Was already expecting this flashback to mostly keep the full picture of the God Valley incident to the background and not reveal everything since it's been pretty clearly set up as a Kuma centric retelling of events but am not sure I liked how even the little we were given was handled. Feels like things would have been way more impactful and epic if all of these spreads of character reveals and grand entrances were kept for the eventual flashback fully dedicated to depicting the God Valley incident.
The way things are framed here with the constant jumping from one action to the next across the island in a single panel with no sense of time or scale and with each group and individual character pursing goals we don't even fully understand yet leaves me unimpressed and barely invested in what should be one of the most significant events in the lore.
Might be an unpopular opinion but I think keeping the entire thing purely focused on Kuma and co would have been a service to both the future God Valley stuff and this present flashback. Might have at least given us the time to flesh out the context behind Ginny, a random pre-teen who's been a slave since 4, somehow having the technical know-how, equipment and just general smarts to leak information kept top secret by the most powerful organization in the world and precipitating what's probably the largest crisis they've had to face. Without the full story of how the hell she and Iva figured out all that stuff, how long they have been planning it and setting it up and the difficulties they faced, everything legit feels like a lazily written way to make plot progress.
We didn't even get to see Kuma escaping Saturn or even a single panel of him actually depicted saving the other slaves in the middle of the chaos. Those would have been dramatically striking moments to fully visualize but for some reason they got entirely skipped over and we are left having to ourselves mentally picture what were, thus far, the most important actions of the FB's main character...
