Oh, it was indeed stated, I didn't catch/remember that because the talk after that was so confusing to me and I guess it took priority in my mind.I mean, it's Echidna's library. Beako is contracted to guard the library. Who else would it be?
I have no idea why Subaru has to "love" Beako or if that's even what she was talking about. What?
And Subaru's reaction was weird too, I have no idea how he came to the conclusion that Echidna is her contractor.
What gave that away? Did Echidna mention the book during the tea party? Was it Roswal who said that?
Jeez, this show is not really benefitting from the 1 week gap at all, especially when the important bits are basically 4 weeks apart.
And as Darth mentioned already, it's so weird that he never brings up the sentence he's supposed to say. Isn't that the only reason why he came to the libary? To make her his ally?
