Reasons I appreciate Serai from Sea of Stars:
I love that the big reveal of her alter ego holds absolutely no narrative weight (at least so far). As I was playing I was like, "Okay, I know 'character with an incredibly obvious but somehow still secret identity' is a common trope, but really how has no one figured this out yet?" And then she admits it and the gang is just like, "Yeah, we figured that out immediately, but we just figured we'd let you pretend to have a secret for as long as you wanted." (I guess the name Captain Klee'shaë should have made it obvious that the writers were going to turn that trope on it's head.)
I also love the weird turn based combat scenario that is Serai's Ultimate. She just casually whips up a portal in the middle of battle, changes into her Captain outfit, parades her crew onto the bloody battlefield, does a little dance with them, then ushers her crew away again while the scene is littered with outlandishly huge cannonballs, all while the boss just chills like two feet away.
