If they'd paid attention, they would've caught the fact that they explicitly state it's almost one-of-a-kind due to its current rarity. I've seen people question why Akatsuki changed her appearance to look like a little girl's after she starts moping that her looks are getting in the way of her romantic interest, even though it's stated in both the light novel and anime, in no uncertain terms, that it's how she looks in real life.
