The scene with Blue Rose is crazy. I get it though, and could never do the same. Lakyus would have absolutely stayed and just died, and they refused to let that happen. They were wilding, Lakyus has full right to be pissed, but they succeeded in saving their friend.
The fact that they had to beat the heck out of her, hit her with 5 poisons, and reduce her resistance to magic just to have a CHANCE of the charm spell working on her is crazy. And that was without her gear. Lakyus is just built different.
