I have read the first 3 volumes of this.
Honestly, I have mixed feelings on this manga serious. InuYasha is one of my favorite mangas/ animes and its the hole reason that I love anime/ manga to this very day. It was my first.
So, seeing a continuation of the story was worrying to say the least. After the nightmare that which is Baruto, I didn't have high hopes for Yahshime. While it's not as bad as Baruto (which isn't hard to do) it had a lot of problems. I have never been so confused before, on what was happening in a manga. Like why is InuYaha and Kagome missing? Why doesn't Sesshoumaru just help his daughters? Why are there more jewels? HOW IS IT THAT THE ONLY CHARACTER THAT DOSENT AGE IS SHIPPO!!?? Everyone else looks like they aged a little bit, but not Shippo. And why...... just WHY did Rin and Sesshoumaru get together!!!!!! He raised her!! Out of any character who would not have a significant other or want for that matter, would be Sesshoumaru. Thats just sick!!!! I didn't need to see that he would groom to her!! But here we are! This was a bizarre choice, and it feels so out of character for him.
The world also doesn't make a lot of sense. The changed how half demons work and how they are blood thirsty, when last I checked InuYahsa himself was never like that unless he was horrible injured. But that's not the case for the main characters. It just feels like a slap to the face to anyone who loved InuYasha. This was not the world that Rumiko made. I know someone else is in the writer's seat for this, but it just feels wrong to me. The hole plot of the 3 kids going off to find InuYahsa, Kagome, Rin and Sesshoumaru is weird and doesn't make any since to me. Nothing is ever really explained.
The thing I like about this is that I get to see old characters again, kind of.
The art is amazing. I like everyone's updated look for the most part. I'm still a little torn on whether I like these new characters. I don't have much to go on with them. Bearly any back story or any story to them. Still mad that they didn't aged up Shippo. Like really, out of any character to NOT aged up they picked Shippo?!
I guess my overall thoughts is that it could have been a lot worse. I just wished I knew what was going on. I like how InuYahsa (the show) was strait forward on where the story was going to go, but still leavening some things a mystery. But this, is a mess. I have no idea what or why of anything in this story. All I know it that they have to find the parents. Thats it. .... I dont know why Songo, Moroku, or any of other friends don't go looking for them. Why wait until their kids to become of age. This to me doesn't make a whole lot of sense.
I'll keep reading and watching the serious to see what they do, but I am still extremely worried that they will ruin it and make InuYasha (as a show) look bad. I just hope they can pick this up and fix it. The last thing I want is for them is to ruin more characters. My poor Sesshoumaru, why did they do this to you. =(
