Wow what a chapter, and Irene's story it does remind of actually fairy tales, how ironic. I have seen some scumbag dads in fiction, heck look no further than Minerva's dad, heck Laxus' dad is not exactly father of the year material, but oh man, Erza's dad what a totally scumbag. Suddenly Lucy's dad is not looking so bad. Cana you are so lucky, you don't need even know it.
But now everything makes sense with Irene, the scar of course, and the whole exchange with Fliore.
Irene becoming a dragon for so long, she lost her mind, you have to wonder what role she played in history when she was a dragon.
Well that was an intense chapter, I have to wonder how this fight will end, I see the loop hole for Erza winning, Irene's enchantment took a while to take effect or Erza's has to awaken her power, and she will be an equal match for Irene and she will defeat her. Calling it.
