P4 …Dreaming Souls Truth Extra
The Japanese name is Bessatsu Jijitsu Mukon 別冊事実夢魂. While "Mukon" is written as "Souls of Dreaming People" (<- Dreaming Souls), if it's written in different Kanji, the word can also mean "without proof", making the name of this magazine sound like "Truth Without Proof"

P2 …interesting for a third-rate magazine
The term she actually uses is a "third-rate Kasutori-magazine". Kasutori actually refers to shôchû made from sake-lees (Kasu) instead of rice or sweet potato. It was used in the early showa era to also refer to magazines that usually talked about red-light-district stuff and had little success, often being stopped after only a few issues.
