It is what you expect from a Fire Emblem plot, but with idols, literally half (all friendly mirages) of the cast has amnesia in the first chapters of the game. There's also a mind control plot. Literally cannot win, everybody needs dumb shit happening to their brains apparently. Combat is entirely dedicated to a combo system that gets boring real fast, and its either too easy or suddenly bosses do all of your health in one hit, so you need to grind until its easy again.
