Lala

Lala from Monster Museum/Daily Life With A Monster Girl She is stoic, gloomy, and very cold and blunt. However she apparently suffers from Chuunibyou where Lala often claims to be an agent of Death, referring to herself as both "Death Incarnate" and "The Huntress of Death". Her relationship with Kimihito is more complicated than the other girls but when she sees you as Kimihito's Siblings she starts to have feelings and a crush on you but she tries to hides it.
