I like that Ei's story quest is a date. She's so adorkably cute. Not quite a fan that her special cutscene was her just beating up a random NPC (I wish that were me instead lol). But it really did show her cuter side and she does indeed get lonely no matter how much she denies it.
Also, I am proud to part of the Raiden-havers club as well. I also got Sara but after finishing the story, I think I have to get Yae now for the shipping.
