Exallion
Its a split personality but one who has abilities that should not be possible along with knowledge that should not be known. Maybe this part of him was nudging him towards making a journal about the zombie apocalypse because he knew it was coming. Then again there also seem to be mutant beasts which I cant wait to see more of so maybe it would have been better to focus on other supernatural apocalypse type novels not just the zombie apocalypse ones. Regardless I do look forward to reading more of this story.
Thanks you for the chapter ! Oooooh ! I have not see this coming ! It's awsome !!! It isn't a breakthrough, it's even better ! Well now we know Marck have still a lot to learn about how utilising his power. But dam this personnality is so cool >.< Personnaly I vote yes for enslaving the mutant and make her dress with a maid outfit ! (I'm just joking buuut... xD)
