GATE: Jieitai Kanochi nite, Kaku Tatakaeri

[KrayZ33]

Except staying away from the land that took everything from her.

Imagine getting kidnapped and taken to a foreign country. Then being abused as a POW there. Not having family in your home country won't make you wanna stay and work at the offending nation.

She lived her whole life in Japan. That by itself normally gives her enough reason to return. What's odd is why she's still on the other side of the gate even now.

She's not working at the offending nation, she's working in a different world... she has nothing to do with the empire.
And there is also the case of people not wanting to see their "pasts" (or whatever) when something is missing, just like people don't want to keep pictures of their ex-es because it reminds them of that time.

Hahahaha, no it didn't. What a reductionist way of looking at it.
I went to American public schools and I know better than that. That's not even close.

Well, the casus belli was the assassination (or the dismissal of the absurd ultimatum that resulted from it), I don't see a problem there. Whether the people acutally gave a fuck about Franz doesn't matter, it's enough of a reason to get allies and politics involved.
