Ashu Tribe

The Ashu Tribe (アシュ族, Ashu Zoku) was apparently an unknown branch along the human evolution line. Each Ashu has a concentration of life force, namely a "soul", which gives it particular fighting abilities. Feared and hunted down as "youkai" (demons) in ancient times due to their feline-gargoyle appearance, they were ultimately sealed within another dimension using the "100-Demon Mirror", only Gai and Hyouga remaining free. According to Mr. Voice, humans seeing the Ashu is what inspired the various monsters in myths. They first appeared in Task 17 to obtain the mirror to release their brethren. However, only Rei was freed before the mirror was shattered to keep the others from entering the human world. Eiji Takaoka, as a member of the Takaoka clan, has been fighting this group even before joining the SGS. After their first defeat at hands of the Boukengers, Arch Priest Gajah uses his power to bind Gai's and Rei's souls to the world long enough to install his Gordom Engines into them. With the Gordom Engines in them, Gai & Rei formed new bodies for themselves and became Questers (クエスター, Kuesutā), robotic-armored versions of themselves. The Questers possessed the ability to create wavelengths with the Gordom Engine, which interfere with the power of the AccelSuits' and GoGo Vehicles' Parallel Engine, and can melt into the ground. The two soon left Gajah and became freelance Treasure hunters, using the Gordom Engine technology and the Precious for their benefit of eliminating the human race, making the Questers the most dangerous of the Negatives. In Task 42, after the Homunculus was destroyed, the Questers challenged the Boukengers to battle, with Gai being defeated by Eiji, while Rei was destroyed by the Dual Crusher, finally destroying the remaining Ashu Tribe on Earth. Eiji would later set up gravemarkers for the Questers out of respect.

Ouga
Ouga (オウガ, Ōga, 40, 42): The king of the western Ashu tribe, sealed long ago with the rest of his tribe. Ouga was sealed within the mountain by Eiji's ancestors until Rei released him. He seeks and intends to eliminate Eiji claiming that his mother, Kei, who Ouga knew since they were young, cannot complete her travel to the other world with Eiji, the living proof of her "sin", still alive. Ouga's Ashu soul is an "Absorbing Soul" which allows him to absorb life from the surrounding life forms to heal his wounds and perform the technique "Hundred Demons Heat Haze Reflection" to create copies of the Boukenger and attack them. After a harsh battle, Ouga enlarges himself and attacks only to be destroyed by DaiTanken's Bouken Flash. Eiji attempted the Ashu Soul Vanishing, but Ouga jumps at Eiji, placing him in an illusion. Posing as Kei, Ouga intended to make Eiji his prisoner, only Eiji wanted to return to his friends. Ouga refused to accept this, discarding his illusion to kill Eiji. But Kei managed to recreate Kando's shakujo for Eiji to use on Ouga, killing him with the Ashu Soul Vanishing technique. His name comes from romanized term for "Ogre." Ouga's design was based on Hyakujuu Sentai Gaoranger's evil version of GaoHunter.
