There are plenty of anime series out there that appeal to fans of Ghost of Tsushima, as well as the Yakuza franchise, but Attack on Titan is not one of those series. The series takes place in a seemingly dystopian world where the majority of humanity has been wiped out by giant, man-eating humanoid monsters called Titans, and what is left of humanity now lives in a large kingdom surrounded by walls. This is what appears on the surface, and it's not until viewers are done watching the first three seasons that the premise expands to cover a wide range of themes and motifs that have helped cement this show as one of the very best anime ever made.
