Yeah, I'm really not too impressed with our protagonists here. They are in possession of something they
know is going to make governments all over the globe sit up and take notice. Something that wars could easily be fought over. Something that the big nations are going to be mobilizing their top tier espionage assets for.
This is serious shit, and they may have outfoxed some low-level flunkies before, they should now realize that they are stepping into a whole different level. Maybe--just maybe--two wannabe adventurers might not be prepared for the massed forces of the world's powers. Whole organizations that are specialized in doing what it takes to get the dirty deeds done without being caught.
They already have contacts in other departments. Perhaps they should have done an end run around fish-face and double-checked things, considering that trillions of yen are potentially at stake? Much better that they deal with the Japanese government in some form, since they have done so in the past, even at a couple of orders of magnitude less money offered than sticking out their necks in the middle of a bunch of neck-cutting enthusiasts.
I realize that our twenty-something protagonists are both fairly superhuman by now, so they may be feeling a little cocky. But setting aside that the other governments all have their own superhumans, and guns, and bombs, and poisons, and other forms of death, there are other ways that they are vulnerable--hostages. People in their families, friends, acquaintances, busloads of schoolchildren. And that is just what I can think of off the top of my head. How many other ways would a ruthless espionage agency have of making you do exactly what they want? I don't know, and I guarantee our protagonists don't know, but the agencies all know and are very practiced in these kinds of situations.
Little did we know that the skill orb was actually an
Idiot Ball in disguise!
