Thanks for answering my questions. Now I have a few more.
Do you mean Naraku would try to bring Inu no Taisho back like he did the Band of Seven and control him, but the controlling wouldn't work because he's too powerful?
And wouldn't Naraku need his remains for that to work at all? So wouldn't he not be able to even do that? I mean the Taisho had his remains put in a black pearl and hidden for a reason. Naraku wouldn't know about the pearl...but then again Inuyasha knows after getting the sword, and I can imagine some scheme involving Naraku and Kikyou and using her to get that info from Inuyasha. But he would likely still be back because of a jewel shard or shards, so he wouldn't really be alive, not even flesh and bone.
So my last question or questions.
-Is Inu no Taisho brought back temporarily or permanently? And is there a reason for him being brought back permanently?
