So... this entire series will be about this guy chasing some childhood friend/class rep kind of vanilla character (if she even is real and not implanted memories), this so called "Aki", as hot women throw themselves at him as he acts all edgy and shit in his pursuit of reuniting with "Aki"...
And is then probably backstabbed by "Agnes", taking all the powers he's taken with the chains, because they were actually her powers originally, and just had to use him since she probably had restrictions in place for her to use it. I am just amazed in how he's immediately come to terms with his surroundings, where he is, and even the hot woman trying to bang him had horns and wings.
He's like an automaton that has now just one driving goal of reuniting with "Aki" and is now immediately a badass. Author, is this "Yuya" actually Tatsuya? Is this guy some alternate Shiba Tatsuya?
