It would be interesting if instead of kidnapping the girl their actually hijacked the plane to find Ijin of something he did when he was still a merc but they don't know how he looks like but heard or someone tipped them off to the organization who hijacked the plane to kidnap him and it would be more interesting if Ijin was forced to reveal everyone that he was a merc by quietly or quickly getting into a fight with a hijacker revealing that his not some high schooler but actually has randomly some impressive takedown or shooting and if they connect the dots then they might realize he might been a soldier or a merc or maybe the organization was actually the planning of 003 cause she heard rumors that 001 might be on the plane or not (don't take this text seriously I just making my imagination run wild on what will happen in the next chapter)
