Ninjanime said:I only know that S4 covers two volumes and we have 5 volumes that haven't been adapted to work with. Surely they'll catch up to the light novels after this season. But is the next story arc long or short?
S4 covered three volumes, 12-14. S5's arc would cover 16-18 (volume 15 will likely be skipped, but it's not a problem because it's just short stories from the past). In other words, we'd be one light novel behind, so season 6 would probably come several years later.
Personally I was rather hoping an Aedes Vesta or Argonaut adaptation for the time being and delaying season 5 a little for pacing, but I'm still excited.
