Re: Weekly Young Jump (Seinen Mag by Shueisha)
Seems odd. I subscribe to Young Jump, Nono no No usually ranks around the lower half but it's not last or anything. It usually ranks around the same range as Kokou no Hito. But then again, the TOCs in YJ are much less effectual than in the really competitive magazines like Jump where being near the bottom means you'll get canceled if you stay there for 10 weeks.
I think what's usually at the top is Gantz (which is always first if it's in the magazine), Kingdom, B Kata H Kei, Shin Salaryman Kintarou, Usogui, Deliver Cinderella, and REAL (When it's in the magazine).
I think Zetman is usually around the middle. Though that one has infrequent serialization, too. So does Rozen Maiden. Captain Tsubasa is in that area, too.
But I don't read most series besides Kokou no Hito and Gantz, and ordering subscriptions online end up not showing up until a week after the street release date, sometimes a few days later.
