This was found on the comment area of /g/632037/93f2a2ff88/. The cover pages are also missing like [Tsuya Tsuya] Tatoeba Haha Ga Extra Black (/g/646911/2299c8c758/). I added the cover page from the cover page pictures found on the internet. Hopefully, a better version would show up.

Extra Red and Extra Black are short stories, which were not included in the 6 volume series. They are not Vol. 7 and Vol. 8. Some of the stories were published as doujinshi. These two volumes (Red first, Black later) are the collections of these stories. It's like a celebration of the 10 year anniversary of publication of the first story of the series.
