One night during their honeymoon on the 22nd Floor of Aincrad, when Kirito and Asuna were going to bed, the girl noticed that Kirito did not brush his teeth before sleeping. Although Kirito said that there was no need to brush his teeth in Aincrad and even wondered if it was possible to get a tooth brush in the game, he quickly promised to brush his teeth three times a day after Asuna warned him that she would not kiss anyone who does not brush his teeth. While brushing his teeth, Kirito noticed that his avatar did not have the wisdom tooth that his real body had. Asuna remarked that she did not have any wisdom teeth in the real world, thus she was more evolved than him. After shouting that he was just a primitive barbarian, Kirito sealed Asuna's mouth with his own.
