Chapter 8 Spoilers.
Ok guys, Chapter 8 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... chapter 8 is here and chapter 6 is still nowhere to be seen... Anyway, I'm not too sure about chapter 8's name but I think it is "Defeated Soldiers", going to confirm the name with someone who is a professional with Japanese. So with so many chapters that I still haven't read in English, I'm sort of losing the thread of what is going but I still know what is generally happening. Teppei and others reach a military safe place where he finds out that Yamatoyama Base of Yamatoyama City has fallen at the hands of goblins, who now have firearms. So now the soldiers, Teppei and Yuki are going to reclaim the base. Also, Teppei is told in the end that Tsubasa is in the base.
