Gunko not proceeding to take down half of the SH crew (even though she can) but decides to stick to the plan of kidnapping a fodder kid and just dip away. There we have the forced plot again
SH are always nigh invulnerable especially the weaker ones, not even Imu would touch them, nobody ever targets the main cast of the show..
That's the key to stakes killing moment. It's the side character (that we really never cares) that has always been the target for villains
Same formula over and over. That's the main diff between pre-skip and post skip
