Sometimes I wonder why Neutronian thought the way he made one of his fictional nations was cringey. Now I know. It doesn't accurately depict it's namesake game or series or something in any way.
Read manga, it was fully translated, sums up all pairings pretty good(Kaede and Yuzu are my favorites).
No doubt there will be no season two. Only OVA, or may be movie. Minimum chance.
