Not that I actually expect anyone to see this post since the campaign ended, but there is a new Anime series with some interesting similarities to our setting.
There isn’t much info out on the series but it just started airing. Its called GATE.
The basic premise is that a portal opens in Japan and a fantasy army attacks. They have various monsters, dragon-riders, and your standard medieval soldiers.
They kill a bunch of civilians before the SDF shows up and slaughters them with firearms.
Then rather than risk destroying the Gate and having a new one appear they secure it and send an invading army.
It has potential so I figured I would share.
