@jackmiaw Well, it all depends on the person. I mean, way back when in WWII, the (ongoing) Korean War, and the Vietnam war, a lot of guys in their late teens and twenties voluntarily enlisted.
It depends on the mindset of the person of course. Our MC's mindset here is that there's already other people with powers down there who answered the call and now she's being tossed in. Why not just let those folk take care of things? It's the most logical thing to do, and she took that position. So yes, I do agree with you but I also can't fault people who go run off their hero fantasies in other isekai stories. It's their mindset (no matter how dumb they are).
Of course, to pull something like what you want you'd need to have a good head on your shoulders to think carefully of what you're going to do, in order for the world not to drag you into the call...at least until the point you're just so powerful the world just can't risk dragging you into the call.
@Treswimming Siding with royalty is never idea. Once you offer yourself up into the world of aristocracy, you're now tangled in the mire of cloak and dagger, along with all the political intrigue. Being a vagabond is a better way of thinking, or attaching yourself to some sort of mercenary force at first, then go vagabond. Once you've gotten enough power, you can finally settle down and live life.
