*winks* So...What is your snk OTP? ( ͡° ͜ʖ ͡°)
I ship these two countries in Snk:
And the official ship name is Mid-East Allied Forces
Headcanons: The Middle Nation had rich oil resource while the Eastern Nation had advanced technology, yet they were both facing their greatest threat: the Big Bad Marley as he wanted to expand his territory and kept attacking the other countries. The Marleyans bullied those non-Eldians in the internment zones (*coughs* Easterners), thinking they were useless and forced them to leave Marley.
The Middle Nation people rescued them and brought them to the Eastern Nation. And slowly the Middle Nation and the Eastern Nation became close friends (allies), thinking they must work together to deal with Marley, that they developed the Anti-Titan cannons in chapter 91 and other new weapons blah blah blah.
Perhaps in Snk 92 when the fortress soldiers are in danger, a group of air force or the navy will go to stop the Marleyan warriors—-or they do something to turn the tables on the Marleyans and forcing them to retreat.
