It’s exactly like Attack on Titan but with trains and zombies.
Pretty good first episode. From what I recall, the first episode followed the first episode of attack on titan really closely? The main character has a similar personality, the town almost gets wiped out, there’s a wide gap with the ruling class, etc., etc.
Well, at least it doesn’t seem like they’re going to have to go to school where they make friends and shit. I hope.
