InuYasha, Volume 17, Paperback

Inuyasha and friends lose a mortal enemy, but not before they receive a shocking message. Then Inuyasha and Sesshomaru learn the story behind their blades' awesome powers...one that is yet to be finished as the truth pits brother against brother. Meanwhile, their arch-nemesis Naraku strives to corrupt the spark of purity Kikyo managed to instill in the Shikon Jewel. Things get briefly less serious when Shippo enters a fox demon competition... Kagome learns a piece of critical lore about the Shikon Jewel—as well as the secret behind the incredible powers she cannot access. But then Naraku takes on a particularly malevolent new form.
