Cute, but at this point, there are so many girls it's just hard to remember them all. it's the downfall of character-based Gacha games. After a certain point, there's just too many to keep track of and it becomes work to remember them all rather than play.
Especially when you have to sort them into squads to battle or whatnot, the mental load is exhausting, sometimes more than your real job, which my end up being more fun by that point.
Edit: I'm not just talking about Azur Lane (although this was one of the reasons I quit) I'm talking about ALL the gacha games with too many characters, which is unfortunately most of them nowadays. Genshin Impact also being an offender, for instance.
