Chapter 5 Spoilers
Ok guys, Chapter 5 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.
The chapter name is Shield of Scales (鱗の盾). As far as I can tell, we don't get any confirmation about Yuki being the Rabbit Goblin. Teppei vs. Numazawa's fight continues but it doesn't end.
