Have you done Shangri-la and rescued Hornet on that playthrough since they are both required for all the A endings? If that's the case maybe it requires you to have done the toushin mission on a previous playthrough.
edit: just to prove I'm not talking out of my ass I did not do toushin mission on the playthrough that I got from the sky ending.
Yes, I have both Hornet and Shangri-la done. I'm not sure which mission is the Toushin Toshi mission, is it the one where you right a red dragon and a giant robot? That didn't do anything but maybe I did it too late. I read there's a mission where you fight Tropos without Redeye but that mission never showed up.
It appears that I can win through Land after all, I just have to go back and replay turn 11. It turns out that the only way I can get any of the countries to liberate themselves before turn 14 is to drop both reinforcements on that country the turn after I kill the last demon boss. Since I defeated Lexington/ Juno/ Atalanta on turn 10, if I assign both reinforcements to Leazas on turn 11 prep, Leazas wll self-liberate by end of turn 13. Splitting up the reinforcements is a mistake; it actually makes strategic sense that you shouldn't split up your forces and should instead crush your enemy quickly when they are beaten.
So -
Turn 10 - Defeat Lexington/ Juno/ Atalanta
Turn 11 - Reinforce Leazas twice -> Defeat Pi-R
Turn 12 - Defend Free Cities -> Liberate Zeth
Turn 13 - anything -> Liberate Helman, Leazas and Free Cities both liberate themselves
Also my Free Cities 2nd Campaign chests seem to be dropping the same cards which is great since I picked up Nude Hanty, Nude Satella, Freya and Ogrure the 3rd last time on that map.
