I sincerely had to ponder this one I was like
"Kurohi is gearing towards 24 chapters, about 60 pages max each.... so maybe a 24-episode anime? Since they're kinda long and can be spaced out with filler scenes. Oh but all the backstories...! Hm. about 24 episodes, and maybe like 2 OVAs, maybe 3 drama CDs, and either a movie or a 10-episode spinoff series"
and then Shieldheart was like "....? //shrugs Maybe 22-episode anime with lots of shenanigans not in the original material, but works in with the story."
