Synopsis

 * 1) Members of the Ka Demon Tribe, Kinka and Ginka are destined to battle each other until one kills the other, consuming his power in the process.
 * 2) They are met by the half-demon princesses, where they steal Towa and Setsuna's Rainbow Pearls.
 * 3) Kinka and Ginka are attacked by Joka, the leader of the Ka Demon Tribe, who intends to take the Rainbow Pearls for herself.

Summary
The demon twin brothers Kinka and Ginka who share the same body continue their battle to the death so that the victor can claim it for himself. Towa, Setsuna, and Moroha are sent to stop the damage they are causing to nearby villages and attack them. Noticing that both Towa and Setsuna carry Rainbow Pearls, Kinka and Ginka hold a truce so that they can steal them for themselves. The two possess Towa and Setsuna's bodies respectively, forcing them to fight each other until Setsuna uses some poison to expel them, but they end up running away with the pearls. The brothers report their feat to Joka, their clan's leader, who decides to absorb both while claiming the pearls for herself.

Towa and Setsuna arrive to retrieve their Pearls when Setsuna, watching the brothers in peril, has some glimpses of the day when she got separated from her own twin sister. After Joka separates Kinka from his brother to absorb him first, Ginka joins forces with Setsuna to defeat her, but Kinka does not survive the attack, with his brother dying soon after. Towa and Setsuna regain their Rainbow Pearls and Towa wonders if Setsuna remembered her past a little, while Moroha laments that because they had their bodies turned to ashes, they can't claim any reward for slaying them.
