I used to love Fairy Tail but now I just want to see the end, it was the same with Naruto. The plot is just getting poor.
So instead of Wendy getting seriously injured because of Irene catching her off-guard, Hiro decided to make a rushed chapter of body-switching just to K.O. Wendy?
I think Irene will lose in a few chapters, meanwhile she's extremely strong. Or maybe she will become an ally, just like some other characters. I just doubt she'd die, since in this manga hardly anyone dies.
I just get this disappointment-like feeling that most of the times they defeat an opponent, they just fall into unconciousness so they can come back as a "plot-device". Or even if they die they are brought back to to life to fight again. Kind of slows the plot down, and I get confused who's yet to be fought.
