Machine-Doll wa Kizutsukanai

The girls in both animes are not human, but are crazy in love with a normal Human boy. The girls would do any kind of crazy act to get their attention, but are often a bit unsuccessful. Boys are a bit tsundere towards the girls, eventually showing their affection. While Haiyore Nyarko san is a bit more comical, Machine Doll has a more serious tone mixed with very funny misunderstandings.
