* LesYay: Between Ushimaru and Inomata. The two are best friends (despite also being love rivals) and call each other on a FirstNameBasis. In chapter 34, an excited Ushimaru said that she "likes Maria-chan (Inommata) the best" while hugging the latter. When the two had their first "outing" together, Inomata was behaving in a nervous excitement as though she's on a date. In fact, the manga-ka apparently felt the need to affirm that the two were "just normal friends".
