Utter Betrayal
Right at the doorstep of the Realm Divide the Satsuma decided to switch allegiances, after i helped them to consolidate their Holdings against the Tosa and Saga, now i am sandwiched between 2 shogunate Factions right as i was trying to get my economy up since the early game was me rushing to Khietai recruitment and then swarming the maps with them.
The next few turns will be a Bloodbath.
