I bought this because the FBI characters are my favorites, haha.
This edition is a great complement to Volumes 42 (Vermouth Reveal) and 58 (Kir Showdown)!
You get Jodie's debut (at the Arcade), Akai's debut (the Bus Hijacking), which have important foreshadowing for the Vermouth Reveal in Volume 42.
There's the 2 "FBI vs Black Org" chapters, but not the Kir debut that leads into them, so it kinda feels like you're jumping into this case in the middle of events... which you technically are.
After that, there's the case where Camel becomes a suspect in a case, while Akai gets called by Kir to meet at Raira Pass. This is a great complement to Volume 58, which kinda leaves you hanging in the middle of this case.
There's Subaru's debut and the case with Scar!Akai at the Shopping Center, both cases being important foreshadowing for Volumes 72 and 85.
And you finish on the "Sera meets Heiji" case, for whatever reason! (though I'm not complaining)
Overall, a very worthwhile collection of cases, with only that little downside on the Kir debut.
