Episode 10 (Hanyō no Yashahime)

"The Gold and Silver Rainbow Pearls" is the tenth episode of Hanyō no Yashahime.

Synopsis
Conjoined demon twins Kinka and Ginka (from " The Great Holy Demon Spirit's Test") continue their fight for consuming the other and evolving into an even stronger demon. Once Towa, Setsuna and Moroha show up, they take possession of the Gold and Silver Pearls within the right and left eyes of the half-demon twins, forcing them to fight one another again. Meanwhile, a powerful female demon makes her appearance, stating that she can finally get her revenge on Sesshōmaru.

Summary
The youkai 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 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 beacuse the enemies had their bodies turned to ashes, they can't claim any reward for slaying them.
