What surprises me is Life Man. It has a real big fanbase from the start and was scouted by the henshuubu while it didn't win the serialization contest.
Maybe because its readers buy digital...
I think the author of War of the adults said that few people bought the manga while the series has the best PVs of all the plateform. It means that people want to read it, want to know what is coming after, but just for free and don't want to buy it as tankobon. A lot are buying it digitally I'm sure, but it's really weird for somebody who has 50k followers....
Followers don't automatically translate to buyers, sure, but what's the origin of the "problem" in these cases? .......
Ichi and Kagura fans are buying tankobon, those fans are not. If tankobon are just 20% of buying, then we can say that less readers are buying even digital? The proportion of tankobon/digital is different by series, but it's like 50/50 at best?
I love anaylizing things, but we lack variables to understand the whole thing....
