For those who don't want to be spoiled then Get the fuck out of here!!
And for those who are seeking answers, either you check the novel or continue reading. Now! I will make it simple, the real seventh brave(fake brave) is none other than the Main Character himself, Adlet Mayer. In the first place, their deductions are right. Well that bunny hime is also fake but Adlet is indeed a fake. He was planted by one of the fiend boss to protect Flamie who is a tool of the fiends. Flamie is also the one who killed Adlet's sister. Ok, why am I posting this? Cause the author is one of a hell fuck up person. So many plot twist that will blow your mind and have an endless nosebleed. If you think I'm lying then read the novel! The anime is good but the plot is really really fucked up. It will make you confused and crazy and the story isn't finished yet!!!! More unending plot twist! The next volume release is on feb 2016!
