The "proper" translation comes out on Tuesday nights, 5pm PST, hosted by Kodansha via Crunchyroll.. Mangastream's version is an illegal fan translation, just as much as this one by Yonkou Productions is. The only reason he posted this chapter was to spite everyone who hates on him for FT spoilers. So instead of spoilers, he posted the entire chapter. And rightfully so.
