Ok guys, Chapter 7 RAW is out but remember that we are not adding anything of into the wiki until it is released in English. That's why I'm adding it here so read at your own risk.
Well... still waiting for chapter 6 translations... Anyway, chapter 7's name is "The Third". I gotta say that by just looking at the raws I barely understood anything, but I'm fairly sure its about Teppei and Yuki helping the normal people to escape the place they are at and head towards Yamatoyama City.
