Scarlet Soul, Volume 3

After being separated from her companion and held captive, Rin finally broke the enchantment and was able to reunite with Aghyr. Now their only chance at getting answers about the sacred sword lies with the very same wind oracle who trapped RinBuren! Can they trust Buren when he says he's seen Rin's missing sister, Lys? Not only that, but Buren claims Hitaken actually has a sister sword! 

Everything that's happened so far seems to be connected in ways Rin doesn't yet understand, but Aghyr might have a vital clue he's been hiding from Rin all this time...
