Anyone else confused about how wild rose couldn't kill the speed type black snake guy? That person said that they sent both of them even though wild rose wanted to kill him because she wasn't able to. However he is slower than the main character so he was probably only intermediate level, while the rose girl could still affect the main chracter who is advanced level so much with her ability. Not to mention shouldn't the fact the main character has a fully 100% unlocked brain help with mental effect resistance?
