Sharp, aren't you?Daring to interfere with my Mapo preparation...How very reckless.Really, Kotomine, stop doing that!However, it's not "oba-san." It's "onee-san!"It is also fine for a mother to say this sort of thing.Sure! Thank you, onee-san!Thank you, oba-san.Are you prepared...?Hn...It would have been better if you had told me you had a friend coming over, Gilgamesh.Allow me to explain. When her children's friends come over to play, a mother prepares juice or something that she doesn't routinely serve, in order to create the impression that "So-and-so's mom is really nice."It's noisy on the second floor for some reason...
