I'm starting thinking we won't have more cross events anymore. 2 years and only 2, Garo , still running and a recycled Yo-kai. Seems developers doesn't have any interest on cross events for this game. Aside the eternal delayed FFXV events (and I start doubting if will come some day) there is nothing more planned. And they said this events takes years to make (who knows why, maybe too busy with things in the game to find free time for events).
