I'm a librarian who loves anime, manga, and reading a wide variety of genres.
This volume was decent, but the switch to the training flashback went on a bit too long and was a little disappointing after the awesome “ humanity won its very first victory” moment. However, the sudden shift from smiling trainee Marco to dead Marco was jarring and brilliant. So horrible and sad. So many people died for that one small victory.
This is practically a given at this point, but I continue to dislike Isayama's artwork. His scribbly linework manages to make every single scene look dark, even the ones that are supposed to be funny. This was most noticeable during the training flashback, when everyone was relatively safe and occasionally able to laugh and joke.
