User blog comment:Juanito316/Owari no Seraph Story Arcs/@comment-25942629-20150212021610

I was wondering what that page was for. Lol. Seraph is more complex than either World Trigger or My Hero Academia, so it doesn't divide up as easily. It flows more smoothly like a novel rather than following an arc-after-arc kind of storyline. Here's an attempt to sort them. Adjust titles as needed. Let me know if you need help with anything.

Why Humans Suck Arc - Chapters 15-18

Training Arc - Chapters 19-21

I don't think this one can fit into any arc so easily - Chapter 22

Nagoya Arc - Chapters 23-30 (and ongoing)
