"Aincrad Arc" technically is only 1 book long, and both Fairy Dance and Phantom Bullet are 2 books each, while Alicization runs for 6, leaving 3 books "Arc-less". There's an inconsistency there. For the anime episodes I can see it being rationalized, because they're forced into chronology, but that's not a great idea.

Overall, I think we should get rid of the Arc Categories in general, and find a suitable replacement(s) for them.
