Gakuto; Naoki; Daigo; Chisa and Asheer, with super powers. Four of them were trained to become the Kishi Sentai Sandaranger, without the knowledge that Neutronica had discovered 3 youth of their own (Eltar, Janssen, Tauro; Reagan and Avery's powers are only discovered in series) who were going to become the new Kagarangers.

The Kagarangers crossed paths with a conflict between 4 knights of their kingdom and a force of evil knights. With their help, they were able to find Zharen and defeat Right Hand Turbulence. Naoki had died in the battle and his powers became Asheer's. By the time Reagan and Avery have a son, Daigo has also past (along with all but Janssen of the Kagarangers).
