is it right that there will be new episodes of ইনুয়াসা ? (besides ইনুয়াসা the final act)

Well I don't know about new episodes, but Rumiko Takahashi did do a quick one shot জাপানি কমিকস মাঙ্গা for a charity related to the 2011 earthquake tsunami disaster in Japan. I've never heard anything about it being animated though, since it's only a single chapter. :/

Here enjoy: link

There are movies, if আপনি want. The first one is Affections Touching Across Times, then The দুর্গ Beyond the Looking Glass, Swords of an Honorable Ruler, and আগুন on the Mystic Ireland. I didn't found the 5th movie, sorry :)
