unfortunately there is no inuyasha episode 168...the final episode of the anime is 167 "The Bond Between Them, Use the Sacred Jewel Shard! (Part 2)" the anime series ended because it caught up to the manga and the they didn't wanna create a season or 2 of filler episodes to let the manga get further ahead. there was a 30 min inuyasha short (or OVA) called "Black Tessaiga" that's was shown at an exhibit called “Its A Rumic World” which was an exhibit to congratulate Rumiko Takahashi (creator of inuyasha) for her 30th anniversary of creating manga's. the event was held from July 30th to August 11th of 2008 but as of now it the short is just in japan and there is no info on whether VIZ media will release it in English. according to "hellosoushi1234" (of yahoo answers) in the magazine "anime insider" (issue number 60, released in September 2008) it says that they will be making a new season of inuyasha in 2009 (japan) meaning we should get it in 2010 maybe (US/Canada)........i understand that the return of the anime is a while away and if you don't want to wait you could always read the manga (ill leave the links)........i am a huge inuyasha fan and am thrilled that they will continue the anime =)
