Awesome and thank you for your interest in the Resistance. My apology for taking so long, but work and driving 2 hours took quite a bite in my planning. I have looked over your character and I got to say it looks quite impressive of what you wrote down so far. However, there is a problem that Yamatai doesn't allow mercenaries in their space, the only way to get in Yamatai space is either by Exchange program that the Nep has with Yamatai or as a civilian (without guns).
My humble advice, in this case, would be to write down in the history section that you took a holiday and that Hanako's world is the spot to be for a good vacation. Yet shit hit the fan when Kuv invades the world.
