Quoting our Spoiler Policy:
Until a manga chapter is released by the official distributor Crunchyroll the 8th of each month at 5:00 p.m. PDT, that chapter's information is considered to be a spoiler. Until the official English version is released, it is simply forbidden to add any information from it (including the chapter's title), and the edits should be reverted on sight. The person who adds spoiling information will be warned about it only once. The information, as insignificant it might seem, might ruin the fun of reading a just-released chapter for some.
So respect the rest of the fans and avoid any edit/comment/whatever related to the yet unreleased chapter until the official translation is out.
