The couple are well known for having rather vulgar and obnoxious attitudes; constantly deriding monster girls, especially Kimihito's house guests, as freaks, or other derogatory remarks that border on cruel. Their vulgarity is apparent especially after Kimihito and Miia encountered them in a love hotel, which they were in to hide from people taking unauthorized photographs, and began clamoring whether or not Miia had the proper organs for intercourse.

The male is noted to be even more malicious than the female as he appeared in a chapter without the female and instead a group which appeared to be a gang, with the intent to violate Centorea(however in the anime, the female was with him). However, like in many of their appearances, he received his comeuppance. This is shown when Kimihito knocked him and his girlfriend out for harrassing Miia and Rachnera tying up and frightening them to the point of unconsciousness(in the anime, the female was tied up with the rest of the gang).
