User blog comment:Maki Kuronami/Lesson 6: Aura and the Grim diversity/@comment-7622429-20130823001608

So,the line from the opening sequence,"Victory is in a simple soul",now holds even more significance now that the episode has been released. Perhaps individuals like Crimson have a sort of "corrupted aura"? Only time will tell. Also,I was quite surprised that fight with the Grim Serpent became so violent,seeing as how Lie Ren LITERALLY blew that thing's mind!
